1.0 EXECUTIVE SUMMARY
This Annual Monitoring Report details the monitoring activities during the 2012 growing season
(Monitoring Year 1) for the Candiff Creek Restoration Project ( "Site ") As per the approved
Mitigation Plan for the Site, this Annual Monitoring Report presents stream geometry data, stem
count data from vegetation monitoring stations, and discusses any observed tendencies relating
to stream stability and vegetation survival success
Prior land use on the Site consisted primarily of pasture and forest Candiff Creek had been
channelized and riparian vegetation had been cleared in the lower half of the site The upstream
reaches of the project had a narrow, early successional buffer that included several exotic
vegetation species Prior to restoration, Candiff Creek was incised and lacked bedform diversity
As a result, channel degradation was widespread throughout the Site
A total of 13 monitoring plots, 100 square meters (m2) (IOM x 10m) in size, were used to predict
survivability of the woody vegetation planted on the Site Data from Year 1 monitoring for the
13 vegetation plots exhibited a survivability range of 728 to 1,052 stems per acre The data
showed that the Site had an average survivability of 878 stems per acre following Year 1
monitoring
According to the Year 1 vegetative monitoring data, the Site is on track to meet the interim
success criteria of a minimum of 320 stems per acre by the end of Monitoring Year 3
Cross - sectional monitoring data for stream stability were collected during Year 1 monitoring A
longitudinal profile survey was completed during Year 1 monitoring for approximately 3,674
linear feet (LF) of stream on the Site The longitudinal profile was completed for Reach M3
only
The cross - sectional data and the longitudinal profile indicate that Reach M3 is stable and
functioning as designed
According to the on -site crest gauge, the Site experienced at least one bankfull flow event during
the Year 1 monitoring period The largest on -site bankfull flow event documented by the M3
crest gauge during Year I monitoring, occurred sometime in April -May 2012 It was estimated
that flows at the M3 crest gauge during this time period were approximately 160 feet above
bankfull stage Inspection of conditions during a spring site visit revealed visual evidence of out -
of -bank flows ,
In summary, the Site is on track to meet the hydrologic, vegetative, and stream success criteria as
specified in the Site Restoration Plan
Candiff Creek Restoration Project, EEP Project No 92767
January 2013, Monitoring Year 1 FINAL
2.0 PROJECT BACKGROUND
The project involved the proposed restoration of 4,109 linear feet (LF) of stream, 1,757 of stream
Enhancement (265 LF of Enhancement I and 1,492 LF of Enhancement II) and 1,200 LF of stream
preservation The final stream lengths for all reaches are shown in Table 1 and Figure 2 summarize
the restoration zones on the Site A total of 27 54 acres of stream and riparian buffer are protected
through a permanent conservation easement
2.1 Project Objectives
The specific goals for the Candiff Creek Restoration Project were as follows
• Create geomorphically stable conditions along Candiff Creek through the project area
• Prevent cattle from accessing the project reaches, reducing excessive bank erosion,
• Improve habitat quality in a riffle dominated stream by adding pool /riffle sequences and
expanding the floodplam, while improving overall ecosystem functionality
• Improve water quality within the Candiff Creek Restoration Project area through reduction of
bank erosion and reductions in nutrient and sediment loads
• Stabilize streambanks through installation of in- stream structures and establishing a riparian
buffer consisting of native plant species
• Improve aquatic and terrestrial habitat through increased substrate and >n- stream cover,
additional woody debris, and reduced water temperature by increasing stream shading, and
restored terrestrial habitat
2.2 Project Structure, Restoration Type and Approach
For analysis and design purposes, Michael Baker Engineering, Inc (Baker) divided on -site streams
into reaches The reaches were numbered sequentially from upstream to downstream, with a "M"
designation for the "mamstem" and a "UT" designation for unnamed tributaries Two UTs are
located on the Site (labeled UTI and UT2) The on -site streams are described as follows M1 begins
on the upstream section of the Site at the River - Siloam Road culvert, and then flows southward to
the confluence with UT2 M2 begins at the Ml/UT2 confluence and flows south 265 feet to the
beginning of the restored portion of the mainstem M3 begins at the restored channel and then flows
southeastward for 4,123 feet and terminates at the property line adjacent to the Yakin Valley
Railroad right -of -way located at the downstream end of the Site UTI flows onto the Site from the
southern Wall property line and flows southward for 885 feet to the confluence with M1 UT2 flows
onto the Site from the eastern Aztar Group, LLC property line and flows eastward for 1,162 feet and
terminates at the Ml/M2 transition The reaches described above are presented in the plan sheets
located in Figures 3A through Figure 3J
The restoration design allows stream flows greater than the designed bankfull elevation, to spread
onto the floodplam, dissipating flow energies and reducing stress on streambanks In- stream
structures were used to control streambed grade, reduce streambank stress, and promote bedform
sequences and habitat diversity The in- stream structures installed consist of constructed riffles,
cover logs, log /rock vanes, log /rocky -hook vanes, rock cross vanes, vegetated geolifts, vegetated
brush mattresses and root wads These structures promote a diversity of habitat features in the
restored channel Where grade control was a consideration, constructed riffles, grade control rock j-
hook vanes, and rock cross vanes were installed to provide long -term stability Streambanks were

stabilized using a combination of erosion control matting, temporary and permanent seeding, bare -
root planting, transplants, brush mattresses and geolifts Transplants provide areas for living root
mass to increase streambank stability and also to create holding areas for fish and aquatic biota
The purpose of the project is to restore stream functions to the impaired reaches the Site Native
species vegetation was planted across the Site and the entire project area is protected through a
permanent conservation easement

3.0 PROJECT CONDITION AND MONITORING RESULTS
3.1 Vegetation Assessment
3.1.1 Description of Vegetative Monitoring
As a final stage of construction, the stream margins and riparian areas of the Site were
planted with bare root trees, live stakes, and a seed mixture of temporary and permanent
herbaceous vegetation to establish ground cover The woody vegetation was planted
_ randomly from the top of the stream banks to the outer edge of the project's re- vegetation
limits In general, bare -root vegetation was planted at a target density of 680 stems per acre,
in an 8 -foot by 8 -foot grid pattern Live stakes were installed two to three feet apart in
meander bends and six to eight feet apart in the riffle cross - sections The live stakes were set
up using triangular spacing along the stream banks between the toe of the stream bank and
bankfull elevation The tree species planted at the Site are shown in Table 5 The temporary
seed planted following construction was rye grain The permanent seed mix of herbaceous
species planted in the project's riparian area included redtop (Agrostis alba), big bluestem
(Andropogon gerardn), beggartick (Bidens frondosa), lanceleaf tickseed (Coreopsis
lanceolata), deertongue (Pancium clandestinum), Virginia wildrye (Elymus virginicus), soft
rush (Juncus effusus), switchgrass (Panicum virgatum), smartweed (Polygonum
pensylvanicum), little bluestem (Schizachyrium scoparium), Indian grass (Sorghastrum
nutan), and eastern gamma grass (Tripsacum dactyloides) This seed mixture was broadcast
on the Site at a rate of 15 pounds per acre All planting was completed in April 2012
At the time of planting, 13 vegetation plots — labeled 1 through 13 - were established on -site
to monitor survival of the planted woody vegetation Each vegetation plot is 0 025 acre in
size, or 10 meters x 10 meters All of the planted stems inside the plots were flagged to
distinguish them from any colonizing individuals and to facilitate locating them in the future
The trees also were marked and labeled with aluminum metal tags to ensure that the correct
identification is made during future monitoring of the vegetation plots In addition to
flagging and tags, the locations of planted stems and vegetation plot corners were recorded
by use of survey equipment
3.1.2 Vegetative Success Criteria
To characterize vegetation success criteria objectively, specific goals for woody vegetation
density have been defined Data from vegetation monitoring plots should display a surviving
tree density of at least 320 trees per acre at the end of the third year of monitoring, and a
surviving tree density of at least 260 five- year -old trees per acre at the end of the five -year
monitoring period

3.1.3 Vegetative Observations and Results
Permanent ground cover has been successfully established at the Site through the planting of
the permanent seed mixture planted at the Site, as observed during Year 1 monitoring of the
Site
Tables A 1 through A 6 in Appendix A present vegetation metadata, vegetation vigor,
vegetation damage and stem count data for the monitoring stations at the end of Year 4
monitoring Data from Year 1 monitoring for the 13 vegetation plots exhibited a range of
728 to 1,052 stems per acre The data show that the Site had an average survivability of 878
stems per acre following Year 1 monitoring In comparison, following as -built conditions,
the Site demonstrated an average survivability of 915 stems per acre
Trees within each monitoring plot are re- flagged regularly to prevent planted trees from
losing their identifying marks due to flag degradation It is important for trees within the
monitoring plots to remain marked to ensure they are all accounted for during the annual
stem counts and calculation of tree survivability Labeled aluminum tags with wire hangers
are used on surviving stems to aid in relocation during future counts The aluminum tags are
removed from each stem once the tree becomes established and is recognizable by species
during plot monitoring Flags are also used to mark trees because they do not interfere with
the growth of the tree
All plots will continue to be assessed during Year 2 monitoring for occurrence of volunteer
species -
3.1.4 Vegetative Problem Areas
During Year 1 monitoring, kudzu (Pueraria montana) was observed on the Site in the
vicinity of vegetation Plot 13 This concentration of kudzu is located on the upstream portion
of Reach M1, downstream of River - Siloam road This area of kudzu was previously treated
during construction This area of kudzu is scheduled to be treated again during the
appropriate time(s) in 2013
There are relatively few weedy species occurring on the Site, and none of the on -site species
seem to be posing any issues for the planted woody or herbaceous hydrophytic vegetation at
this time
3.1.5 Vegetation Photographs
Photographs are used to visually document vegetation plot success A total of 13 reference
stations were established to document tree conditions at each vegetation plot across the Site
Reference photos of tree plots are taken at least once per year Photos of the tree plots for
Year 1 monitoring that show the on -site planted stems are included in Appendix A of this
report
3.2 Stream Assessment
3.2.1 Morphometric Success Criteria
To document the stated success criteria, the following monitoring program was instituted
following construction completion on the Site
Candiff Creek Restoration Project, EEP Project No 92767 1 1
January 2013, Monitoring Year 1 FINAL
Cross - sections Two permanent cross - sections were installed per 1,000 LF of stream
restoration'work, with one of the locations being a riffle cross - section and one location being
a pool cross - section in each series A total of 10 permanent cross - sections were established
across the Site Each cross - section was marked on both banks with permanent pins to
establish the exact transect used The permanent cross - section pins are surveyed and located
relative to a common benchmark to facilitate easy comparison of year -to -year data The
annual cross - section surveys include points measured at all breaks in slope, including top of
bank, bankfull, inner berm, edge of water, and thalweg
The approved Mitigation Plan requires the following criteria be met to achieve stream
restoration success
• There should be little change in as -built cross - sections
• If changes do take place, they will be evaluated to determine if they represent a
movement toward a more unstable condition (e g , down - cutting or erosion) or a
movement toward increased stability (e g , settling, vegetative changes, deposition
along the banks, or decrease in width/depth ratio)
• Cross - sections will be classified using the Rosgen Stream Classification System
(Rosgen, 1994), and all monitored cross - sections should fall within the quantitative
parameters defined for channels of the design stream type
Longitudinal Profiles A complete longitudinal profile was surveyed following construction
completion to record as -built conditions and to establish a baseline profile The profile was
conducted for the entire length of each restored channel for all reaches Measurements
included thalweg, water surface, inner berm, bankfull, and top of low bank Each of these
measurements was taken at the head of each feature (e g , riffle, pool, and glide) In addition,
maximum pool depth was recorded All surveys were tied to a single, permanent benchmark
The approved Mitigation Plan requires the following criteria be met to achieve stream ' -
restoration success
• A longitudinal profile will be completed annually for the five -year monitoring period
• The profile will be conducted for 3,000 LF of restored Candiff Creek channel
• The longitudinal profiles should show that the bedform features are remaining stable,
i e , they are not aggrading or degrading
• Pools should remain deep, with flat water surface slopes, and the riffles should
remain steeper and shallower than the pools
• Bedforms observed should be consistent with those observed for channels of the
designed stream type
3.2.2 Morphometric Results
Year 1 cross - section monitoring data for stream stability was completed during October
2012 The 10 permanent cross - sections along the restored channels (5 located across riffles
and 5 located across pools) were re- surveyed to document stream dimension at the end of
Monitoring Year 1 Data from each of these cross - sections are presented in Appendix B
CandlffCreek Restoration Project, EEP Project No 92767 12
January 2013, Monitoring Year 1 FINAL
Cross - sections 1, 4, 6, 8 and 10 are situated across riffles that are located between pools
Based on the survey data, Cross - sections 6, 8 and 10, located on the mid- downstream portion
of M3, showed relatively little change since as -built conditions Cross - sections 1 and 4 are
located on the upstream portion of M3 and demonstrated minor fluctuations in riffle
dimensions during the first year of monitoring Cross - sections 1 and 4 appear to have
aggraded in channel dimension slightly since as -built conditions The left bank of Cross-
section 1 also appears to have increased in elevation It is likely that the changes observed in
Cross - sections 1 and 4, both at riffles, are due to the spring rains which also marked the
highest bankfull readings for Year 1 monitoring These two cross - sections will be closely
observed during Year 2 monitoring
Cross - sections 2, 3, 5, 7 and 9 are situated across pools which are located at the apex of
meander bends Based on the survey data, Cross - sections 2, 3 and 5 have shown relatively
little change since as -built conditions However, Cross - sections 7 and 9 have demonstrated
minor fluctuations in pool dimensions since as -built conditions Cross - sections 7 and 9 are
located on the downstream portion of M3 and appear to have aggraded slightly since as -built
conditions It is likely that the morphological changes observed in Cross - sections 7 and 9,
both at pools, are also due to the spring rains Based on the Year 4 monitoring survey data,
all pool cross - sections show the slow development of point bar features on the inside banks
of the meander bends
The longitudinal profile for Year 1 monitoring was completed in October 2012 The Year 1
monitoring data were compared to the data collected during the as -built condition survey
completed in April 2012 During Year 1 monitoring, the longitudinal profile survey was only
completed for Reach M3 A total stream length of 3,674 LF was surveyed for M3 The
longitudinal profiles for these reaches are presented in Appendix B
Year 1 monitoring data for the M3 longitudinal profile indicate that the riffles in this reach
have essentially maintained the same bed elevations since as -built conditions However,
some pools in M3 have continued to increase in depth since as -built conditions It is noted
that increased pool depths were observed mostly in the middle of portion of M3 The deeper
pools in M3 are providing increased channel stability while promoting greater habitat
diversity It is likely that the morphological changes observed in Cross - sections 7 and 9,
both at pools, are again attributed to the spring rains Overall, the longitudinal profile for M3
demonstrates that the in- stream structures within the reach are stable and functioning as
designed
In- stream structures installed within the restored stream included constructed riffles, log
vanes, grade control rock and log J -hook vanes, rock cross vanes, root wads and stream
crossings Visual observations of these structures throughout Year 1 monitoring indicated
that all structures are functioning as designed and holding their post - construction grade
Structures that were installed to develop deep pools, such as cross vanes and j- hooks, are
performing their designed functions Log vanes placed in meander pool areas have provided
scour to keep pools deep and provide cover for fish J -hooks placed in lower end of the riffle
areas have maintained riffle elevations and provided downstream scour holes that provides
aquatic habitat Root wads placed on the outside of meander bends have provided bank
stability and in-stream cover for fish and other aquatic organisms

January 2013, Monitoring Year 1 FINAL
3.2.3 Hydrologic Criteria
One crest gauge was installed on the Site to document bankfull events The gauge is checked
during each site visit and records the stage of the highest out -of -bank flow between site
visits The gauge is located on the left bank on the downstream portion of M3 at station
55 +50
The approved Mitigation Plan requires the following criteria be met to achieve stream
restoration success Two bankfull flow events must be documented within the five -year
monitoring period The two bankfull events must occur in separate years, otherwise, the
stream monitoring will continue until two bankfull events have been documented in separate
years
3.2.4 Hydrologic Monitoring Results
According to the on -site crest gauge, the Site experienced at least one bankf ill flow event
during Year lmomtoring The largest on -site bankfull flow event documented at the UT1
crest gauge during Year 1 monitoring, occurred in April -May 2012 It is estimated that the
stage of the highest flow at the M3 crest gauge during April -May 2012 was approximately
160 feet above bankfull stage Following the April -May 2012 storm events, the crest gauge
on M3 did not document additional out of channel bankfull flows for the remainder of Year 1
monitoring
Crest gauge readings are presented in Table 6 and photos of the crest gauges and out -of -bank
evidence are presented in Appendix B

3.2.5 Stream Problem Areas
During Monitoring Year 1, there were no stream problem areas observed at the Site
3.2.6 Stream Photographs
Photographs are used to document restoration success visually A total of 59 reference
stations were installed and photographed after construction Photographs of these reference
stations will be collected for at least five years following construction Reference photos are —
taken at least twice per year, and are taken in enough locations to document the condition of
the restored system Permanent markers were established to ensure that the same locations
(and view directions) on the Site are documented in each monitoring period
Candiff Creek Restoration Project, EEP Project No 92767 14
January 2013, Monitoring Year 1 FINAL
The stream systems are photographed longitudinally, beginning at the downstream portion of
the restoration reaches, and moving upstream to the beginning of the reaches Photographs
are taken looking upstream at designated locations Reference photo locations are marked
and described for future reference Points are spaced sufficiently close to provide an overall
view of the reach The angle of the photograph depends on which direction provides the best
view and is noted and will be continued for future photos When modifications to photo
position and/or direction are made due to obstructions or other reasons, the modified photo
position and /or direction is noted, along with any landmarks The same position is used in
the future
Additional photographs are taken to document any observed evidence of flooding patterns
such as debris, wrack lines, water marks, channel features, etc
Also, both stream banks are photographed at all permanent cross - section photo stations For
each stream bank photo, the photo view line follows a survey tape placed across the channel,
perpendicular to flow (representing the cross - section line) The photograph is framed so that
the survey tape is centered in the photo (appears as a vertical line at the center of the
photograph), keeping the channel water surface line horizontal and near the lower edge of the
frame In each cross - section photo showing the left bank, flow is moving to right
Conversely, in each cross - section photo showing the right bank, flowing is moving to the
left
A photo log of the restored channel is presented in the attached CD of this report Photos for
each of the 10 permanent cross - sections are included in Appendix B
Photographs of the restored channel were taken in October 2012 to document the evolution
of the stream geometry Herbaceous vegetation and shrubs were dense along the banks of
M2 and M3, making the photography of some of the stream channel areas difficult
3.2.7 Stream Stability Assessment
Table B 1 provides a summary of the results obtained from the visual inspection of in- stream
structures performed during Year 1 monitoring The percentages noted are a general, overall
field evaluation of the how the features were performing at the time of the photo point
survey According to the visual stability assessment following Year 1 monitoring, and after a
visual evaluation throughout 2012, it was determined that all features at the Site are currently
performing as designed However, it is noted that the pool in Cross - section 7 has aggraded
slightly This pool will be closely observed during Year 2 monitoring and future site visits
3.2.8 Quantitative Measures Summary Tables
The quantitative pre - construction, reference reach, and design data used to determine
restoration approach, as well as the as -built baseline data used during the project's post
construction monitoring period are summarized in Appendix B
Candlff Creek Restoration Project, EEP Project No 92767 15
January 2013, Monitoring Year 1 FINAL
4.0 OVERALL CONCLUSIONS AND RECOMMENDATIONS
Stream Monitoring - The total length of stream channel restored on the Site was 4,123 LF This
entire length was inspected during Year 1 monitoring to assess stream performance Year 1
monitoring did not reveal any significant problem areas within the boundaries of the Site
Cross - section monitoring data for stream stability were collected during Year 1 monitoring A
longitudinal profile survey was also completed during Year 1 monitoring for approximately
3,674 LF of stream on the Site The longitudinal profile was completed for Reach M3 only
Year 1 monitoring data for the M3 longitudinal profile show that the riffles in this reach have
maintained relatively the same bed elevations since as -built conditions The longitudinal profile
demonstrates that the in- stream structures within M3 are stable and functioning as designed
The cross - sectional data and the longitudinal profile indicate that Reach M3 is stable and
functioning as designed
According to the on -site crest gauge, the Site experienced at least one bankfull or greater flow
event during Year 1 monitoring The largest on -site bankfull flow event documented by the M3
crest gauge during Year 1 monitoring occurred approximately in April -May 2012 It was
estimated that the stage associated with these flows at the M3 crest gauge during this period was
approximately 160 feet above banlAll stage Inspection of conditions during a spring site visit
revealed visual evidence of out -of -bank flows
Vegetation Monitoring - Data from Year 1 monitoring for the 13 vegetation plots exhibited a
range of 728 to 1,052 stems per acre The data showed that the Site had an average of
survivability of 878 stems per acre
During Year 1 vegetation monitoring, kudzu was observed on the Site in the vicinity of
vegetation Plot 13 This concentration of kudzu is located on the upstream portion of Reach Ml,
downstream of River - Siloam road This area of kudzu was previously treated during
construction This area is scheduled to be treated again in 2013 during appropriate treatment
window(s)
According to the Year 1 vegetative monitoring data, the Site is on track to meet the interim
success criteria of 320 stems per acre by the end of Year 3 monitoring
