March 2013 summary of assessment and comparisons with August 2012: The habitat assessments of two streams (SC8 and SC 10) in the vicinity of Belews Creek Steam Station (BCSS) were completed on March 20, 2013. These assessments were compared to those conducted at the same locations on August 21, 2012. The overall assessment score at SC8 in March 2013 was 54 as compared to 61 during the assessment of August 21, 2012. Dissolved oxygen (DO) was higher in March 2013 than in August 2012; while temperature, specific conductance, and pH were lower. Temperature and DO in March reflected normal seasonal differences. Forestation was much less (15 %) in March 2013 than in August 2012 (55 %), while coal ash landfill was 85% in March 2013 as compared to 45% in the summer of 2012. Depth of the stream was considerably higher in March 2013 (0.12m) than in August of 2012 (0 05m). A total of ten taxa were identified from SC8 in March of 2013. Oligocheates were most the abundant forms; while only one each of Bittacomorpha claviceps, Dystiscidae, and Hydrophiladae were counted. In August 2012, seven taxa were observed with Physa and Calopterygidae being most abundant; while Dytisciadae and Planaria were comparatively rare. Overall, both assessments listed the stream as having poor potential for wetlands development. Most other scores listed for SC8 in March 2013 were similar to those of August 2012. Monitoring personnel noted a natural berm of silt /sediment that appeared to impede stream flow. This obstruction has been removed. The overall assessment score at SC 10 in March 2013 was 28 as compared to 72 during the assessment of August 21, 2012. DO and conductivity were higher in March 2013 than in August 2012; while the March 2013 temperature was much lower due to seasonal differences. The pH values were similar. Only 15% of land use was in forestation in March 2013, as compared to 100% in August 2012; while 85% of use in March 2013 was as ash basin landfill. The survey of March 2013 showed the stream to be nearly nonexistent (width = 0.16m, depth = 0.Olin) as compared to August 2012, when the stream width was 1.52m and depth was 0.05m. A total of eleven taxa were identified from SC10 in March of 2013. Chironomids were most the abundant forms; while only one each of Ephemeridae, Perlodidae, and Hydrophilidae were observed. In August 2012, seven taxa were observed with none listed as abundant, while six were listed as rare. Limnophilidae were listed as common in 2012. Overall, both assessments listed the stream as having poor potential for wetlands development. Most other scores listed for SC10 in March 2013 were lower than those of August 2012.

The segment which is assessed should represent average stream conditions. To perform a proper habitat evaluation the observer needs to get into the stream To complete the form, select the description which best fits the observed habitats and then circle the score. If the observed habitat falls in between two descriptions, select an intermediate score A final habitat score is determined by adding the results from the different metrics.

March 2014 summary of assessment and comparisons with August 2013: The habitat assessments of two streams (SC8 and SC 10) in the vicinity of Belews Creek Steam Station (BCSS) were completed on March 19, 2014. These assessments were compared to those conducted at the same locations on August 14, 2013. The overall assessment score at SC8 in March 2014 was 52, the same as in August 2013. Dissolved oxygen (DO), temperature, and pH were lower in March 2014 than in August 2013, while specific conductance was higher. Temperature in March reflected normal seasonal variation. Forestation (10 %) was the same during both March 2014 and August 2013 assessments and coal ash landfill (90 %) was also the same. The average depth of the stream bed was 0.07 m during both assessments with maxima of 0.43 m and 0.30 m in March 2014 and August 2013, respectively. A total of nine taxa were identified from SC8 in March of 2014 with Bittacomorpha being the most abundant form, while Chironomidae, Oligocheata and Dytiscidae were rated as common. Rare forms included fish, salamanders, Physidae, Ceratopogonidae, and Tipulidae. In August 2013, twelve taxa were observed with Chironomidae being the most abundant; while Dytisciadae, Oligochaeta, and Ptychopteridae were comparatively common. Tipulidae, Tanypodinae, Tabanidae, and Corydalidae were rated as rare insect larvae. One each of crayfish, salamander, frog, and fish were observed. Overall, both assessments listed the stream as having poor potential for wetlands development. The overall assessment score at SC10 in March 2014 (28) was the same as in August 2013. The DO was higher in March 2014 than in August 2013; while the temperature, conductivity, and pH values were lower in March 2014 than in August 2013. Temperature was much lower due to seasonal differences. Only 10% of land use was in forestation during both assessments, while 90% of land use was as coal ash land fill. The survey during both assessments showed the stream to be nearly nonexistent (width = 0.16m, depth = 0.01m). A total of six taxa were identified from SC 10 in March of 2014. Oligochaeta were rated as common, while only one each of Simulidae, Tipulidae, salamander, Gammeridae, and Physidae were observed. Six taxa were also recorded in August 2013 with Physidae listed as abundant and Sphaeriidae rated as common. Rare taxa were Tipulidae, Chironomidae, Planaridae, and salamanders. Overall, both assessments listed the stream as having poor potential for wetlands development. Most other scores listed for SC 10 in March 2014 were the same as in August 2013.

Pool Variety Pools are areas of deeper than average maximum depths with little or no surface turbulence. Water velocities associated with pools are always slow. Pools may take the form of "pocket water ", small pools behind boulders or obstructions, in large high gradient streams, or side eddies. A.

Light Penetration Canopy is defined as tree or vegetative cover directly above the stream's surface. Canopy would block out sunlight when the sun is directly overhead. Note shading from mountains, but not use to score this metric. A. Stream with good canopy with some breaks for light penetration B. Stream with full canopy - breaks for light penetration absent C. Stream with partial canopy - sunlight and shading are essentially equal D. Stream with minimal canopy - full sun in all but a few areas E. No canopy and no shading Remarks Score 10 8 0 Subtotal 2 VIII. Riparian Vegetative Zone Width Definition: Riparian zone for this form is area of natural vegetation adjacent to stream (can go beyond floodplain). Definition: A break in the riparian zone is any place on the stream banks which allows sediment or pollutants to directly enter the stream, such as paths down to stream, storm drains, uprooted trees, otter slides, etc. FACE UPSTREAM Lft.
