Jeff,
Per our discussion, please find attached comments and questions provided by Jason Green of Division of Water
Resources Water Science Section. Please take these into consideration when finalizing our study plan.

NC Division of Water Resources Comments on "Broomfield Swamp Creek Reconnaissance"
Memorandum provided by CZR Incorporated.

• What rationale were used to identify Broomfield Swamp Creek as the monitoring drainage area
rather than Cypress Run? Please provide documentation of this decision -making process.
• If the entire range of physical water quality conditions are to be monitored and evaluated during
this effort, the individual parameters should be provided lie. water temp, pH, conductivity etc.).
This is not fully identified in the reconnaissance proposal. Please indicate this by site and
frequency along with all other measured parameters in a proposed study design.
• Gathering all physical water quality information will allow more accurate determination of flux
that might be observed in biological components of the monitoring plan such as fish community.
• At least one site should be considered on South Creek. The proposed study area is subject to
bidirectional flow. Water quality conditions that are geographically downstream may become
upstream as flow from South Creek enters the project area.
• To identify bidirectional flow conditions, their frequency and impact to the study area, flow
measurements need to be collected at one location within the study area. This information will
help identify changes to water level and salinity as it fluctuates due to wind driven tides present
in the Pamlico River estuary.
• Meteorological data should be collected, or determined to be available to provide watershed
specific rainfall and wind conditions. Please provide source of data if collected from existing
weather stations.
• Site locations described in the reconnaissance proposal appear to be located in an appropriate
manner along the length of the waterbody described (Broomfield Swamp Creek) and should
provide information to identify salinity gradient and water level as required.
