Specifications include, but are not limited to: The scope of work for this project is to develop a Watershed-based Management Plan following the U.S. EPA Nine-Element (a-i) Framework further detailed in the Clean Water Act Section 319 Guidance for Watershed Management Plan. The overall project and scope of work represent a collaboration of entities working on various tasks and aspects of the project. The Plan development will include some or all of the following tasks: 1) Quantify the mechanisms of phosphorus loading to Silver Lake by examining tributary and internal lake sources. Identify land use sources (direct runoff, septic systems, etc.) that may be contributing to total phosphorus. 2) Identify land use strategies for mitigating loading from direct runoff to the lake. 3) Develop a report for Silver Lake that measures stream flow to calculate tributary phosphorus loading. 4) Incorporate detailed measurements of dissolved oxygen and total phosphorus in the water columns of Silver Lake into lake models for calculating phosphorus loading dynamics. 5) Measure the total phosphorus content in the lake and examine sediment storage and release of phosphorus. 6) Calculate the total phosphorus budget for each subwatershed.
