WAPOGASSET/BEAR TRAP LAKE IMPROVEMENT DIST: Wapogasset/Bear Trap Lakes Water Qual Monitoring & Assessmt

Estimate internal load components of the lakes' annual phosphorous budgets from field data on temporal changes in lake phosphorus concentrations. Construct time-depth isopleth diagrams of water temperature, and dissolved oxygen and total dissolved phosphorus concentrations. Determine the likely scope and cost of an alum treatment project designed to mitigate recycle of phosphorus from anoxic sediments into the overlying lake waters. Estimate the effectiveness and longevity of a lake alum treatment from a literature search. Disseminate information to the public by newsletter, report mailings, public meeting, and local newspaper articles.
