BIG CHETAC CHAIN LAKE ASSOCIATION: "Getting Rid of the Green" Project-Phase 2

Big Chetac Chain Lake Association is sponsoring a multi-phase comprehensive lake management planning project for Big Chetac Lake, Sawyer County. The project includes tributary, in-lake, and groundwater monitoring; septic survey; nutrient budget development; paleoecological core; aquatic plant survey and management plan; and community survey and education with a comprehensive lake management and implementation plan as the final deliverable.

Phase 2 includes:

1. Installation (two times) of fourteen mini-piezometers to determine direction and extent of groundwater movement. Those with positive heads will be sampled for nutrients.

2. Internal load calculations under various conditions (oxic/ambient pH, oxic/high pH, and anoxic) for cores collected at the three deep sites and one shallow site - to be completed by the Army Corps of Engineers ERDC Eau Galle Aquatic Ecology Laboratory staff.

3. GPS mapping and density estimates of curlyleaf pondweed beds for comparison to previous mapping/survey.
