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; pale ecological 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 4 includes: 1. Collection of a sediment core from Lake Chetac. 2. Reconstruction of the limnological history of Lake Chetac from information deposited in the sediments. The Phase 4 will answer the following questions: determine changes in nutrients over the last 130 years; have the frequency of algae blooms increased during the last century; have the macrophyte growth changed during the last century; and an estimate of major sources of increased nutrient input. Data, records, and reports, including GIS-based maps and digital images, must be submitted to the Department in a format specified by the regional Lake Coordinator.
