Large Scale Lake Planning
Pine Lake, Shawano County, is the lower, largest, and shallowest lake of a three lake "chain" known as the Cloverleaf Lakes. Groundwater is a primary source of inflow to the chain. This, combined with a primarily wooded watershed, results in a relatively low potential for sediment and nutrient input. Water quality was fair to good for all parameters measured; transparency, nutrients and chlorophyll ~ indicated a mesotrophic status. Pine Lake stratified during summer and exhibited high nutrient levels and near-anoxic conditions near bottom in deeper portions of the basin. Macrophyte growth in Pine Lake, in general contrast to the upper lakes in the chain, occurred across a rather extensive littoral zone. Bushy pondweed (Najas sp.), a plant known to reach nuisance levels, and water celery (Vallisneria americana), a relatively desirable plant from the viewpoint of habitat provision, were most common. Water milfoil, which may include Eurasian Milfoil, an exotic species was also relatively common. Macrophyte compositional differences from that observed in adjacent Grass Lake may be related to substrate differences, e.g., generally harder substrate in Pine Lake. Overall management objectives for Pine Lake should emphasize protection and improvement/enhancement of this already high quality resource. - Regular water quality monitoring should be continued track water quality trends. Event monitoring should sources of overland drainage (parking areas, roads). Self-Help Secchi monitoring should be continued. - Riparian land owner education and diligence with respect to runoff control, yard waste and fertilizer management should be encouraged to minimize sediment and nutrient input to the lake. Runoff or erosion prone areas should be identified and protective measures implemented where possible. - Macrophyte management in near shore areas should be limited to manual harvest (if necessary or desired) to improve aesthetics and minimize build-up of organic sediments. Water milfoil species should be determined; Eurasian Milfoil, if present, should be selectively removed. - Macrophyte management should be limited to localized nuisance species control and should emphasize creation of edge and protection of desirable species assemblages.
1) Review existing lake data to define data gathering needs; 2) Initiate public involvement/information program which may include workshops, public meetings, newsletters, fact sheet, local media.3) Conduct water quality monitoring at one site as specified in the application. 4) Collect and analyze a winter sample as specified in the application. 5) Conduct a macrophyte survey as described in the application.6) Conduct a literature search on methods to control swimmers itch. 7) Prepare base maps of the lake and watershed including land use information.7) Prepare a final lake management plan that includes summary of data gathered, public involvement activities, aquatic plant survey, base and land use maps, and management recommendations.
