Large Scale Lake Planning
Round Lake, Shawano County, is the upper, smallest and deepest (on average) 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 for the chain, results in a relatively low potential for sediment and nutrient input. Because of its small size, somewhat restricted access, and "no wake" speed limit, this lake receives comparatively lower use than the other lakes (Grass and Pine) in the chain. Water quality was fair to good for all parameters measured; transparency, nutrients and chlorophyll ~~ indicated a mesotrophic status. The lake stratified during summer and exhibited high nutrient levels and near-anoxic conditions below the thermocline. Event samples collected on the north shore of the lake showed significantly higher (than in-lake) nutrient (and probably sediment) input to Round Lake. Macrophyte growth is restricted to a narrow littoral zone which makes up only 10% of the lake area and appears to benefit the fishery resource through forage production. A predominantly softer (muck) substrate may cause compositional differences from those macrophyte assemblages observed in Grass and Pine Lakes. Overall management objectives for Round Lake should emphasize protection and improvement/enhancement of existing good water and high aesthetic quality.
1) Review existing data on lake and watershed to define data gaps and assess data gathering needs. 2) Initiate public involvement/information by workshops, public meetings, newsletters, fact sheet, and local media.3) Conduct water quality monitoring at one site as described in the application. 4) Collect and analyze one winter sample for phophorus, total Kjeldahl nitrogen, NO3-NO2, and ammonia nitrogen.5) Conduct a macrophyte survey as described in application. 6) Prepare base map of lake and watershed containing land use information including soil disturbing land uses, nonpoint pollution problems, and environmentally sensitive areas.7) Include in final lake management plan summary of data gathered, public involvement activities, aquatic plant survey, base and land use maps, and management recommendations.
