Lower Red Lake, Shawano County, Wisconsin, is an impoundment of the Red River created by construction of a dam in 1965. Its location, immediately downstream from Upper Red Lake (impoundment created in 1880), makes Lower Red Lake a rather unique impoundment in that parent river inflow is "sediment poor". A primarily forested watershed also contributes to relatively low sediment and nutrient input to the system as a whole. Lower Red Lake water quality is presently good with respect to all parameters measured but appears to be affected by periodic nutrient "pulses". Upper and Lower Red Lakes, despite similar watersheds, chemical water quality and basin morphometry, support dense but taxonomically different macrophyte populations. Differences are probably related to impoundment age (successional implications) or location (associated substrate or physical water quality differences) and should be investigated further before intensive macrophyte management or habitat manipulation is initiated. Long term management should emphasize water quality maintenance/enhancement and macrophyte management to improve accessibility and fishery potential. Specific near-term recommendations include: -Identification of non-point sources and implementation of preventative riparian land use practices to retard localized sediment or nutrient inflows - Continued study of macrophytes with emphasis on substrate and habitat relations in areas of highest concern - Localized application of macrophyte harvest alternatives to create access lanes and "edge" effect - Follow-up evaluation of macrophyte control techniques to determine the most cost effective and temporally efficient methods available for long-term application

Assemble and review existing data on the lake and watershed. Define data gaps from above and gather additional infromation to include: a) water quality sampling at 3 sites to include all or some of the parameters in table 1 of the application,b) sediment sample to be analyzed for % organics, total solids, total-P, ammonia N, Kjeldahl N. Develop and implement a public involvement program. Prepare land use map for lake and watershed. Identify and evaluate existing ordinances related tonon-point pollution control. Develop draft report for public review and comment. Prepare and distribute lake management plan. Information will be disseminated through newsletter mailings, fact sheet distributions, public meetings, local newspaperarticles, and TV/radio spots (if possible). Project results will be reposited at Town Halls (Herman and Red Springs), Village Hall (Gresham), and County Courthouse (Shawano).
