Water Quality Definition: Water quality issues primarily foru: o:+ the eutrophication process in the lake. Thus, the use of fertilizers in the basin and drain- age to the lake are major concerns, Background All key informants felt that water quality has imr •ved substantially in recent years. Most of the improvement is attributed to ':ersion of sewage treatment plant effluent out of the lake's drainage basin. Moweve-, several key infor- mants identified continued threats to the lake. Of the two threats most commonly mentioned, the use of fertilizers on lawns is perceived by a am It group as being the most severe. The second area most com- monly mentioned was inadequate standards imposed by regulatory agencies in con- trolling runoff "rom parking areas and construction site@ to the lake. Issues Identified 1. The Watershed District is too lax in issuing dredging permits. No construction dredging should be allowed. 3. The three major threats to water quality in the lake are: 1) fertil- izers on lawns, 2) hard surface runoff directly to the lake, and 3) shoreline erosion. 4. All new commercial and recreational developments need to provide for some form of treatment of runoff water from the site before it reach- es the lake. S. A long term monitoring program is needed, conducted in conjunction with the Freshwater Institute, the Watershed District and other in- volved agencies. Wot. '.ements for the Plan The contractor will: 1. Develop a plan along with Watershed District and the Fresh Water Institute to set regular monitoring water quality in the lake. 2. Rernmmend mechanisms • assuring th. .ater quality of the lake, par- ticularly if the monitoring program indicates a problem developing. 3. Review p{n•+s of Watershed District to determine if they are adequate to protect the quality of the Lake. 4. Evaluate t+•e stiff allocation necessary, if any, by the LMCO to as- sure the monit-+rin r•igram is implemented as designed. 5. nete.rmine the en" :mentn' social and economic consequences of the recommendations.
