These alternatives <br />ranged from administrative alternatives such as fertilizer management education programs, to <br />structural alternatives such as the construction of nutrient reducing detention basins. Each of <br />the options was evaluated for its benefit in improving water quality, estimated initial and long ­ <br />term (operation and maintenance) costs, and technical teasibility. <br />The most technically sound and cost-effective options were incorporated into the implementation <br />plan for improving Long Lake. The final plan elements include the foUowing: <br />A local public information/education committee which will focus on <br />informing, enlisting cooperation, and improving fertilization practices <br />of local landowners. <br />Street cleaning to capture potential pollutants before they are mixed <br />with stormwater runoff and transported to the lake. <br />Construction of deie.ntion basins to reduce the load of pollutants <br />delivered to the lake via runoff from northern subwatersheds. <br />Aeration systems to maintain areas of well oxygenated water in the <br />hypoliminion, reduce mtemal phosphorus loading, and improve the <br />sport fishery. <br />Development of a fisheries management plan to improve the <br />recreational fishery in the lake.
