Lake Wabasso <br />Lake Wabasso is an important recreational resource for the area. The lake is used for fishing, boating, <br />and swimming and has parkland and a public access. Based on 1997 water quality data, this lake's <br />existing classification would be Category I. Each of the water quality parameters measured fell within <br />the range expected for category I lakes. This classification indicates that by Lake Wabasso supports <br />direct contact recreational activities. Summer average water quality parameters (May-Sept., 1997) were <br />as follows: Secchi disk depth = 3.8 meters; total phosphorus = 25.9 ug/L; chlorophyll = 5.0 ug/L; and <br />TSI= 45.5. These values are consistent with a mesotrophic (moderate nutrient level) system during <br />1997. <br />Snail Lake <br />Snail Lake is a recreational resource that is used for fishing, boating, and swimming. There is a public <br />access to the lake as well as a county park. Based on 1997 water quality data, Snail Lake's existing <br />classification would be Category I. Each of the water quality parameters measured fell within the range <br />expected for a category I lake. This classification indicates that Snail Lake supports direct contact <br />recreational activities. Summer average water quality parameters (May-Sept., 1997) were as follows: <br />Secchi disk depth = 3.9 meters; total phosphorus = 23.3 ug/L; chlorophyll = 3.6 ug/L; TSI= 44.3. These <br />values are consistent with a mesotrophic (moderate nutrient level) system during 1997. <br />Bennett Lake <br />Bennett Lake is used for fishing and is associated with a city park. Based on 1997 water quality data, <br />Bennett Lake's existing classification would be Category II. This classification indicates that Bennett <br />Lake supports indirect contact recreational activities such as fishing. Secchi disk depth (1.8 meters) <br />falls within the range of category I water bodies. Total phosphorus (86.4 ug/L) during 1997 is <br />consistent with a category III classification. Chlorophyll a concentrations during 1997 (6.48 ug/L) were <br />within the range of category I water bodies. Mean trophic state index (56) is consistent with a category <br />II water body. Therefore, overall classification is category II. Water quality in Bennett Lake is <br />consistent with a eutrophic (high nutrient) system. <br />Lake Emily <br />Lake Emily has no current water quality data other than Secchi disk depth for 1.998. The Secchi disk <br />summer average depth of 1.6 meters indicates a eutrophic system. Previous classification of Lake Emily <br />Grass_lake_class_system Page 7 10/22/99 <br />
