Water Bodies have poorer water quality than Category I water bodies but are still popular with the public. Category II water bodies are discussed individually in the following pages and include: • Lake Emily • Shoreview Lake • Island Lake 1. Lake Emily (DNR ID No. 62-80W) Lake Emily is located in south central Shoreview. Lake Emily has a surface area of approximately 13 acres, a maximum depth of about 15 feet, and. an average depth of 7 feet. All of the land surrounding Lake Emily is privately owned and therefore there is not a public access. Residents who live on the lake use it primarily for boating and fishing. Surface water from Lake Emily flows through a wetland, then into Charlie Pond in Roseville, and finally into Lake Owasso as illustrated in Figure 12. Only one water level has been recorded by the Minnesota DNR in 1979 on Lake Emily. The MPCA along with their Citizen Monitoring Program have collected water quality data since 1980. The trend analysis completed as part of the GLWMO Watershed Management Plan (September 2001), shows that there are significant tends in Secchi disc readings. These data indicate that there has been negative trend in Secchi disc readings since 1990. In general the Secchi disc depths indicate that Lake Emily is a eutrophic lake. Sufficient data is not available on total phosphorus and chlorophyll a to conduct a trend analysis. Within the Lake Emily subwatershed, there are two drainage areas (LE-1 and LE-3) which do not meet the water quality treatment criteria as shown in the water quality assessment data in Appendix E. However, drainage area LE-1 drains to LE-2 which provides enough water quality treatment for both drainage areas. Similarly, LE-3 drains to LE-4, which also provides enough water quality treatment for both drainage areas (see Figure 12). Because Lake Emily is a Category II water body and the water clarity trend is current downward, the City intends to encourage development and redevelopment projects in LE-5 to evaluate the benefits of additional water quality treatment BMPs beyond the basis City requirements. The City will also look for opportunities to incorporate BMPs into municipal projects in drainage area LE-5. 2. Shoreview Lake (DNR (D No. 62-79W) Shoreview Lake is located in the south central portion of the City in the upper reaches of the Lake Wabasso watershed. There is limited information available on Shoreview Lake, from the City, WMO and regulatory agencies. Shoreview Lake is generally not used for recreational activities. Shoreview Lake is within a relatively small self-contained drainage area with only the immediate drainage area draining into the lake. The drainage area has sufficient water quality treatment based on the water quality assessment summarized in Appendix E. Shoreview, MN Page 51 2"d Generation: Surface Water Management Plan March 2005
