<br />Subwatershed 7: White Bear Lake <br /> <br />Policies: <br /> <br />A.3, B.l, B.2, B.3, B.4, B.5, C.l, Co2, C.3, C.4, C.5, E.!, E.2, E.3, EA, E.5, <br />andF <br /> <br />This subwatershed is landlocked and drains approximately 18.04 sq mi. White Bear Lake <br />dominates the hydrology of the area by providing massive storage volume for the entire <br />subwatershed. White Bear Lake was the subject of a diagnostidfeasibility study cofunded <br />between the Clean Water Partnership Program and the Clean Lakes Program. The water <br />quality of White Bear Lake is very good and a protection plan is being devised with little <br />construction work proposed other than retrofitting of existing systems. <br /> <br />White Bear Lake has a small tributary drainage area relative to its surface area which tends <br />to keep the lake clean but subjects it to large variations in water levels during times of <br />drought. The DNR is undertaking a study to define groundwater interactions and a water <br />budget for the basin. <br /> <br />Because there are relatively large amounts of storage in this subwatershed, there is little <br /> <br /> <br />need for controlling runoff rate associated with development in this subwatershed. The <br /> <br /> <br />District will concentrate on intercity drainage matters only and continue water quality <br /> <br /> <br />ponding requirements. <br /> <br />Subwatershed 8: Bald Eagle Lake <br /> <br />Policies: <br /> <br />~~~~~~~~~~~~~~~~ <br />E.5, and F <br /> <br />This subwatershed drains approximately 13.35 sq mi. Bald Eagle Lake has a high capacity <br />outlet structure which drains into Clearwater Creek. During high water conditions, Bald <br />Eagle and Otter Lakes function as a single reservoir which helps moderate flows from this <br />area. Bald Eagle Lake had a diagnostidfeasibility study performed concurrently with White <br />Bear Lake through the Clean Water Partnership and Clean Lakes Programs. Several <br />wetland restoration projects and public information programs were contemplated for <br />improving the quality of Bald Eagle Lake. From the studies, it appears the directly tributary <br />watershed of Bald Eagle is a significant source of phosphorus loading. <br /> <br />4-18 <br /> <br />10/97 <br /> <br />I <br />J <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />. <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br /> <br />I <br />
