F <br />As in County Road 6 basin, the ana surrounding the sedimenation basin will be <br />sodded to improve sabflity and aesthetics. Indigenous wetland trees and shrubs will <br />also be planted along the basin’s perimeter. <br />4. Aeration System <br />Two in-Iake hypolimnetic aeration units will be crated for Long Lake a: the locations <br />indicated in Figure 6. An in-Iake aeration unit is shown conceptually in Figure 8. The <br />system will incorporate a land-based air compressor which will supply air to the two in-lake <br />units. <br />Because Long Lake comprises two basins, while a primary goal is to reduce phosphorus <br />release from anoxic sediments in both, the use of two aeration units was selected. This will <br />increase the areal coverage of the system significantly and will ensure the aeration of the <br />whole lake hypolimnion. addition, ferric chloride, as an iron source, will be supplied into <br />the lake hypolimnion. ' his will further reduce the phosphorus concentraion and ensure high <br />phosphorus retention efficiency. <br />The aeration system will be operated yor-round to prevent anaerobic conditions in the lake <br />during the summer and winter months, and thereby reduce the high sediment phosphorus <br />loading. The ferric chloride, on the other hand, will be supplied into the over the <br />seven- to eight-month open water season only. <br />5. Fishery Management <br />One of the goals of the Long Lake project is to improve recrational fishery in the lake. The <br />development of a fishery management plan which may include stocking of selected fish <br />species is part of this project element.
