Document Description: The project is limited to replacement of several small porous, flat, plates in test areas on the lake bottom within the lagoons in the Tahoe Keys development at South Lake Tahoe. Compressed air, from a compressor system located on the adjacent lakeshore, will be pumped through the plates creating a laminar flow situation. This is predicted to significantly decrease the level of fine, organic, particulate materials being deposited on the lake bottom, and increase levels of dissolved oxygen, which is project in turn, to decrease the ability of invasive , non-native aquatic vegetation to grow within the test areas. Divers will place the porous plates on the lakebed within the test areas. It will not be necessary to drain or alter the water level within the test area.

Exempt Status: Categorical Exemption
Type, Section or Code: C:1,4,6,33
Reasons for Exemption: S:15301, 15304, 15306, 15333 This is a very small experimental project involving the investigation into the efficacy of a new, laminar flow technology for the control and eradication of non-native, invasive aquatic vegetation within the confines of the Tahoe Keys Waterways. The results of the rest will be used, in part to determine, if this technology can be up scaled as an effective means of controlling an otherwise out of control, invasive aquatic weed problem in the Keys.
