* The Jefferson County Conservation District chose to conduct water quality sampling (not a requirement by Ecology for integrated plans) because grass carp was a possible option for control. The plant sampling was also more rigorous than required by Ecology guidelines. The requirements for obtaining a grass carp permit for public lakes include collecting lake water quality data and plant biomass data.

The Lake Leland Plan is available at the Department of Ecology Library, the State Library, and the Jefferson County Conservation District.
