Nine such dams were completed during the biennium, three were started but not completed, and one previ- ously constructed dam was raised to increase the water storage. Other Flow Maintenance Irrigation waters were channelized into Pine Creek, Lassen County, facilitating downstream migration of trout into Eagle Lake. Gravel wing dams were constructed with bulldozers on the lower Eel River, Humboldt County, to deepen the channel and minimize losses of anadromous fish attempting to enter the river. This was accomplished with Federal Aid funds. Lake Construction and Improvement Work was begun on Indian Basin Lake, Fresno County, where a trout lake of about nine acres in size will be constructed with Wildlife Conservation Board funds. This work is being done by a contract with the U. S. Forest Service. Preliminary surveys have been made at several other sites to determine feasibility of constructing other trout and warmwater lakes. At Doane Lake in San Diego County, the marginal area was deepened, an old dam removed, and vegeta- tion controlled under a Wildlife Conservation Board project. The bed of Dry Lake, San Bernardino County, was treated with bentonite to eliminate water loss through seepage. A diversion ditch was opened from Little Kern Lake Creek, Tulare County, to provide a constant flow of water into Little Kern Lake. A more permanent head- works structure is planned for the next biennium. In accordance with instructions from the Legisla- ture, the department made a survey of the snags and logs in Lake Almanor, Plumas County, to determine the feasibility of removing them. The survey indicated that their removal would cost about $1,600,000. Stream Improvement Devices Spearheaded by a Wildlife Conse
