on the upper southwest shore and more formally referred to as Lake Almanor West, itself an un-gated country-club The generally nameless western shoreline from Lake Almanor West to the town of Chester, starting at Goose Bay and ending at the termination of the large diversion channel that mitigates high-waters in the Feather River above Chester The northern shoreline from Chester, running northeast then southwest, and back to Hwy 36; includes the mouth of Benner and Last Chance creeks and seasonal springs Much of the southern shore of the lake is in the Lassen National Forest, so recreation management is shared by PG&E and the United States Forest Service. Large areas along the northern shore of the lake are seasonal pastures used for summer and fall cattle grazing; some areas of these grazing grounds are underwater in wetter years. The wetlands at the north end also serve as breeding grounds for a variety of migratory waterfowl, most prominently Canada geese and various species of ducks including mallard, teal, and wigeon. Other large birds to be viewed around the lake are heron, osprey, and occasionally bald eagles, which nest on the Peninsula and West Shore. Each year in late June and early July, large insect hatches occur on the lake during dusk. The insects on which the fish feed attract local fly fishermen who use imitation flies to catch the feeding fish. The Almanor Basin Watershed Advisory Committee Group (ABWAC) received funding for a Watershed Assessment Project under California Prop 12, and one deliverable from this project was in an online map-based database of watershed information that runs on Google Earth.

Thermal curtain PG&E's 50-year license to use the waters of Lake Almanor was set to expire in 2004 when the state water board explored requests to install a thermal curtain at the bottom of Lake Almanor to control the temperature of the rivers downstream. This was ostensible to create better habitat for trout habitat up to 40 miles downstream. However, residents near Lake Almanor became concerned that the curtain would help the trout downstream at the cost of raising the water temperatures of shallow Lake Almanor and harming its fish population. By doing so, the residents would not have easy access to the lake's fish. Power production There is no powerhouse at the dam. A tunnel (and finally a penstock) from the powerhouse outlet tower, in
