Located in Plumas National Forest, Lake Davis is the centerpiece of the Lake Davis Recreation Area, which supports boating, campground camping, cross-country skiing, fishing, hunting, mountain biking, picnicking, snowmobiling, swimming, and wildlife viewing.{{Cite web|url=http://www.fs.usda.gov/recarea/plumas/recreation/camping-cabins/recarea/?recid=11185&actid=29|accessdate=November 17, 2012|title=Grizzly Campground}}

During 1996-97 Lake Davis was in the national spotlight due to controversy over northern pike and the possibility of poisoning the lake. Following an explosion of the pike population, and the California Department of Fish and Game (DFG) decided to treat the reservoir with rotenone, a naturally occurring poison deadly to gilled creatures.{{Cite web|url=http://www.dfg.ca.gov/lakedavis/history.html|title=Lake Davis Fisheries Management|accessdate=November 17, 2012}}

After the first attempt failed to eradicate the pike and the population rebounded, the DFG again utilized rotenone in September 2007, after lowering the water level.{{Cite news |first=Tamara |last=Keith |title=California Poisons Lake, Targeting Invasive Pike |url=https://www.npr.org/templates/story/story.php?storyId=14698649&ft=1&f=1001 |work=All Things Considered |publisher=National Public Radio |date=2007-09-25 |accessdate=2007-09-25 }} DFG's justification for the action was their concern that pike might escape the lake and enter the Sacramento River system, potentially harming native anadromous fish species such as steelhead and salmon. The effort was controversial because pike are popular gamefish and considerable effort had already been spent on unsuccessful attempts to rid the lake of pike using explosives, nets, shocking, and poison.

Since the 2007 treatment, there have been no confirmed cases of northern pike in the lake.
