Furthermore, the lake is a recreation area in summer and in winter. In winter the water level is lowered to make room for high water that usually comes in the spring. In summer, water is discharged to supply the river with adequate quantities of water for the fish.

Mossyrock is also the name of a nearby city, which has been newly built on the site perished in the lake villages reefs and the cosmos. The former name Davisson comes from an engineer who supervised the project, but the reservoir was soon renamed in honor of the city reefs. Reefs as " life" pronounced. " Rifle Lake " is probably a misspelling, which indicates a not properly understood meaning.
