Modern Lake Lahontan is a reservoir on the Carson River in northwest Nevada in the United States.
It is formed by the Lahontan Dam, built in 1905 by the Bureau of Reclamation as part of the Newlands Reclamation Act and is located between Fallon, Nevada and Carson City, Nevada. The flows from the Carson River are augmented by the diversions from the Truckee River. The reservoir is maintained by the Truckee-Carson Irrigation District (TCID). The lake is named after ancient Lake Lahontan, which covered much of northwestern Nevada during the last ice age.
Lake Lahontan is 17 miles (27 km) long and has 69 miles (111 km) of shoreline. It consists of several lobes connected by narrow straits. When full, it has approximately 10,000 acres (40 km2) of surface area, although it is usually less than half full by late summer.As no water rights have been allocated for recreation, the TCID could completely drain the lake to supply its irrigation customers. Submerged beneath the water were parts of stagecoach routes which existed during the 1800s including Williams Station, the scene of the Battle of Williams Station, a minor skirmish during the Paiute War.
The lake sits within the Lahontan State Recreation Area. Recreational uses include fishing, pleasure boating and camping. Much of the shoreline is sandy and makes for good camping. As it is contaminated with mercury from the Comstock and other mines, consumption of fish from the lake should be limited as per posted guidelines.
Primary game fish include wipers (white bass x striper hybrid), white bass, walleye, channel catfish, white catfish, largemouth bass, spotted bass, and crappie. It is stocked with walleye fry and fingerling wipers nearly every year. The best fishing occurs from April through July and October.
