History

Construction began on the project in 1906 with the building of the main "A" Canal. Water was first made available May 22, 1907. The Clear Lake Dam was completed in 1910, the Lost River Diversion Dam and many of the distribution structures in 1912, and the Anderson-Rose Diversion Dam (formally Lower Lost River Diversion Dam in 1921. The Malone Diversion Dam on Lost River was built in 1923 to divert water to Langell Valley.

A contract executed February 24, 1917, between the California-Oregon Power Company (now the Pacific Power and Light Company) and the United States authorized the company to construct the Link River Dam

 for the benefit of the project and for the company's use, and in particular extended to the water users of the Klamath Project certain preferential power rates. The dam was completed in 1921.

In more recent times, the Klamath Project has been the focus of nationwide controversy. The Lost River

 suckers were listed as endangered in 1988. This, as well as concerns for salmon runs, led to a cutoff of irrigation water to local farmers on April 6, 2001. After many protests by farmers and concerned citizens alike, the decision was reversed the next year.

A massive die off of salmon occurred in 2002 due to low water and high temperatures in the lower reaches of the river during the salmon migration. Studies showed that drought conditions and low flow from the entire drainage were among the factors that caused a unique mix of conditions to allow a gill rot disease to attack the salmon population.

The conflict in balancing the economic and ecological concerns of the region was the focus of the 2006 book River of Renewal: Myth and History in the Klamath Basin. Today, there is still much antagonism between opposing sides on this issue.

Dams

The Klamath Project contains seven dams. These vary from simple earthfill structures to concrete structures several hundred feet high. Three of the seven dams are storage dams, retaining water behind them to be used later. These are the Clear Lake Dam; the Gerber Dam, with Gerber Reservoir; and the Link River Dam

In addition to the storage dams, there are four diversion dams. The Lost River, Anderson-Rose, and the Malone diversion dams are all located on the Lost River

Canals

There are over 717 miles (1,153.9 km) of canal

s, laterals and diversion channels in the Klamath Project. The canals transport irrigation water from Klamath Lake and the Klamath River, Clear Lake and the Lost River, and Tule Lake. There are two tunnels: the "A" Canal (the main canal that starts just above the Link River Dam) has an underground section as it flows through Klamath Falls, and the Tule Lake Tunnel.

There are almost 728 miles (1,171.6 km) of drainage canals in the Klamath Project which allow land that would otherwise be wetlands to be farmed. The Lower Klamath Lake was 80000 acres (323.7 km²) before it was drained and would naturally evaporate about 240000 acre.ft each summer. This is roughly equivalent to the annual delivery of the A canal.

Pumps

There are 28 pumping stations in the Klamath Project. These pumps have a total output of over 1937 ft³/s (55 m³/s).
