Klamath Project

Of that total, 80,000 acres (32,000 ha) were recovered by draining a portion of Lower Klamath Lake, a shallow marsh straddling the Oregon-California border between the California towns of Dorris and Tulelake.

The Malone Diversion Dam on Lost River was built in 1923 to divert water to Langell Valley.

[2] A 2002 report by the National Research Council however, determined that the decision to stop delivery of irrigation water in 2001 was not scientifically justified and that the 2002 fish kill was caused by a combination of natural factors.

[3] 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.

In chronological order of completion, they are: There are over 717 miles (1,154 km) of canals, laterals and diversion channels in the Klamath Project.

There are almost 728 miles (1,172 km) of drainage canals in the Klamath Project which allow land that would otherwise be wetlands to be farmed.

The Lower Klamath Lake was 80,000 acres (32,000 ha) before it was drained and would naturally evaporate about 240,000 acre-feet (300,000,000 m3) each summer.

The Bureau must consider water needs for threatened coho salmon in the river, and two species of endangered sucker fish in Upper Klamath Lake.

[8] Downstream populations of Coho salmon are within the Southern Oregon/Northern California Evolutionary Significant Unit and are listed as threatened (2011).
