In 2000, the Department of the Interior (DOI) purchased Elwha and Glines Canyon dams, impounding the Aldwell and Mills Reservoirs on the Elwha River in Washington State. These two dams are to be removed to support river habitat restoration. Approximately 24 million cubic yards of sediment are being managed as part of the dam removal project. Monitoring shifting topography that occurs as the sediment is eroded and redistributed downstream is critical for adding to the science of dam removal. Reclamation partnered with the U.S.
The Klamath Reclamation Project was initiated in 1906 to provide irrigation water and irrigable land in the Klamath Basin, Oregon. As part of these efforts the “A” Canal was built through the City of Klamath Falls and was completed in 1907. Since that date, the City of Klamath Falls has grown considerably with a concurrent increase in the amount of impervious surface. These impervious surfaces have led to increased run-off, which has been directed into the “A” Canal. This has created a conflict as this canal was never designed to accept run-off in addition to moving irrigation water. A
The Bureau of Reclamation routinely monitors more than 3.5 million acres of agriculture and riparian vegetation along the Lower Colorado River from Hoover Dam to the Southerly International Boundary. Data generated include crop and riparian types, acreages, and associated water use estimates. Remote sensing and Geographic Information Systems (GIS) are the primary tools used for this activity. These data assist Reclamation in accounting for water use by each state and individual water user, verifying fallowed lands for conservation programs, and other water management analysis needs.
Reclamation is charged with measuring consumptive water use (water that is removed from a watershed) within the Colorado River Basin. Irrigated agriculture accounts for the majority of consumptive use, and historically Reclamation has combined estimates of crop acreage with local weather and crop development information to estimate seasonal consumptive water use by agriculture. But actual water use can decline from reference values due to crop stress caused by salinity problems, damage due to pests or disease, or water shortage.
Reclamation is responsible for administration of the Operating Criteria and Procedures (OCAP) for the Newlands Reclamation Project in Nevada.
The San Joaquin River Restoration Program is a comprehensive long-term effort to restore flows to the San Joaquin River in California’s Central Valley from Friant Dam to the confluence of the Merced River. The goal is to restore a self-sustaining Chinook salmon fishery in the river while reducing or avoiding adverse water supply impacts from restoration flows. Reclamation continues to investigate and develop remote-sensing-based methods to map and monitor vegetation and its response to flow restoration on the river.
