Province Summary


Columbia Upper Subbasin Summary

Major tributaries within the Upper Columbia Subbasin include the Colville and Kettle rivers and Big Sheep Creek. Significant lakes within the Subbasin include Loon, Waitts, Williams, Cedar, Deep, and the lakes of the Little Pend Oreille chain. Lakes of importance to the members of the Colville Confederated Tribes (CCT) include the following; North and South Twin, Owhi, Omak, Buffalo, Round, LaFleur, Nicholas, Borgeau, and Sugar lakes, and on the north half of the former reservation, Ellen, Elbow, Pierre, and Summit lakes.

Grand Coulee Dam regulates Lake Roosevelt water levels between 1,208 level (minimum pool) and 1,290 feet mean sea level (full pool). The reservoir extends a total of 135 miles (217 km) upstream (USGS 2004), covers 82,300 acres, and stores approximately 9,562,000 acre-ft of water. When the reservoir was initially filled to full pool, over 70,000 acres of land was inundated. The watershed area that comprises the Subbasin is approximately 2,411 square miles and includes 226 tributaries to the Reservoir (excluding the Spokane River, San Poil River, Colville River, and Kettle River).

Many different land uses exist within the boundaries of the Subbasin including cattle grazing, crop production, mining, and timber harvest. Overall the Subbasin is sparsely populated, although many urbanized areas exist. A variety of land uses occur within the lands within the Columbia River Valley between Grand Coulee Dam and the U.S.-Canadian border. Agriculture, mining, timber harvesting, ranching, and urban uses all occur within the various counties that are adjacent to Lake Roosevelt. Dry land farming of barley and wheat are common to the south of the lake. Lincoln County is the nations second largest producer of wheat. In addition, lumber and pulp operations are present within the area, which stem from the local timber industry. Although the area is not densely populated, up to 1.5 million people visit Lake Roosevelt to recreate each year.

Limiting Factors in the Columbia Upper Subbasin 408

Burbot
Key Limiting Factor Impairment Habitat Affected Threat Type Threat Name Life Stage(s) Description
Habitat Quantity and Quality Small-scale structural complexity; Morphological changes Freshwater Dam and hydropower facility management Water: Storage or withdrawal Juveniles, adults Severe fluctuations of reservoir elevation frequently changes the littoral zone, limiting productivity. The lack of stable littoral habitats has resulted in virtually no macrophyte communities and severely depressed benthic macroinvertebrate communities.
Instantaneous Mortality Predation - Fishery management Species introductions Juveniles and adults Walleye and smallmouth bass introductions have lead to community shifts and predation issues.
Toxic Vontaminants Water: Biota - Mining Activities; Pollution and Contamination Pollution: Heavy Metal; Pollution: Biological Wastes, Fertilizer, & Pharmaceuticals All Trace-element contamination is known to be widespread throughout Lake Roosevelt. recent studies report that Lake Roosevelt bed sediments are contaminated with high concentrations of trace elements, and that these high levels are impairing benthic invertebrate communities. The trace-elements have been linked to a smelter in Canada.
Water Quality Oxygen - Dam or hydrofacility management Water: Temperature and gas alteration Juveniles; adults Spillling at upriver reservoirs creates total dissolved gas levels in Lake Roosevelt that exceed state standards.
Water Quantity Altered flow timing - Dam or hydrofacility management Water: Storage or withdrawal Juveniles and adults The most significant limiting factor affecting fish in Lake Roosevelt is pool elevation fluctuations that result from hydro-operations. Due to a short water retention time (8-65 days), there is a lack of stratification during the summer that results in limited refugia of preferred temperature areas. Hydro-operations that reduce water retention time also reduce food availability for fish and reduce fish carrying capacity of the reservoir.
