Biological Opinion and Canadian Storage ESA requirements have increased interest in Canadian storage for U.S fishery needs Canada and U.S. have worked together in recent years to develop mutually agreeable operating agreements to use Treaty and non-Treaty storage to meet non-power requirements in both countries Examples include Nonpower Uses Agreement which provides for 1 Maf of flow augmentation storage for U.S. in exchange for improved flows in Canada for whitefish and trout
Libby and Kootenay River Operations Libby operates to support multiple fishery requirements including white sturgeon, bull trout, salmon, and burbot For example, in MAF of water will be released from Libby for endangered sturgeon in the Kootenay River. Releases help meet temperature attributes (warmer water) at Bonners Ferry for sturgeon spawning Sturgeon operation ends about June 23 Reservoir will likely fill to within 11 feet of full by end of June Reservoir potentially drafted in July and August to 2,439 (20 feet below full) by end of August for flow augmentation for downstream salmon.
Summary Increased demand for water resources for fisheries and other requirements makes coordination and integrated planning and operation more essential Collaboration between U.S. and Canada to maximize benefits of the Columbia River has tremendous value to both countries Columbia River Treaty has proven to be a very effective basis for collaboration between the two countries to achieve mutual benefits
