Content Purpose: Our main goal is to accurately characterize the migration behavior for these fish, identify potential problem areas in their passage, especially at dams and through reservoirs of the lower Columbia and Snake rivers, and evaluate methods to improve their migration and survival.
Supplemental Information: Taxa: Chinook salmon (Oncorhynchus tshawytscha)Steelhead (Oncorhynchus mykiss)Sockeye salmon (Oncorhynchus nerka)Pacific lamprey (Lampetra tridentata)Chum salmon (Oncorhynchus keta)Methods: Radiotelemetry - Fish used for these studies are primarily collected at Bonneville Dam, the first hydropower project most fish reach during their migration, about 235 km from the mouth of the Columbia River. They are then outfitted with radiotransmitters and transported about 10 km downstream from the dam for release. As these radio-tagged salmon and steelhead migrate upstream, they are monitored using a network of fixed-site radio receivers at dams, near the mouths of tributary rivers, and by mobile tracking by boat and truck. Additional information is gathered from tags returned from hatcheries, crews conducting spawning ground surveys, and from commercial and sport fisheries. Data accessible through this web site have been interpreted by project biologists, both for ease of use and because of the complexity of the receiver array and the database itself. Data have been summarized by placing codes on individual records, each code indicating a particular action (see Data Summary).Dams: Bonneville DamThe Dalles DamJohn Day DamMcNary DamIce Harbor DamLower Monumental DamLittle Goose DamLower Granite DamPriest Rapids DamAgencies Involved: University of Idaho, National Marine Fisheries ServiceStreamNet is a cooperative information management and dissemination project focused on fisheries and aquatic related data in the Columbia River basin and the Pacific Northwest. The project provides a variety of data related to fish resources and maintains the 1:100,000 scale hydrography layer for the Pacific Northwest. Information is available through an on-line database query, interactive maps, direct data download or by custom request. StreamNet receives funding from the Bonneville Power Administration (BPA Project No.: 198810804) and is authorized under the Fish and Wildlife Program of the Northwest Power and Conservation Council. Other organizations provide funding for select project components. Participating agencies contribute significant in-kind services and include: the Oregon Dept. of Fish and Wildlife (ODFW), Washington Dept. of Fish and Wildlife (WDFW), Idaho Dept. of Fish and Game (IDFG), Montana Fish, Wildlife and Parks (MFWP), U.S. Fish and Wildlife Service (USFWS), and the Columbia River Inter-Tribal Fisheries Commission (CRITFC).In addition to the data sets that StreamNet develops and maintains in the central database, StreamNet also provides a service called the "StreamNet Data Store" (http://www.streamnet.org/online-data/datastore.html). The Data Store warehouses data separate from StreamNet's central integrated database, most of which are developed by people outside of the StreamNet project. The data set described here is available from the StreamNet Data Store.
