Abstract
  • The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by reductions in amount of spawning gravel available at preferred water depths and velocities. Minimum discharge recommendations are specified that will meet fish requirements. Data are presented on stream discharge; water quality; gravel bar distribution, size, and composition; recreational usage; trout and salmon spawning numbers, distribution, and embryo survival; water flow over spawning gravels and fish preferences; and the intragravel environment of spawning beds including the dissolved oxygen content of intragravel water, gravel permeability, and intragravel water temperatures.
  • This is a report of data and observations gathered during the Lower Deschutes Flow Study. The authors describe the area’s geography, topography, and geology. The work covers Deschutes River stream discharges and regulations, as well as its biological contents. It continues with a focus on salmonid spawning, including a study of water flow over spawning gravels, dissolved oxygen, gravel permeability, and temperatures for water around spawning beds. There are extensive maps, charts, tables, and photographs.
