Kvichak Spawning Ground Catalog

Information about the red salmon runs and the spawning streams and beaches in the Kvichak River system, Bristol Bay, Alaska, is cataloged in this volume. The material is compiled from data obtained from spawning ground surveys made in the area since 1955 by the Fisheries Research Institute of the University of Washington. Earlier work was financed by the salmon canners of Bristol Bay. In recent years the work was supported by the Bureau of Commercial Fisheries.For each spawning stream or beach, the catalog gives, whenever available, the stream catalog number, name, location, and physical description including dimensions, bottom quality, flow, barriers, etc. Then a description of red salmon runs to the area is listed, including magnitude of the run and timing and distribution of spawning. Estimates of numbers of red salmon to each stream or beach are listed chronologically under a separate entry entitled “Summary of Surveys.”

Wood River Spawning Ground Catalog

Information on the red salmon runs to all the major spawning tributaries in the Wood River lake system, Bristol Bay, Alaska from 1946 to 1962 is cataloged in this report. The Wood River lake system comprises a chain of four main lakes with their tributary lakes and creeks. The order of presentation is from lower to upper lakes and, within each lake, from the lake outlet around the lake in a clockwise order. A trunk stream or connecting river is considered with the lake from which it drains. Included are 47 creeks, 11 belonging to Lake Aleknagik, 17 to Lake Nerka plus 3 to Little Togiak Lake which empties into Lake Nerka, 11 to Lake Beverley, 1 to Lake Mikchalk, and 4 to Lake Kulik.

For each creek, there are three main entries. First, the catalog number, name, location, and physical description (which includes creek dimensions, potential spawning areas, bottom quality, flow, air and water temperatures) are given. On the following page some cardinal points about the red salmon runs, including the average percentage of the total escapement, escapement range, time and peak of spawning, and distribution of the spawners, are given. Finally, a summary of surveys lists chronologically the estimated numbers of red salmon.
