Book excerpt: Excerpt from Survey of the Columbia River and Its Tributaries Part V, Vol. 38: Special Scientific Report: Fisheries No; 38 The purpose of the Columbia River Stream Survey has been to provide data for the evaluation of each stream, or portion of stream, from the standpoint of its present and potential value in relation to the maintenance of the salmon resources of the Columbia River. The Columbia River watershed has been divided into several survey areas or units. This report deals with the streams in Area IV, as shown in Figure 1. Area IV includes all tributaries entering the Columbia River from the south and east in the 120 miles from the Deschutes River up to but not including the Snake River Area IV has been divided for convenience into two sub-areas; Part 1 of this report covering the Deschutes and John Day river systems, and Part 2 the Umatilla and Walla Walla river systems. All of Area IV is east of the Cascade mountain range, and includes a large amount of arid and semi-arid land. The diversion of large quantities of water for irrigation purposes has greatly reduced the sustained flows in the tributary streams This factor together with the obstructions placed in the streams as a part of the irrigation facilities and the hazards to downstream migrating fingerlings resulting from unscreened diversions have adversely affected the production of salmon and trout.
