Natural Propagation and Habitat Improvement, Volume I, Oregon, Supplement C, White River Habitat Inventory, 1983 Annual Report
More than 130 miles of stream fish habitat was inventoried and evaluated on the Mt. Hood National Forest during the first year of this multi-year project. The number of stream miles somewhat exceeded the original target. Inventory, data evaluation and reporting work were accomplished within the original budget established in BPA/USFS Agreement No. DE-A179-83BP 13992, White River Habitat Inventory, Project No. 83-440. All objectives of FY '83-84 project were met or exceeded within time and
... thin time and budget limits agreed upon with B.P.A. Summary tables, included in Section II of this report, and individual stream reports, Sections III, IV, and V, present findings of this year's inventory. X 1 METHODS The assessment was conducted by two, two-men teams. The teams gathered a variety of information (spawning gravel, rehab/enhancement projects, special habitats, and fish numbers) on a continuous basis while walking the streams. Additional, more detailed information (flow, channel morphology, pool/riffle measurement, riparian area conditions, etc.), was gathered at transects located approximately every 1/2 mile of stream. Lower portions of major tributaries were also surveyed. (A copy of the field data reporting forms is included at the end of this introductory section.) For certain situations (fish passage barriers, tributary streams, landslides, etc.), special case forms were completed. Semi-quantitative models, developed on the Mt. Hood National Forest, have been used to provide a quality index for both fish habitat and riparian habitat. These indexes rate hahitat quality on a 0 (poorest) to 10 (best) scale. To date these models have not been field verified. They are, however, intended to be used as tools to assist in project planning, helping to identify and discuss limiting factors and/or areas of concern. X 2 REPORTING FORMAT The emphasis of this report is on summarizing and interpreting pertinent data. The goal is to provide information which is understandable and easy to locate by a wide range of users. Section II contains five tables which summarize basic anadromous fish habitat conditions for all streams evaluated this year. Additionally, a drainage map has been included to graphically reflect anadromous habitat conditions. The indi vidual report s for each stream are broken into three basic sect ions, represen ting di fferen t levels of summar ization and interpreta tion. The se are: 1) The general summary section (blue pages). Here the most Pertinent aspects of the information are generalized to provide a good basic overview of each stream's riparian area resources. 2) The second section (yellow pages), which is a more detailed summary of various resource conditions by reach of stream. Summaries include: reach characteristics; aquatic habitat conditions; riparian area conditions; and rehab/enhancement project opportunities. 3) The third section (white pages), which includes a wide range of detailed resource data. This is organized into a number of information tables. These include: aquatic habitat parameters; spawning gravel; fish species and relative abundance; stream channel and hydrologic characteristics; floodplain and riparian area parameters, etc. In addition, a stream order map, selected photos, a detailed assessment area map, and special case forms are included. FUTURE WORK Habitat inventory work, using FY '83-84 procedures, will occur on 40-60 miles of additional White River tributaries. These streams are believed to offer relatively less potential for anadromous fish production than those examined during the first year. Additionally, intensive transect sampling of selected habitat parameters will also likely occur on various sample stream reaches.
