  Citation × Citation Citation Abstract Copy Title: Upper Chewaucan Watershed Assessment Abstract -- Several assessment elements have good overall ratings and include the following: riparian vegetation/bank stability, Rosgen stream types, and pool numbers. However, the remaining elements need significant improvement to reach desired levels of high canopy coverage in forested sites, dense juniper woodlands, moderate road densities, lack of LWD, moderate to high stream temperatures, moderate to high spawning gravel fines, and culvert barriers. The less than desired conditions of these elements inhibit the Upper Chewaucan River Watershed from functioning appropriately as a redband trout reserve. As a result, this assessment element is functioning appropriately but-at-risk.

  Citation × Citation Citation Abstract Copy Title: Habrate: A Limiting Factors Model for Accessing Stream Habitat Quality for Salmon and Steelhead in the Deschutes River Basin, 2010. Information Reports Number 2010-03 Abstract -- Fishery managers are commonly tasked with the basic question "Will the contemporary habitat above a barrier support the fish populations that historically resided in the watershed?" Managers in central Oregon were confronted with that question in an effort to reestablish fish populations in 375 kilometers of stream above the Round Butte-Pelton Dam complex (Rkm 161) on the Deschutes River. Stream surveys had been conducted in most of the available stream habitat, but had not been synthesized in a form that allowed managers to view the quality and complexity of stream habitat in an easily-understandable fashion. In response, we developed a limiting factors model (HabRate) that assessed the potential quality of stream habitat using stream survey data for each juvenile life stage of salmon and steelhead. The model was developed for a specific application to the middle Deschutes River basin in Oregon, but was intended for general application to Pacific Northwest basins. To paramatize the model, we summarized available literature on salmonid habitat requirements. Habitat criteria were developed for discrete life history stages (i.e. spawning, egg survival, emergence, summer rearing, and winter rearing) and used to rate the quality of stream reaches as poor, fair, or good, based on attributes relating to stream substrate, habitat unit type, cover, gradient, temperature, and flow. Reach level summaries of stream habitat data were entered into MS Excel, and interpreted by a series of algorithms to provide a limiting factor assessment of potential egg-to-fry and fry-to-parr survival for each reach. Model output lists habitat quality by species and life stage for each reach of stream. The model is a decision making tool that is intended to provide a qualitative assessment of the habitat potential of stream reaches within a basin context. Design criteria for the model were simplicity, flexibility, and transparency. While HabRate was based on our interpretations of the published literature, specific criteria for habitat quality were structured to be easily adjusted where interpretations differ from ours. Information not common to standard stream survey designs, such as seasonal flow or temperature extremes can be included as input from professional judgment. The results were integrated into a GIS coverage coupled with the stream network and habitat data to provide a comprehensive map-based perspective of habitat quality in a watershed.

Electrofishing removal was conducted on 11 reaches and a total of 45 passes were completed. Fifty brook trout were removed. Night-snorkeling was conducted in the five reach, intergrade zone where both bull and brook trout were found. Two comprehenzive passes were completed in the first three reaches, and three passes were completed in the last two reaches. A total of 10 brook trout and 8 brook/bull trout hybrids were removed. Additionally 39 brook trout were removed from a fire pond above Threemile Creek. Mollusk and amphibian surveys were also conducted; and temperature was collected in the Threemile Creek Project Area.
