ApplicationInformation and Examples on Applying Stream Survey DataStream survey summary data can be used to query the range of habitat conditions by stream reach. These habitat conditions vary considerably between streams; stream differences relate to past and current management activities, geology, elevation, aspect, climate and numerous other variables influencing watersheds, stream channels and floodplains. Stream survey data in comparable watersheds and stream valleys can be used to develop benchmarks or ranges of conditions anticipated in reference streams. This is useful for contrasting current conditions with reference conditions. This can aid in determining dominant processes operating in the watershed and assist with development of restoration strategies that address the present gaps between historic and current conditions in watersheds.

Three matrices used for project consultation for listed fish species and critical habitat in three separate geologic provinces in SW Oregon are included here as: These matrices are used for the Klamath/Siskiyou Geology, High Cascades Geology and Tyee Sandstone Geology respectively. Steam and riparian habitat attributes that can be ascertained from the stream survey data are marked in yellow highlight in each file. These matrices were developed locally and are used by biologists and hydrologists in the three major geologic areas of Southwest Oregon. ODFW Benchmark is a set of Benchmark Values created by the Oregon Department of Fish and Wildlife to assess the condition of streams using stream survey attributes. Sucker Water Quality Plan is an example of stream survey data used to assess the condition of a stream in a Water Quality Management Plan. Sucker Creek and Grayback Creek are listed under the Clean Water Act -303(d) for habitat modification. Benchmarks were established based on Forest data and the ODFW benchmarks for Western Oregon with some adaptations noted. GraphsBar graphs created in PowerPoint are a good way to display stream survey data at the reach scale. Wood Pools Summary contains five vertical bar graphs that summarize attributes collected from stream surveys by reach: small, medium and large wood per mile, pool area by reach, pools per mile by reach and the frequency of pools using bankfull channel widths to normalize for stream size. These types of graphs can be used to develop numeric ranges for stream reaches. Stratifying by management intensity, watershed size, geology, elevation and other attributes can be useful for developing a natural range of variability for instream wood, pool frequency, percent pool area, riparian seral stage, width depth ratios and other attributes collected in stream surveys. ^^ Back to Top Query for Pool Frequency and Large Wood The file entitled Pool Wood Sort is an example of a specific query in SMART. Survey data from before 1996 was queried to summarize and compare characteristics of stream reaches with gradients equal to or less than 3%. These lower gradient stream reaches were found to be more depositional in nature, were less confined, usually contained salmon, coho salmon are listed under ESA, and were pool/riffle morphology. Pool frequency, substrate, valley confinement and large wood were among the attributes displayed by reach. Fish Census Spreadsheets Stream surveys can be used to collect general juvenile fish numbers and SMART is adaptable to storing the information. On many Forests, force account crews or contractors are required to do single pass snorkel counts in each nth unit or at more frequent intervals. The "D" Fish Form can be adapted to tally not only the numbers of fish by species (also amphibians and reptiles) and also the relative age of these fish. This information is tallied on the D Form as text characters. The file Sugar_Fish.lst is directly exported from SMART by doing a query. This is an ASCII file with question marks (?) delimiting the characters. The NSO, habitat type, species of fish and the count by age class is shown. Typical age class lengths can be developed for each stream to determine the size differences between young-of-the-year, age one and age two and older fish. This is documented in the comments section of the stream survey, so follow-up fish census work is consistent in the method of segregating fish by age and species. Sugarpine Fish shows the ASCII file imported into MS-Excel and columns placed to separate the delimited file. Sugarpine coho counts summary is an example of how one can take similar information over several years and develop graphs showing juvenile fish density trends. In this case, coho juveniles in pools were counted in two sub-watersheds were used over a three-year period to show the relationship between juvenile coho salmon densities in pools in two sub-watersheds (Bitterlick and Sugarpine Creeks) and the total escapement of adult coho salmon into the watershed (Elk Creek) through a trap and haul facility near the mouth.
