  • Environmental Conditions Appendix II
    Environmental Conditions Environmental Conditions Appendix II The unique geology, hydrology and climates of the Deschutes River Subbasin create a diverse mix of habitat conditions for fish and wildlife. These populations are linked to the ecosystems in which they live and their health, individual characteristics and abundance reflect the diversity ― and quality ― of their environments. Fish populations, for instance, developed complex life histories through time that responded to the subbasin’s considerable variation in habitat conditions. Stream flows, water temperatures, substrate characteristics and other combined attributes affected anadromous fish distribution within the subbasin and timing of migration. Wildlife population abundance and distribution also developed in response to habitat conditions. Native grasslands once covered vast areas and supported species such as sage grouse, which once occurred exclusively in this habitat. Loss of grassland habitat greatly reduced such populations. Today subbasin habitat conditions continue to influence fish and wildlife production, distribution and survival. These habitats and their attributes ― as well as the aquatic and terrestrial populations they support ― are affected by both natural watershed processes and human activities that influence flow, water quality, upland and riparian conditions and instream habitat. This chapter examines how environmental conditions in the Deschutes watershed affect the subbasin’s fish and wildlife populations. Building on the more general review provided in the Overview, the discussion characterizes the environmental conditions within three watershed areas: the Lower Deschutes watershed (below RM 100), Crooked River watershed, and Upper Deschutes watershed (above RM 100). It characterizes the natural watershed environments, such as geology, climate and hydrology, and the focal fish species they support.

    ODFW AQUATIC INVENTORY PROJECT STREAM REPORT STREAM: Metolius River LLID: 1212861445954 BASIN: Deschutes River HUC NUMBER: 17070301 DATES: June 21 - July 14, 2011 SURVEY CREWS: Frank Drake / Mark McLaughlin REPORT PREPARED BY: Staci Stein USGS MAPS: Black Butte, Candle Creek, Prairie Spring Farm ECOREGION: Cascade Eastern North BASIN AREA: 795 km2 FIRST ORDER TRIBUTARIES: 50+ GENERAL DESCRIPTION: The Metolius River habitat survey began at the confluence of Jefferson Creek and continued upstream 21,049 meters to end at the headwater springs surfacing from the hillside. Nine reaches were designated based on changes in channel morphology and contributions from major tributary junctions. The river channel was constrained by terraces and hillslopes. Land uses were mature trees (50-90cm dbh), large timber (30-50cm dbh), rural residential property, and second growth timber (15-30cm dbh). The crew floated the river with inflatable kayaks in the lower reaches (Reaches 1-4) where the river was too swift and deep for safe and accurate measurements by foot. The upper reaches (Reaches 5-9) of the river were surveyed by foot. Overall stream substrate was a combination of gravel (36%), sand (24%), cobble (18%), and silt and organic fines (11%). The stream habitat types were predominately riffles (50%), scour pools (28%), and rapids (14%). Large wood debris volume ranged from 1.5-17.8m3/100m. The trees observed most frequently in the riparian zones were conifers ranging from 3-50cm dbh (based on thirty-one riparian transects). REACH DESCRIPTIONS: Reach 1: (T12S-R09E-S02NE) Length 3029 meters. Reach 1 began at the confluence with Jefferson Creek and continued to Bridge 99.

  • Life History, Population Dynamics, and Management of Signal Crayfish in Lake Billy Chinook, Oregon
    ANABSTRACT OFTHE THESIS OF Scott D. Lewis for the degree of Master of Science in Fisheries Science presented on 24 November 1997. Title: Life History, Population Dynamics, and Management of Signal Crayfish in Lake Billy Chinook, Oregon. Abstract approved:Signature redacted forprivacy. / '- 1 Howard F. Horton Signal crayfish Pacifastacus leniusculus were studied in Lake Billy Chinook, Oregon, during 1994 and 1995. Because little was known about the crayfish population, this study was conducted to obtain reliable estimates of life history and population parameters, document historic commercial harvests, and make management recommendations. Crayfish were captured with baited traps and by hand using SCUBA gear. Maturation of both male and female crayfish occurred during the fall of their third year at age 2+. Copulation of mature crayfish began during the first week of October in 1994 and 1995. In 1995, hatching began during the second week of April. The estimated mean days and thermal units required for egg incubation was 166 days and 2,208 degree-days, respectively. Mean pleopod fecundity during the incubation period was 105 ± 12 (mean ± 95% CI) eggs. Crayfish were captured as deep as 100 m, but 98% of the population was found at depths70 m. The peak relative abundance of crayfish occurred at 10-20 m. Diel activity of crayfish was primarily nocturnal and was skewed towards sunset. Eight age classes were identified from analyses of length-frequency distributions. The sex composition of crayfish appeared to be a 50:50 ratio and only deviated because of behavioral changes related to hatching. The mean density of crayfish, estimated from transects, in five habitat types ranged from 0.24 crayfish/m2 to 1.13 crayfish/rn2.

  • Crooked River Restoration
    9/27/2019 Crooked River ‐ Native Fish Society Region: Oregon District: Mid-Columbia Summary The Crooked River, in central Oregon, is a large tributary to the Deschutes River. It runs for approximately 155 miles and the basin drains nearly 4,300 square miles. Native Species Spring Chinook Salmon Summer Steelhead Redband Trout Bull-trout-esa-listed The Crooked River The Crooked River has three major headwater tributaries, the North Fork, South Fork, and Beaver Creek which join to make the mainstem as it flows through Paulina Valley. Further down, Bowman Dam, creates Prineville Reservoir. Below Bowman, eight miles of the river are designated Wild and Scenic as it traverses a steep desert canyon. In Prineville it is joined by Ochoco Creek, soon to collect McKay Creek and several smaller tributaries. It empties into Lake Billy Chinook, a large impoundment on the Deschutes created by Round Butte Dam. This dam inundates nine miles of historic river channel. The Crooked River and its tributaries were once a major spawning ground for anadromous fish such as spring Chinook Salmon, Steelhead trout, and Pacific lamprey. Non-migratory fish such as Redband trout and Bull trout, as well as various non-game fish were also abundant. Fish populations began to drop in the early 19th century due to irrigation withdrawals. https://nativefishsociety.org/watersheds/crooked‐river 1 9/27/2019 Crooked River ‐ Native Fish Society The Cove Power Plant on the lower Crooked River, built around 1910, effectively blocked upriver migration of spring Chinook salmon during low stream flow conditions. In addition, Ochoco Dam, built in 1920 on Ochoco Creek, blocked fish passage completely.

  • Greater Bend Community Wildfire Protection Plan
    Greater Bend Community Wildfire Protection Plan Two Bulls Fire, June 2014 February 2016 Prepared by Project Wildfire 541-322-7129 www.projectwildfire.org [email protected] ª Executive Summary Community Wildfire Protection Plans (CWPPs) are documents that are designed by a local group of stakeholders who are invested in the wildland fire threat to their area. The group of stakeholders typically consists of a representative from the fire department(s), the state, any governing bodies and especially property owners. Each of these representatives should bring their concerns regarding wildland fire to the discussion and propose solutions to their concerns. Although reducing the risk of high intensity wildland fire is the primary motivation behind this plan, managing the larger landscape to restore forest health and more resilient conditions and improving fire response by all fire agencies are also discussed and addressed in the action plan. Continued efforts have been made by county, state and federal land management agencies to reduce the threat of high intensity wildland fires through education and fuels reduction activities on public lands. In addition, private property owners have responded enthusiastically to the defensible space and preparation guidelines and recommendations to reduce hazardous fuels on their own properties by participating in programs such as Firewise and FireFree. All of these activities allow the Greater Bend Area to become a more Fire Adapted Community. Wildland fire is a natural and necessary component of ecosystems across the country. Central Oregon is no exception. Historically, wildland fires have shaped the forests and wildlands valued by residents and visitors. These landscapes however, are now significantly altered due to fire prevention efforts, modern suppression activities and a general lack of large scale fires, resulting in overgrown forests with dense fuels that burn more intensely than in the past.
