| C | 78877 | 158 | Mark/Tag Animals | Determine Bull Trout Life History Type (Fluvial or Resident) In Warm Springs River & Shitike Creek | We will determine bull trout movement patterns in Warm Springs River and Shitike Creek to determine life history type by implanting 50 juveniles each in the Warm Springs River and Shitike Creek with half duplex Passive Integrated Transponder (PIT) . Movements will be monitored using established PIT tag readers in Warm Springs River and Shitike Creek. Under optimal conditions, all females would retain PIT tags and multi-year spawners would be included in the analysis. However, we expect shedding of PIT tags to be minimal and not effect the outcome of the experiment. Surgical procedures are based upon University of Idaho techniques. | $3,954 | 3.04% | 10/01/2010 | 09/30/2011 |
| D | 75840 | 157 | Collect/Generate/Validate Field and Lab Data | Collect Movement Data From Warm Springs River PIT Arrays | Since 1983, only ten juvenile bull trout have been captured through migrant trap (Humphrey trap and rotary screw traps). The low numbers of bull trout may be indicative of low capture efficiencies; however, it may also be because some bull trout in the Warm Springs River display a resident lifestyle. Also, low numbers of adults immigrating through the Warm Springs National Fish Hatchery compared with the higher number of fish passing through the Warm Springs Meadow weir suggest resident forms.
To further document bull trout movements between and within the Warm Springs River, Deschutes, and Shitike Creek, 150 juvenile bull trout have been tagged with half duplex (HDX) passive integrated transponders (PIT). Movements are currently and will continue to be monitored through established PIT tag readers in Warm Springs River and one to be developed in Shitike Creek. Under optimal conditions, females retain PIT tags and multi-year spawners will be included in the analysis. However, we anticipate minimal PIT tag shedding.
Two half duplex (HDX) passive integrated transponder (PIT) arrays have been developed in the Warm Springs River system. One at the mouth of the Warm Springs River and another near the Warm Springs Meadows. These arrays will be used to evaluate long-term movement patterns bull trout in the Warm Springs Watershed to determine if a portion of the population displays a resident life history.
We previously had installed an array at the Warm Springs National Fish Hatchery, however, this array has been experiencing technical difficulties and will need further attention to be completely operational in 2011. | $34,546 | 26.56% | 10/01/2010 | 09/30/2011 |

The site will be developed near the confluence of the Deschutes River and Shitike Creek, in Shitike Creek. | $13,698 | 10.53% | 10/01/2010 | 09/30/2011 |
| F | 75841 | 157 | Collect/Generate/Validate Field and Lab Data | Monitor Juvenile Bull Trout Abundance & Habitat Use In Warm Springs River Through Night Snorkeling | Monitoring the abundance and distribution of juvenile bull trout within a stream is essential to assess the status of a given population. However, due to limited resources and access difficulties, many bull trout populations are monitored by sub-sampling portions of juvenile rearing habitat. From 1999 - 2009, juvenile bull trout have be enumerated in a 2.4 km reach of the Warm Springs R. and compared with counts from four established “index” reaches within the 2.4 km reach. The 2.4 km contains approximately 90% of the summer time juvenile rearing area. Relative densities within the individual index reaches have differed from the densities within the 2.4 km study area. When index reaches are combined, representing 22% of the 2.4 rkm study area, the relative densities for both juvenile bull trout and brook trout within the combined reaches are comparable to the densities observed in the 2.4 km study area. | $3,267 | 2.51% | 10/01/2010 | 07/31/2011 |

| H | 75843 | 157 | Collect/Generate/Validate Field and Lab Data | Monitor Juvenile Bull Trout Abundance In Shitike Creek Through Night Snorkeling | Bull trout require complex stream habitat and cold water temperatures (<15° C) during the juvenile rearing life stages (Dambacher and Jones 1997; Fraley and Shepard 1998; Ratliff 1992; Reiman and McIntyre 1993). Juveniles rear in streams three or more years (Ratliff et al. 1996, Pratt 1992). They are dependent on high quality stream habitat. During the juvenile stage, bull trout are considered benthic to take advantage of the substrate interstices for cover, food and protection (Buchanan et al.1997). Availability of juvenile rearing habitat may limit bull trout distribution. | $2,878 | 2.21% | 10/01/2010 | 07/31/2011 |

| J | 75852 | 157 | Collect/Generate/Validate Field and Lab Data | Monitor Juvenile Bull Trout Abundance and Distribution In Whitewater River | Monitoring the abundance and distribution of juvenile bull trout within a stream is essential to assess the status of a given population. Bull trout require complex stream habitat and cold water temperatures (<15oC) during the juvenile rearing life stage (Fraley and Shepard 1998, Ratliff 1992). Juveniles rear in streams for two to three years or longer, therefore depend on high quality stream habitat for a major portion of their lives (Ratliff et al. 1996, Pratt 1992). Land management activities (e.g., timber harvest) and natural environmental disturbance (e.g., fire, flood, debris flows) may affect quality and quantity of rearing habitat over time (Hicks et al. 1991).
Whitewater Basin is remote and access into the river is challenging, therefore habitat and fish data are scarce. A juvenile bull trout distribution survey in Whitewater River was conducted in 1998 (Brun 1998). This survey will be repeated and results compared. The last habitat survey was also done in 1998 by ODFW. However, a recent fire in the Whitewater watershed was reported to have caused some bank erosion.

| L | 75845 | 157 | Collect/Generate/Validate Field and Lab Data | Deploy Thermographs In Warm Springs River & Shitike Creek | Water temperatures have limited bull trout distribution within some drainages (Reiman and McIntyre 1993; Fraley and Shepard 1989; Howell and Buchanan 1992). Bull trout require cold water for a significant portion of their lives. Bull Trout juveniles are largely absent in streams with water temperatures exceeding 15°C. Adults commence spawning when water temperatures are below 10°C. However, little is known about adult temperature tolerances during migration and pre-spawning holding periods (Buchanan and Gregory 1997; Shepard et al. 1984; Goetz 1989). Tribal, federal and state agencies have promulgated rules to protect water temperatures in streams containing bull trout and other salmonids. However, these temperature standards have not been evaluated as to their effectiveness for protecting bull trout in the lower Deschutes River. Our objective is to conduct long term water temperature monitoring in Shitike Creek and the Warm Springs River to determine the annual range of water temperatures associated with tributary entry, migration and holding, and spawning and rearing. | $2,729 | 2.10% | 10/01/2010 | 09/30/2011 |

| N | 75847 | 157 | Collect/Generate/Validate Field and Lab Data | Use A Video Weir To Enumerate Adult Bull Trout Moving Into Spawning Areas In The Warm Springs | Majority of bull trout in the lower Deschutes basin exhibit a fluvial life history pattern. Adults return to their natal streams to spawn beginning at age IV. Bull trout are fall spawners, with onset typically beginning in September and commencing in late October, early November (McPhail and Murray 1979, Shepard et al. 1984). Spawning has been observed in August in tributaries of the Metolius and Deschutes Rivers (Ratliff 1987; Brun 1999).
A weir, equipped with an underwater video camera system, was placed downstream of the bull trout spawning grounds in the Warm Springs River (Rkm 52.0) during 2002. | $5,063 | 3.89% | 10/01/2010 | 09/30/2011 |

| P | 75849 | 157 | Collect/Generate/Validate Field and Lab Data | Conduct Redd Counts In The Warm Springs River & Shitike Creek | Bull trout require cold water, complex instream habitat, and clean gravel for successful spawning. They spawn during the fall when the availability of cool water is limited in most streams. As a result, there is only a small amount of suitable spawning habitat available in most streams (Fraley and Shepard 1989). Identification and protection of spawning areas is crucial for preservation of this species.
Annual redd counts within index reaches are widely used to monitor trends in bull trout abundance throughout their range (Sanborn et al. 1998). Prior to establishing index reaches, basin-wide spawning surveys should be conducted to locate bull trout spawning areas. The surveys, repeated throughout the spawning period, are necessary to determine the specific locations, timing and duration of spawning. Information obtained from basin-wide surveys may be used to determine if a sub-sample of the known spawning habitat, i.e., index reaches, may be used to reliably monitor spawning abundance within a particular stream. | $2,617 | 2.01% | 10/01/2010 | 09/30/2011 |
