As a consequence of severe habitat degradation in the SFSR and the simultaneous effects of hydroelectric development on the Snake and Columbia rivers, the population declined severely. The fishery for steelhead trout has been closed since 1968 in an attempt to sustain the remaining population. In 1984, we began evaluating the status of wild SFSR steelhead and resident trout by collecting information on principal spawning areas; classifying spawners; evaluating relative abundance, density and distribution of fish in rearing areas; monitoring movements; evaluating genetic qualities; and surveying angler effort and harvest in the SFSR. We found a viable wild population of steelhead trout in the SFSR drainage. The fish appeared to be most similar to "B-stock" steelhead and averaged 85 cm total length. A total of 407 redds were counted representing a minimum of 485 adults. Spawning commenced in mid-April and extended to the end of May. Approximately 70% of the spawning was observed on the mainstem SFSR with the remainder in tributaries. Juvenile steelhead trout (parr) rear in the mainstem SFSR and tributaries. Densities averaged 1.0 parr per 100 m2 in the mainstem, 2.1 parr per 100 m2 in the East Fork of the South Fork, and 2.6 parr per 100 mL in 10 other tributaries. Juvenile steelhead comprised 93% of the age I and older salmonids in the mainstem SFSR and 76% of the fish in tributaries. Preliminary electrophoretic analysis data suggest that SFSR wild steelhead trout may be genetically isolated from Middle Fork Salmon River steelhead trout stocks. Westslope cutthroat trout (Salmo clarki lewisi) comprised 3% and 2%, respectively, of the age I and older salmonids in the mainstem SFSR and tributaries. Most (80%) of the cutthroat trout in the mainstem exceeded 200 mm while 78% of the cutthroat trout in tributaries were less than 200 mm. Tributaries may function as spawning and juvenile rearing areas. Between June 30 and September 21, anglers fished an estimated 6,553 hours on the SFSR above the Secesh River, the East Fork of the South Fork, and Johnson Creek. Sixty-five percent of the effort was expended on the East Fork of the South Fork. Harvest rates ranged from 0.6 to 1.0 fish per hour on four stream reaches. An estimated 5,256 game fish were harvested. Hatchery-reared rainbow trout comprised 53% of the harvest. Although 66% of the anglers used bait, a large proportion (47%) of the total catch was released. 1 INTRODUCTION The SFSR is one of three major Idaho rivers which are being managed for production of indigenous wild steelhead trout. This research program was initiated in 1984 to evaluate the current status of wild steelhead and resident fish in the SFSR and to recommend means of restoring the sport fishery. Historically, the South Fork Salmon River (SFSR) was the single most important summer chinook salmon (Oncorhynchus tshawytscha) spawning stream in the Columbia River drainage (Mallet 1974). Approximately 50% of Idaho's summer chinook salmon redds were counted in the drainage. The SFSR also supported a steelhead trout (Salmo gairdneri) run estimated at 3,000 or more (IDFG 1984). An excellent chinook salmon and steelhead trout (steelhead) sport fishery existed on the SFSR. Nearly 31% of the state's chinook salmon angling and 10 to 15% of the steelhead angling effort occurred on the river. Approximately 4,000 chinook salmon and 810 steelhead were harvested in 1960 and 1963, respectively (Richards 1961, Ortmann 1966). Since the 1940's, man-caused activities (primarily road construction and logging) have caused erosion of unstable soils and damage to aquatic habitat in the SFSR (Megahan et al. 1980, Plans and Martin 1980). Erosion of disturbed soils was initially reported in 1948. By 1965, 15% of the watershed area had been logged. Seventy-eight percent of the logging and 69% of the road construction were on steep, unstable stream-cut lands. Severe damage to aquatic habitat occurred in 1964 and 1965 as pools were completely filled with sediment, spawning areas were buried under sand, and capacities of rearing areas were reduced (Corley 1976). Logging was suspended in the SFSR in 1965 and a rehabilitation program initiated. Although improvements in fish habitat have begun (Megahan et al. 1980), a large quantity of interstitial fine sediment remains, and most of the recovery has yet to occur (Burns 1984). The recommendation of Corley (1976) that "No management activity should be conducted in the South Fork drainage that will adversely affect the aquatic habitat or retard the rehabilitation rate in the river" still applies. As a consequence of the severe habitat degradation, anadromous fish populations in the SFSR declined severely. Chinook salmon and steelhead fishing were closed in 1965 and 1968, respectively. The populations were simultaneously reduced by accelerated hydroelectric development on the Snake and Columbia rivers. It is believed that resident fish populations also declined as a result of the habitat degradation. 2 Initial work began under other funding sources on March 1, 1984. Funding by the Lower Snake River Fish and Wildlife Compensation Plan began September 1, 1984. This document reports results from March 1, 1984 to January 31, 1985. OBJECTIVES To determine the status of native South Fork Salmon River steelhead. To identify the genetic character of South Fork Salmon River steelhead and compare to other Columbia Basin stocks. To determine the distribution, timing, and harvest of South Fork Salmon River anadromous and resident species. To map important spawning areas in the South Fork Salmon River tributaries for anadromous and resident species. To map important rearing areas in the South Fork Salmon River and tributaries for anadromous and resident species. To evaluate contribution to natural reproduction of returning hatchery-reared fish. To provide recommendations for development of a steelhead fishery in the South Fork Salmon River and its major tributaries that consider: a. The role of Lower Snake River Compensation Plan Hatchery supplementation; b. Stock to be used in the event of supplementation with hatchery stocks; and c. Access conditions and quality of fishery. To provide recommendations for development of resident fisheries in the South Fork Salmon River and its major tributaries which would be compatible with anadromous fishery goals. METHODS Adult Steelhead Movements We captured and tagged adult steelhead in the SFSR and main Salmon rivers. We used barbless hooks to capture fish and attached numbered metal tags to their mandibles. All captured fish were anal fin punched, measured (total length), sexed, and checked for marks, tags, or evidence of hatchery rearing. 3 To obtain timing and movement data, we fished areas of the SFSR

    Final Environmental Impact Statement Nez Perce Tribal Hatchery Program Bonneville Power Administration U.S. Department of Energy Bureau of Indian Affairs U.S. Department of the Interior Nez Perce Tribe July 1997 Final Environmental Impact Statement Responsible Agencies: U.S. Department of Energy, Bonneville Power Administration (BPA); U.S. Department of the Interior, Bureau of Indian Affairs (BIA); Nez Perce Tribe (NPT). Title of Proposed Action: Nez Perce Tribal Hatchery Program. States Involved: Idaho. Abstract: Bonneville Power Administration, the Bureau of Indian Affairs, and the Nez Perce Tribe propose a supplementation program to restore chinook salmon to the Clearwater River Subbasin in Idaho. The Clearwater River is a tributary to the Snake River, which empties into the Columbia River. The Final EIS includes a new alternative suggested by commentors to the Draft EIS. In the Proposed Action, the Nez Perce Tribe would build and operate two central incubation and rearing hatcheries and six satellite facilities. Spring and fall chinook salmon would be reared and acclimated to different areas in the Subbasin and released at the hatchery and satellite sites or in other watercourses throughout the Subbasin. The supplementation program differs from other hatchery programs because the fish would be released at different sizes and would return to reproduce naturally in the areas where they are released. The Use of Existing Facilities Alternative proposes using existing production hatcheries and the proposed satellite facilities to meet the need. Facilities at Dworshak National Fish Hatchery, Kooskia National Fish Hatchery, and Hagerman National Fish Hatchery would be used as central incubation and rearing facilities.

  • 2015 Idaho Wolf Monitoring Progress Report
    2015 IDAHO WOLF MONITORING PROGRESS REPORT Photo by IDFG Prepared By: Jason Husseman, Idaho Department of Fish and Game Jennifer Struthers, Idaho Department of Fish and Game Edited By: Jim Hayden, Idaho Department of Fish and Game March 2016 EXECUTIVE SUMMARY At the end of 2015, Idaho’s wolf population remained well-distributed and well above population minimums required under Idaho’s 2002 Wolf Conservation and Management Plan. Wolves range in Idaho from the Canadian border south to the Snake River Plain, and from the Washington and Oregon borders east to the Montana and Wyoming borders. Dispersing wolves are reported in previously unoccupied areas. The year-end population for documented packs, other documented groups not qualifying as packs and lone wolves was estimated at 786 wolves. Biologists documented 108 packs within the state at the end of 2015. In addition, there were 20 documented border packs counted by Montana, Wyoming, and Washington that had established territories overlapping the Idaho state boundary. Additional packs are suspected but not included due to lack of documentation. Mean pack size was 6.4 wolves, nearly identical to the 2014 average of 6.5. Reproduction (production of at least 1 pup) was documented in 69 packs, representing the minimum number of reproductive packs extant in the state. Determination of breeding pair status was made for 53 packs at year’s end. Of these, 33 packs (62%) met breeding pair criteria, and 20 packs did not. No determination of breeding pair status was made for the remaining 55 packs. Mortalities of 358 wolves were documented in Idaho in 2015, and remained essentially unchanged from 2014 (n = 360).
