Assessment of the Fishery Improvement Opportunities on the Pend Oreille River: Recommendations for Fisheries Enhancement: Final Report.

Kalispel Resident Fish Project: Kalispel Tribal Hatchery Operations and Maintenance, 1999 Annual Report.

“…Some of these factors included water elevation fluctuations; lack of overwinter cover for age 0+ bass; and inadequate recruitment of largemouth bass into the system. The University of Idaho also performed a study during this time (Bennett, Liter, 1991) and concurred with the above factors and proposed similar recommendations of the assessment study published by Ashe. Ashe, et al (1991) indicated that growth rates of largemouth bass during the first four years in the Box Canyon Reservoir were lower than bass from other locations of the northern United States, and conversely, growth rates after the fourth year were comparable or even higher than other locations.…”

Temporary Restoration of Bull Trout Passage at Albeni Falls Dam

“…The USFWS required all sampling efforts for bull trout be suspended once river temperatures reach critical levels. A study by Ashe and Scholz (1992) of the whole Box Canyon Reservoir between 1998 and 1990 only produced four bull trout during 216.6 hours of electrofishing effort for a calculated CPUE of 0.02 fish per hour. During 2003 study by Geist et al (2004) a surprising number of bull trout were caught in a short period of time producing a CPUE of 0.69 fish per hour.…”

“…As a result, the fragmented bull trout populations in Box Canyon went into "decline" and are in imminent danger of extinction unless immediate action is taken to restore the migration corridor. In the Pend Oreille Basin of Washington and Idaho, there is a paucity of bull trout in tributaries located below Albeni Falls Dam (Ashe and Scholz 1992;Scholz et al 2005aScholz et al , 2005b Above the dam bull trout are more abundant in the Priest River drainage (Fredericks et al 2002;Dupont and Horner 2004), several inlet tributaries of Lake Pend Oreille, notably Trestle, Granite and Gold creeks (Fredericks et al 2002;Downs et. al.…”

“…Juvenile ovenvintering suryi\.al has been determined to be the limiting factor for largemouth bass (.\I;icr-optwrrs sdmoiti~s) in the Box Canyon Resemoir ( Ashe et al 1991. Bennett 1991.…”

“…estimates are approximately 6 pounds per surface acre in the Box Camon Reser\.oir. Ashe (1991) and Bennett (1991) suggested the possibilit!-of an off-site rearing facility to supplement the number of jusenile largemouth bass lsithin the Box Canyon Resen.oir.…”
