Redlands Diversion Dam Fish Ladder - Grand Junction, CO - Fish Ladders on Waymarking.com

"Low-head dams were constructed early in the 20th century to provide irrigation water for farms in Colorado’s Grand Valley. Although important to agriculture, these dams blocked upstream fish movement and eliminated many miles of habitat once suited to the endangered fish. Working with its partners, the CRFP helped restore fish passage on the lower Gunnison River near Grand Junction in 1996 with the completion of a fish ladder around the Redlands Diversion Dam. From 1996 to 2012, some 115,000 native fish have ascended the Redlands Fish Ladder including 122 endangered Colorado pikeminnow, 28 razorback sucker, eight bonytail, and one humpback chub. Fish passage was also provided on the Colorado River upstream of Palisade, Colorado with the completion of fish ladders at the Grand Valley Project Diversion Dam in 2005 and the Price-Stubb Diversion Dam in 2008. Through 2012, 58,000 native fish have passed the more upstream dam, including two razorback sucker, six humpback chub, and 22 bonytail." (from Management tab - (visit link) )

"In 1982 when Redlands was going through a major up-grade of the dam, power canal and generating plant an agreement was reached with the Federal Energy Regulatory Commission and U.S. Fish and Wildlife Service to enter into negotiations should a fish passage be considered at the diversion dam. Studies have been completed by the U.S. Fish and Wildlife Service and the Army Corp of Engineers in this matter. Redlands Water and Power Company worked with both agencies and commented as appropriate during the feasibility study. Construction started on the fish passage in the Winter of 1995 and was completed in the Spring of 1996. The fish passage was built so that the endangered fish species could navigate around Redlands Water and Power Company’s diversion dam to go upstream and spawn in hopes of a full recovery of the native fish in the Gunnison River. The fish that are listed as endangered are: Squawfish, Razorback Sucker, Bonytail Chub and the Humpback Chub.

The Fish Screen was completed and placed in service in 2004. After some initial problems were solved we are able to operate the screen nearly all year until the ice becomes too heavy. The Fish Screen is a V-shaped structure made of stainless steel screens which funnel the fish back out to the river. There is a trash rake at the facility for large objects and the screens themselves prevent some debris from entering the irrigation system. However, the purpose of the facility is to prevent endangered fish from entering the power plant and the pumps. The Fish Screen is operated and maintained by Redlands Water and Power Company employees with complete reimbursement provided by the Endangered Fish Recovery Program. In 2008, we took ownership of the Fish Screen from the Bureau of Reclamation at no cost to Redlands Water and Power Company." (from (visit link) )

Between 17 April and 17 October 2014, 13,331 fish were caught and sorted (9,018 were native and returned to the river; 3,470 were non-native and 843 were hybrids, which were not returned to the river). (from a report by Mr. Travis Francis, Fish Biologist, USFW, Grand Junction, CO)
