Northern pike. The goal is to reduce the number of northern pike from the middle Yampa River between South Beach and Deerlodge Park and from the upper Yampa River between Steamboat Springs, CO and the Hayden Power Station Intake Boat ramp (originally Project 98c) in order to benefit native fishes and assist in the recovery of endangered fishes. We will coordinate northern pike removal with CPW and FWS. Objectives: In the upper Yampa River between Steamboat Springs and Hayden (Project 98c): • Obtain an estimate of the number of northern pike using a mark-recapture abundance estimator in 2019 and future years as directed. • Remove northern pike on two or more removal passes. • Identify potential spawning locations. In the lower Yampa River sites: • Conduct removal passes for northern pike. • Provide data on pike removed to CPW for analysis. Other species The goal is to reduce the number of other nonnative species from all treatment reaches in order to benefit native fishes and assist in the recovery of endangered fishes. Objectives: • Remove white sucker, white sucker hybrids, common carp, and other nonnative species such as green sunfish, black crappie, black bullhead, and brook stickleback. These species will be removed on all sample occasions if the effort for their removal does not reduce our ability to remove target species of smallmouth bass and northern pike. • Evaluate changes in relative abundance of these species over time using catch per unit effort (CPUE).

Northern pike. The goal is to reduce the number of northern pike from two study sites in the middle Yampa River and one site in the upper Yampa River (appended Project 98c) in order to benefit native fishes and assist in the recovery of endangered fishes. We will coordinate northern pike removal with CPW and FWS. Objectives:
Northern pike. The CDOW is interested in properly managing and effectively controlling the northern pike population in Stagecoach Reservoir and is concerned that the raise will create additional pike spawning habitat; subsequently increasing pike reproduction and potentially increasing pike escapement from the reservoir. The U.S. Fish and Wildlife Service (USFWS) also expressed similar concerns. The UYWCD has agreed to mitigate our concerns by implementing the following mitigation strategies. • The UYWCD will operate the reservoir to manipulate water levels to reduce spring flows over the spillway to reduce potential northern pike escapement. This will also limit northern pike spawning habitat in the reservoir in the spring. • A gravel filter or grate at the wetland/waterfowl mitigation area on the north side of the reservoir will be constructed to prohibit the entry of northern pike and limit access to the spawning/rearing habitat in the wetland/waterfowl area. This will be constructed prior to the reservoir being filled above the current 7,200’ capacity. • Prior to raising the reservoir level, the upland vegetation around the reservoir (between 7200 and 7204 feet) will be cleared up to the new normal high water line to reduce availability of spawning/rearing habitat during the initial years of additional fill. • A barrier will be installed in the existing four foot diameter culvert under RCR 16 to prevent adult northern pike from entering the wetland area upstream of the culvert and further limit available spawning habitat. This barrier will have openings no greater than 1¼ inch and will be installed prior to the reservoir being filled above the current 7,200’ capacity. • XXXXX acknowledges that some level of escapement of northern pike is likely to be occurring from Stagecoach Reservoir. In addition, the UYWCD recognizes the efforts of the CDOW to control northern pike downstream of Stagecoach Reservoir. As part of that control effort, the CDOW is currently implementing a 5-year northern pike control program at Lake Catamount. Efforts of the CDOW could reduce the impact of northern pike on endangered fish downstream. In five years the CDOW will determine the effectiveness of the northern pike control program at Lake Catamount. If it is determined that efforts of CDOW are not effective and significant numbers of northern pike are traveling downstream into critical habitat, including documented escapement out of Stagecoach Reservoir, the UYWCD will develop and implement...
Northern pike. The goal is to reduce the number of northern pike from two study sites in the Yampa River in order to benefit native fishes and assist in the recovery of endangered fishes. Coordinate removal sampling with CPW and USFWS (Primarily accomplished by CPW Project 98a and supplemented by this Project (#125). Objective: Conduct eight removal passes for northern pike from the Little Yampa Canyon and Lily Park study reaches to support Project 98a. Other species The goal is to reduce the number of other nonnative species from two study sites in the Yampa River in order to benefit native fishes and assist in the recovery of endangered fishes.
