Colorado Parks and Wildlife Commission approves Northern Water's Fish and Wildlife Mitigation and Enhancement Plan on Poudre River
STEAMBOAT SPRINGS, Colo. - The Colorado Parks and Wildlife Commission has unanimously approved the Fish and Wildlife Mitigation and Enhancement Plan submitted by Northern Water for the Northern Integrated Supply Project on the Poudre River in Northeast Colorado. This plan is designed to address the impacts to fish and wildlife due to the development and water diversion associated with NISP.
Colorado Parks & Wildlife (CPW) staff has been talking with Northern Water about the concept of this project for the last decade. Northern Water, CPW and the Department of Natural Resources have been discussing the Fish and Wildlife Mitigation and Enhancement Plan project in earnest since October 2015. Following more than two years of discussions, Northern Water presented and released a public draft of the Plan at the June Commission meeting.
CPW staff feel that Northern Water's plan provides a reasonable solution for fish and wildlife mitigation.
“We understand the public’s concern for the river which is why CPW staff has been engaged in discussions for close to a decade,” said Ken Kehmeier, senior aquatic biologist with CPW. “If we were not involved from the onset, the level of mitigation, enhancement and protection of the river corridor and aquatic habitat would not be such a large part of Northern’s plans,” said Kehmeier.
Northern Water has made modifications to its project design and operations, and has committed to work with CPW. Recommendations by CPW are aimed at minimizing impacts to fish and wildlife habitat during all phases of the project. Some of these include:
Peak Flow Operations Plan, pg. 46
the "conveyance refinement" flow, or year-round baseline flow plan for the river
the retrofit of four diversions that currently do not allow fish passage or sediment transport
Big game habitat mitigation and enhancements
The Peak Flow Operations Plan will minimize the impacts of NISP operations on peak flows, higher flows in the spring. Peak flow is important for maintaining spawning habitat for fish and aquatic life. Northern Water has agreed to ramping water diversions gradually to avoid sudden changes in river flows and allow fish to adjust.
The conveyance refinement is crucial for aquatic habitat and river connectivity. This process is intended to eliminate existing dry-up points on a 12-mile stretch of the Poudre River through Fort Collins. Average winter flows at the Lincoln Street Gate will be nearly doubled compared with current levels.
“The conveyance flow program is significant to the fishery and aquatic life because it keeps water in the river on a year round basis,” Kehmeier said. The conveyance flow will also meet the Fort Collins River Health Assessment Framework flow of 20 cfs 97 of the time at the Lincoln Street Gage.
"Overall, the conveyance flow will significantly benefit the aquatic life in the river during the low flow times of the year," Kehmeier said.
As part Northern Water's plan, a new reservoir will be created for water storage and recreation opportunities for the public. Northern Water has agreed to provide $3 million plus an additional $50,000 per year for CPW hatchery expansion so that the new Glade Reservoir can be managed as a recreational fishery. Additional fishing opportunities will benefit the local and Colorado economy, as the fishing industry generates $1.9 billion in economic activity annually.
Northern Water has also agreed to provide wildlife habitat mitigation and enhancements on the west side of the reservoir, including the purchase of 1,380 acres to protect the reservoir drainage area and big-game habitat from development. This is critical winter range habitat for a non-migratory elk herd.
CPW recognizes that the water quality mitigation is not complete and the proposed project still needs to go through a 401 certification as part of the federal Clean Water Act process. This certification will be conducted by Colorado Department of Health and Environment. As part of a recommendation prompted by the Colorado Water Plan, CPW staff will participate in that process and feel that it will further enhance protection of the Poudre River.
Temperature issues occur in the river on a year-round basis the conveyance refinement and multi-level outlet tower at Glade Reservoir will aid in mitigating the temperature issues and other potential water quality issues, for example, sediment transport during low flow. The releases from the reservoir will be aerated and the multi-level outlet will allow water to be mixed if it is needed at a particular temperature.
The Poudre River Adaptive Management Plan, pg 97, will allow a collective group of interested parties that include the City of Fort Collins, Northern Water, CPW, Larimer County and others to go back and make corrections to the plan and operation if any are necessary. The plan will also allow CPW and other parties to continue conducting projects to benefit the river to include floodplain connection, fish habitat enhancements and mitigate sediment transport.
The Fish and Wildlife Mitigation and Enhancement Plan will now go to the Colorado Water Conservation Board for review.
