Elkhead Reservoir Fishing Classic Tournament targets smallmouth bass and northern pike

Upper Colorado River Endangered Fish Recovery Program

From WesternSlopeNow.com (Rebecca Hykin):

The four native fish involved with the program are the Colorado Pikeminnow, Bonytail, Humpback Chub, and Razorback Sucker. As these unique fish are found only in this part of the world, the Colorado River Basin, the decline is due to the loss in habitat and several non-native fish species preying on them, including Small Mouth Bass, Northern Pike, and Walleye.

“The fish that we’re trying to remove compete for resources with the native fish as well as they are predatorial fish and they’ll eat the native fish as well,” said Tory Eyre, Aquatic Biologist with Colorado Parks and Wildlife (CPW).

These non-native fish are coming into these native fish habitats from reservoirs overflowing and from a way that is a bit more unorthodox.

“People are moving live fish from one body of water to another and that is illegal on the West Slope of Colorado, and when we have folks that are doing that, it results in a lot of our time and dollars to try to eradicate those species from areas in places that we don’t want them to be,” said Lori Martin, Senior Aquatic Biologist with CPW.

Eyre explained the various instinctive recover efforts helping to save these native fish, “we propagate fish so we raise fish in hatcheries and stock them. We alter habitat [and] try to alter flows. Then our involvement is with the non-native removal.”

Eyre added, “We placed gill nets in the backwaters that are a certain mesh size that targets the Northern Pike and we try to catch them in while they are entering the backwater to spawn.”

CPW has also worked with other program partners to install spillway screens in reservoirs at Elkhead and Highline Lake State Parks to prevent non-native fish from escaping into the Yampa and Colorado Rivers.

“It allows us to stock warm water fish that are okay with the recovery program into Highline Lake and the purpose of it is to keep those fish in the lake and not allow them to get in the Colorado River,” said Alan Martinez, Park Manager for Highline Lake State Park.

However, those with the initiative have been running into a small issue as the recovery program is controversial for some people. Eyre explained, “Small Mouth Bass and Northern Pike are sport fish…people like to catch them.”

As this is upsetting to some anglers, CPW has been working with the program’s agencies, and with anglers, to address their frustrations.

“We’re trying to provide opportunities for anglers for similar species in waters or areas where there is no interaction with native fish,” said Martin.

To encourage involvement by the angling public, CPW is sponsoring the Elkhead Reservoir Fishing Classic Tournament from June 24-July 2 in Craig.

“The aim is to have anglers help us remove small mouth bass and northern pike so we that can better provide a compatible sport fishery that’s in line with endangered fish recovery efforts downstream,” said Martin.

With all of the efforts in helping to reduce the non-native fish to increase the native fish populations, CPW officials say some improvements with some species have already been made in some locations along the Western Slope.

“This is kind of our one chance to recovery these species. They’re not found anywhere else, so if they’re gone, then they’re gone, and they’re gone forever,” said Eyre.
