Colorado Parks and Wildlife is set to begin the next phase in the continued efforts to eradicate zebra mussels at Highline Lake ( [log in for link]
) and stop the spread into additional waters.
During this phase, CPW will apply EarthTec QZ, an EPA-registered copper-based molluscicide, to the lake. This is the same copper-based molluscicide applied to the lake earlier this year.
Due to the potential for accumulation of copper in the edible portions of fish, effective Fri. Nov. 3, CPW will end the emergency salvage regulation that went into effect on October 9.
Under the authority of Wildlife Commission Regulation #104 F.1, effective Friday, Nov. 3, Highline Lake will close to fishing until further notice.
The emergency fishing closure was approved by CPW Director Jeff Davis on Tuesday, Oct. 31. This action only pertains to Highline Lake. All existing regulations on Mack Mesa, Mack Wash, and surrounding bodies of water remain in effect.
CPW is also advising waterfowl hunters planning to hunt using blinds at Highline Lake to leave dogs at home. Dogs should not enter or drink the water until further notice, if you choose to bring your dogs.
