Fish Adapt to Menu Changes in Colorado's Gore Creek

While midges and worms, which are less vulnerable to environmental stress, are increasing in a popular Vail creek that runs parallel to I70, those bugs that prove a water is “pristine” — mayflies, stoneflies and caddisflies — are disappearing, says Sarah Mausolf in the Vail Daily. “Given Gore Creek’s reputation as a trout mecca, researchers were surprised to find the bugs are actually healthier in the nearby Eagle River. The water district discovered the bug problem while studying the effects of treated wastewater on the Eagle River.”
