Acidic water cited in fish kill

Jim White, an aquatic biologist with the Colorado Division of Wildlife, tested the water in Mud Creek on Oct. 14, 2009.
Water quality in Mud Creek was disastrous the day he tested, White said. The level of dissolved oxygen, 3 or 4 parts per million, was below the 5 ppm considered rock-bottom to sustain fish, he said. White said he took pH readings – a measure of acidity – of 3.9.
“Stomach acid measures 3.4,” White said. Neutral water has a pH of 7, and alkaline water is above 7.
The creek was home to a confirmed pair of native species of fish, the bluehead and flannel-mouthed suckers.
