ANGLER ALERT! Due to low oxygen and warm water temps, fish in the Arkansas River from the Pueblo Reservoir dam east to Interstate 25 are under extreme stress.
@COParksWildlife is issuing a VOLUNTARY FISHING CLOSURE on that stretch of river until conditions improve.
We urge anglers to avoid the Arkansas River from Pueblo Reservoir dam to I-25 & fish high country waters. Oxygen levels are dangerously low for fish & water temps are rising. At higher elevations, water temp & dissolved oxygen levels are better.
