Below Antero fishing report
Updated November 7, 2026.
The release below Antero is only about 8 cfs. With the reservoir refilling after this spring's drawdown, expect very low, cold water and slow fishing on tiny midges in the middle of the day.
Until Antero refills, the Dream Stream and Eleven Mile Canyon are better choices nearby.
