Fishing was closed on the entire Big Hole and Jefferson Rivers due to low stream flows. The closure began at midnight on Aug. 23. The Jefferson River drought plan recommends a river-wide angling closure when stream flows fall below 280 cubic feet per second (cfs) at Twin Bridges. On the Big Hole, the drought plan triggers a river-wide angling closure when flows fall below certain thresholds. Streamflows fell below 100 cfs at Wise River and 150 cfs at Melrose, prompting the closure.
Precipitation was not in the forecast.
