From the Great Falls Tribune:

_Montana Fish, Wildlife & Parks on Wednesday closed the Big Hole and Jefferson rivers in their entireties, effective 12:01 a.m. Friday, because of low flows that threaten trout and grayling.

“Flows on these rivers have reached critical levels, which warrant full closures per the drought plans developed by the respective Big Hole and Jefferson community watershed committees,” said Bruce Rich, FWP regional fisheries manager in Bozeman._
