Henry's Fork

Flow is about 812 cfs below Ashton Dam, and 1190 cfs at the USGS St. Anthony gage.   With low flow Midge activity dominates dry fly fishing during wind free periods. A few early season BWOs emerging downstream of Ashton Dam. Best chances to see this will be during overcast, wind-free days.  Rainbow trout spawning on the lower river will begin soon. Avoid spawning areas.
