Cooler weather this week will definitely help the fishing here on the lower Clark Fork river. Dry fly fishing has been pretty good all summer and at this point for the most part it’s all about hoppers and droppers. Mornings have been best when the day is still cool and the sun still low. Above St. Regis be sure to cover water and keep the boat moving. Look for fish in faster current, along fast banks, and especially in riffles and runs that are moving along.
Keep in mind this time of year is all about fast water down here on the lower Clark Fork river. Think oxygen and look for fish in riffles and rapids for the most part.
As much as August is about hoppers, don’t get married to a big bug all day. Afternoons and especially evenings it seems there’s often been better activity on small, more realistic bugs like caddis, pmds, parachutes, that sort of thing. A great cover all bug to that end is a size 12 tan parachute hopper.
Nymphing will definitely produce some bigger fish from the depths of the rapids if that’s what you’re looking for as fish are concentrated in those areas this time of year.
There are currently no restrictions on the lower Clark Fork and we haven’t had any restrictions yet either. It’s actually been a fairly average summer and to date we’ve only had a few really hot days.
Expect a nice week of weather with partly sunny skies and average daytime temps in the 70’s and low 80’s. There is a chance of t-storms through midweek but generally speaking we should have nice, stable run of days and pretty darn good conditions here on the lower Clark Fork River.
