Welcome Back to the NTC’s The Voice of the Driftless. By Jeffrey S. Broberg
Well it looks like the weather is not cooperating for the end of the Catch and Keep Trout Season in SE Minnesota. Earlier in the week rain covered much of the Driftless but left the center of Winona County and Fillmore counties have a Flash Flood Watch for the entire region.
You might find suitable fishing in the headwater streams. The trout are putting on the feed in their pre-spawn stage and fishing reports are showing abundant caddis and strong bites on nymphs, woolly buggers and terrestrials as well as large streamers. This is the time of year it is fun to try mouse patterns for big fish. The spin fishermen will have an advantage if the water turns cloudy and florescent colors will be the key
Brown and Brook Trout are preparing to spawn.
The pre-spawn stage from mid-September to November will cause the adult trout to develop their intense fall breeding colors and to start looking for mates and suitable sites for their redds. This usually means that they come out of the big rivers and deep waters in search of gravel beds.
MNDNR has some great pictures of fall trout here:
Here is a great 8 minute YouTube video of Brook Trout building their redds in a little Stream in Virginia
As the spawning season unfolds it is important that anglers not disturb the redds or muddy up the streams. The trout bury their eggs in the gravel and the eggs will be crushed and killed by wading across the redds. Conserve out trout and be careful to avoid wading through the spawning grounds
