District-Wide Trout Stream Fishing Report

Brook Trout - Good: For stained water, try using a streamer or minnow imitation.
Brown Trout - Good: A nice variety of insects have been hatching in the evenings. Try using a #18 blue wing olive or #14 or #16 caddis fly imitation. Strong midges hatches have also been occurring.
Rainbow Trout - Good: Remember, a few of our streams are not stocked in July and August as these streams tend to get too warm for cold water fish. Please refer to our calendar and map to find out which ones. Spin fishers might try using spinners or worms for success.
Trout streams with better watersheds are fishable but flows are up. Trout anglers be aware! Wild Parsnip is still blooming. Take care when walking through this weed when getting to your favorite stream. Don't let it touch your skin. It reacts with the sun and causes horrible blisters.

Fishing Summary

This very small stream receives an annual stocking of domestic brook trout. This stream is in a beautiful Decorah city park with a continuous flowing waterfall. Sampling data indicates 180 brook trout per mile with fish up to 11 inches collected. This is not an estimated population and actual trout numbers will be higher. (2012)

Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information.
