Stream Segment Length: 0.20

Amenities

Amenities at Dunning Spring include:
  • Picnic Area
  • Trails
  • Good/Excellent Shorefishing

Brook Trout - Slow: Brook trout more interested in spawning than feeding making catching more difficult. Dabbling a fly through narrow vegetated runs or find a deeper pool above a beaver dam may grab a brooks attention.
Brown Trout - Good: Avoid walking in cleared gravel areas in faster moving water. These are trout nests or redds. Try using flies or crankbaits imitating minnows or other small trout.
Rainbow Trout - Good: With the end of catchable trout stocking, plenty of fish remain in the stream to confound anglers. A small chunk of worm or cheese under a bobber fished through a deeper hole may turn a rainbow head. Cut line on deeply hooked fish if returning to water.
As of November 1, trout stream stocking is finished for the year. Staff would like to thank all our trout anglers and supporters for making this season fun and rewarding. Fall community pond stocking in full swing. Visit our website to find out more. Many trout streams flow through public areas where hunting occurs.

Since 2019, this very small stream began receiving an annual stocking of domestic Rainbow Trout fingerlings. Prior to this, it received Brook Trout fingerling stockings. This stream is in a beautiful Decorah city park with a continuous flowing waterfall.(2022)

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. 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.
