Dunning Spring

General Information

County: Winneshiek
Location: Located in Dunnings Spring Park on the north side of Decorah off Ice Cave Road.
Stream Segment Length: 0.20

Amenities

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

Water levels on most are low but fishable. Trout stream stocking continues on all steams as scheduled even though some are not announced.
Brook Trout - Fair: The best brook trout streams are heavily vegetated making fishing difficult. Dabbling a fly through the narrow unvegetated runs is best or find deeper pools above beaver dams.
Brown Trout - Good: Brown trout are hard to catch in clear water. Anglers may have to be more stealthy when approaching streams. A variety of terrestrial insect patterns will work especially crickets, ants, and grasshoppers.
Rainbow Trout - Good: A small chunk of worm or cheese under a bobber fished through a deeper hole will turn a rainbow head. Cut line on deeply hooked fish if returning to water.

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. Here is a list of current fish consumption advisories for Iowa lakes and rivers.
