Area streams in good condition. All stocked streams are announced at least once a month. Stocking continues at traditional rates, weekly or bimonthly. The only activity on private property open to fishing is angling.
Brook Trout - Fair: Good hatches of a variety of gnats, mayflies, caddis flies, and midges occurring.
Brown Trout - Good: Fish near or around logs or undercut banks. Spinner baits work well. Also try using streamers on larger waterbodies for some exciting action.
Rainbow Trout - Excellent: Use spinner baits, hair jigs, or hooks tipped with a small piece of worm, bread, or cheese floating through deeper holes. Freshly stocked fish are waiting to take your bait.

Twin Springs is stocked weekly April through October with catchable 10-12 inch Rainbow Trout. This fishery contains a naturally reproducing population of Brown Trout. Sample data from 2011 showed 400 Brown Trout per mile with fish up to 11 inches collected. This is an estimated population and actual trout numbers will be higher. South Pine strain Brook Trout were stocked from 2000 through 2004 with only spotty natural reproduction. Twin Springs runs through a beautiful city park with lots of tree cover. Bank access is easy. There are both electric and non-electric campsites. A playground and restrooms are available to anglers in the campground. There are also hiking trails and a multiuse trail located within or near the park and the Upper Iowa River is close.(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.
