Brook Trout - Fair: Fish the weed lines and head end of riffles for actively feeding fish. Terrestrial insects abundant.
Brown Trout - Good: Dirty water favors Brown Trout anglers. Increasing terrestrial insect numbers such as crickets, beetles, grasshoppers washing into streams creates a feeding frenzy for brownies.
Rainbow Trout - Good: A few streams get too warm for stocking Rainbow Trout during the heat of the summer, specifically July and August. This is an annual occurrence. Not to worry. Plenty of fish remain in the streams. Stocking the other streams continues as scheduled.
Trout streams continue to be stocked every week even if not announced. Most area trout stream current remain elevated. Clarity much improved. Use care when crossing or fishing in faster current.

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)

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.
