| Brook Trout - Fair: A variety of insect hatches occurring. Use care not to alarm fish when approaching streams with clear water. |
| Brown Trout - Excellent: Recent rainfall making some streams off color and knocking terrestrial insects in water. This flush of fresh food excites Brown Trout. Fish near or around undercut banks. Try using streamers or spinners on larger waterbodies for some exciting action. |
| All stream stockings announced once a month minimum. Trout streams are in good condition. Long pants or waders protect legs from irritating yellow parsnip and nettles. Gnats and mosquitoes aggressive. |
| Rainbow Trout - Excellent: Weekly stocking continues on most streams. Use spinner baits, hair jigs, or hooks tipped with a small piece of worm, dough ball, or cheese floated through deeper water. Use bait if keeping fish. |
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)
In nearly all cases, Iowa fish are safe to eat. Cleaning and/or preparing the meal causes most of the problems regarding taste or color of fish. Like all living creatures, fish are susceptible to diseases, parasites, and other naturally occurring conditions in the water. If you suspect your fish is affected by any of these conditions, do not eat it. Consider eating smaller and younger fish which usually have lower levels of contaminants than larger ones. Most contaminants accumulate in larger, older fish. For additional information, check out our resources for eating and cooking Iowa caught fish.
