Brook Trout - Fair: Brook trout taking a variety of flies imitating gnats, midges, caddis or an occasional mayfly. Use care not to alarm it when approaching the stream in gin clear water.
Streams maintain nice holdover numbers for the casual angler. With the start of turkey season, anglers should avoid wearing red, white, or blue. The calendar is now available on-line at https://www.iowadnr.gov/Fishing/Trout-Fishing.
Brown Trout - Good: Best time to fish spooky brown's is when water is off color. Use lures that mimic small minnows or midges.
Rainbow Trout - Good: Find rainbows in head ends of pools. Fish the afternoon hatches for fun action.

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)
