Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.
On the Wild Trout Streams Open to Public Fishing list (Iowa Department of Natural Resources, read 2026-10-24). All waters with this designation
Listings marked Unclaimed are built from open map records and the business's own website: confirm licensing, rates, dates and hours directly.

None of our destination hubs is within 40 miles in a straight line. The trip planner builds a trip around the water itself: the guides and shops listed within 40 miles of it, its gauges and its nearest towns and airports.
No hub within 40 miles
Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.
At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.

Not a statement of access, fish presence or conditions.
A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.
Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: the Wild Trout Streams Open to Public Fishing published by Iowa Department of Natural Resources. Water type is our own classification.
