Show waters associated with any selected trout species.

These are river-level reports, not confirmation on each mapped mile.

Map layers

Reviewed access points load from the approved Michigan V1.0 access release. Basemap features are context, not additional verified coverage.

Sources & scope

River geometry

Michigan launch geometry uses Michigan DNR FishHydro source geometry and, where required, approved USGS 3D Hydrography Program connector geometry to bridge verified mainstem gaps. Mapped-mile values are stored resolved geometry measurements, not surveyed legal boundaries or statements of public access.

Access and species

Approved Michigan DNR boating-access records are displayed as reviewed map points for the selected water. Access records can change; current agency information and posted notices control on the ground. Source identifiers and review dates are retained in the approved Eddy Atlas access release. Species reports apply to the river, not every mapped mile.

Current coverage

Published Michigan launch waters are discoverable directly on the map; the sidebar updates to the waters visible in the current map area. Satellite, Terrain and Roads are display choices only; they do not change Trout Eddy review status. The My Location control uses browser permission for a one-time map center and is not stored by Eddy Atlas. No statewide ownership layer or live USGS conditions are included.

Before fishing

Check current agency information, posted notices and reach-specific fishing rules. A line or marker does not establish fishing permission.

Eddy Atlas: Interactive Trout Fishing Map & Water Explorer

Eddy Atlas is Trout Eddy's interactive way to discover trout water and connect the map to the fishing information behind it. Explore mapped waters, reviewed access information and Trout Eddy fishing guides without turning the map into a second library of duplicate river pages.

Find the Water

Use Eddy Atlas to move from geography to an actual fishery. Select a supported water to see the mapped reach and available reviewed access information, then continue into the full Trout Eddy Water guide when you need the deeper fishing details.

Go From Map to Fishing Guide

Eddy Atlas is built for discovery. Trout Eddy Water pages remain the detailed fishing resources for individual rivers, streams and lakes, including fishery character, trout species, techniques, hatches, seasonal information, access context, regulations and related gear.

Current Eddy Atlas Coverage

Eddy Atlas is currently in its V0.1 proof stage. The live proof includes one mapped reach of Michigan's Au Sable River, from Burton's Landing toward Wakeley Bridge, together with one reviewed access record. Other waters shown in the interface are not yet part of the live proof.

Coverage Grows With Verification

Trout Eddy does not treat every blue line on a map as trout water or every nearby road as legal access. New Eddy Atlas records are added only as the geographic data, supporting sources, access evidence and publication checks required for that release are completed.

A Map Is the Starting Point, Not the Whole Fishing Guide

Eddy Atlas helps answer the first question: where should I look? From there, use Trout Eddy's individual Water pages to understand the fishery itself. A mapped reach does not by itself establish trout status, fishing permission, public ownership or current regulations. Always use the supporting information and official sources provided for the water you plan to fish.
