This color coded stream map lets you search any river, lake, or stream by state and county. Check nearby flow gauge data. Navigate right to the water's edge.

Touch "Go" for instant driving directions. Travel along the stream with GPS tracking on topographic maps. Mark your favorite spots for your next trip.

Stream Map USA is a complete GPS mapping and navigation tool featuring the most comprehensive searchable stream map ever made. Designed specifically for anyone spending time on the nation's waterways, this edition maps all waters in the states of Arizona, Colorado, Idaho, Montana, New Mexico, Nevada, Utah, and Wyoming.

Stream Map USA features a searchable color coded map of America's rivers, lakes and streams that can be viewed on roadmaps, satellite images or topographic maps. As you travel, the map displays your location and tracks your progress even when there is no service. Both roadmaps and topographic maps can be stored on the phone for offline use.

Custom waypoints provide navigation and allow you to plan your trip. Add a waypoint where you'll access the water, then tap "GO" for turn-by-turn driving directions right to that spot. Add additional waypoints for campsites, fishing holes, trailheads, equipment caches, pickup points and more. Now "Target" your next waypoint and the built-in compass points the direction and counts down the distance right to that destination.

When planning a trip on the water, it is always wise to know the water conditions in advance. As an added feature, Stream Map USA includes the ability to access real time stream gage and flow data for many streams and rivers.

No matter what activity you enjoy on the water, we're confident you'll find Stream Map USA a helpful addition.

Stream map USAA Mountain West region

This is a terrific app! I read about it in a fly fishing magazine. I have so far only used it on the Colorado River at Lees Ferry but it is extremely helpful. The detail on the Maps is excellent and allows you to even waypoint a specific rock or point as a way of delineating a very fishable channel or prime location.
Also very helpful is the ability to download detailed maps at home so that they are available on stream where there may be no Wi-Fi or cell service available.
On smaller streams in more remote locations I suspect it would be highly useful in bushwhacking across hairpin turns in the stream and even for finding your way back to your parking area.
In summary, this is simply a five star product I would no longer wish to be on stream without.

Good stuff

As a Google Maps blue line junkie, this app is right up my alley, and a clear upgrade from my days of zooming in Google to look for river names and locations. I especially love the topo view. The different colored lines make it quick and easy to tell tributaries apart from main river stems. Just make sure to download the correct region. Hopefully we will see an in-app map expansion option down the line.
