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.

Stream Map USA is a complete GPS mapping and navigation tool for anyone spending time on the nation's waterways. This edition covers the states of California, Oregon and Washington.

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.

App Not Supported

App Support link goes to page that no longer exists. I did my recent os update and now the app is crashing constantly. It will not even let me save any changes on my waypoints/flags. Needs an update, SERIOUSLY. And when you do update this, please fix the names of the creeks/rivers...I cannot read them at all. They are so microscopic it’s impossible. When you zoom in to read them, THEY GET SMALLER. You have to zoom all the way in to read anything, then back out to see where the heck you are, so it’s ridiculously UN-user friendly. I am surprised at how much you are charging for an app that is not supported. ??? If it was, and it stopped crashing constantly and you could actually read the creek names, I would give it a 5 star rating, so please do that and I’ll change my review. The idea is FANTASTIC and it has been extremely helpful on our rockhounding trips in the past.

New version works

I was reluctant to buy because of the negative reviews, but the revised version seems to have fixed the bugs. The app is working well on my iPad and shows countless little streams throughout my area. It did miss a little stream class to my house, but every other stream shows on the map. I’m happy.

I’d like a refund...

This app is hard to use, does not provide the information I was looking for, and does share much info on MAJOR waterways in my area. I would really like a refund.

This could be such a cool and useful app but it needs more beta.
