KMZs and other files showing the distribution of wild trout in UT are available from the download system.

Across the state of Utah, whenever the elevation climbs above about 5,500 feet, there's a good chance there's wild trout.

We have just begun coverage of the western US.  Already, UT is receiving substantial coverage.

In the image above, turquoise lines mark stream segments designated as cold water habitat by the UT DEQ.   It, roughly speaking, defines the areas where it is possible to locate wild trout.  Cold water habitat within Indian Reservations is NOT coded in this file, so a subtantial amount of trout habitat is missing here.

While hard to see at this scale, underlying the turquoise streams is specific information about the Bonneville Cutthroat Trout, the only "native" species with widespread habitat in the state.  South of I70/US50, near the Colorado border, you can also see a green squiggle which corresponds to the population of Greenback Cutts discovered there a couple of years ago.

Keep in mind that cold water habitat which doesn't hold natives is likely to hold "exotics" like brook, rainbow, and brown trout. 

All of these datasets are currently available for download.  Check out the "Natives" page of the downloads tab, and the Utah category in the "Streams" section of the "download" page.  We'll be adding more content to Utah as we find the time.
