There are lots o' good creeky runs in the typically short Utah Spring runoff. The last couple years runoff has been excellent due to the gratuitous snow fall. The previously mentioned runs are good (I think I have done them all except one), but there were a few omissions
When water is high the Ogden and Logan Canyon runs are sweet. The Upper Provo (as previously mentioned) has sic creeky sections and a runnable triple waterfall (30 40 feet each drop), but the last drop is sketchy.
Big Cottonwood Canyon (creek) is sictor when pumping, but is very stout and needs to be scouted foot by foot for wood. Little Cottonwood is death on a stick (wood). Another gnar but hairy creek, runnable in sections (including some waterfalls), is Bells Creek, but there are some 'hit the eddy or die' moments.
The Price is pretty good, nice and continuous 3-4 shit. Cottonwood Creek is a nice class 3ish run. Ferron creek is fun but woody. Salina creek is good but usually boney. The Box of the San Rafael is fun as shit.
Or just run the Grand Canyon.
More a less a Utard myself, I agree with the earlier comment... It seems like there would be more good boating along the Wasatch Front. There is good water but the season is uber-short, or sometimes non-existent.
Later fuckers. I got to go to church.
