Both runs on the Blue are good ducky runs.The upper is a little more exciting with some play waves and one III+/IV- type rapid and simple logistics.There was a recent post about wood.
Clear Creek's only 2\3 run is the Idaho Spgs.town run.The book says 3+ ,maybe in spots at high water,it was a standard beginner run 10-15 years ago.There is a class 2 section between 119 and the put in for Black Rock,might be fun high.Don't miss the takeout.Someone said there are new play waves on this stretch..At low/med flows the three class 4 runs are more 4 -'ish.Dumont would be the most swimmer friendly and least boat abusive,Through town has some 2-3. a few harder drops ,a lot of flat ,and manmade hazzards.Bike scout it.
You might look at the Eagle,Boulder Creek town run,Foxton,So.Platte(Deckers,Waterton, or town run ),or lower NSV.You can tailor a 2-3 run or slightly harder on most/all of those.
