This is a bizarre post-season run courtesy of the ranchers of south-east Wyoming. The water in Wheatland Reservoir #2, which comes from the Laramie River, is siphoned off into Bluegrass Creek. You will have a 17 run with 20+ fences over the creek, 4 V to V+ rapids, 2 or 3 miles of fun III/IV, and 13+ miles of swift moving Class II.
The put-in is truly bizarre with the water coming out of a hole in the side of the hill and transforming an otherwise sagebrush filled desert draw into a class V paddler's oasis . The stream-bed is only as old as the diversion, which was completed in 1886 by Chinese immigrant labor (history lesson available here:

Those without time to complete the entire run to highway 34, or simply wanting to milk as much whitewater out of their day as possible will enjoy lapping this section via a faint trail on river right. I also recommend using this trail to scout the entire top section, there are very few eddies and even fewer places where it is easy to get out in this first section of action.
The unnatural nature of this run is intimidating, and although it does tend to paddle more cleanly and easily than immediate appearances would indicate, you will immediately notice while scouting that this is no place to swim and a scary place to find yourself upside down. Despite it's bizarre nature, the top 2/3 of a mile is exceptionally high quality with 3 waterfalls of varying height and technicality. A splashy and hole strewn run out below the waterfalls careens around several blind corners before unceremoniously dumping paddlers into the main channel of Bluegrass Creek. Don't forget to scout this last section, a midstream boulder hidden in the blind corners claims more carnage than any of the spectacular waterfalls elsewhere on the run.
After merging into this large (dry) drainage paddlers can relax somewhat, there is about 10 miles of Class II until the next significant rapids; however, prepare to do the back-ferry to barbed-wire limbo maneuver 20+ times negotiating fences until you reach the take out. The fences are sketchy, straight up, and paddlers have definitely hit them, gotten stuck, torn clothes etc. Stay heads up, keep spacing, communicate well and the run can usually be done with no fence portages. But this is certainly subject to change.
The action eases back on with 3-4 miles of class III- IV mini gorges and beautiful prairie scenery. Granite rock formations and frequent wildlife sightings abound.
Just when paddlers begin to think the class III is about to fade back to flatwater, the creek descends into an obvious gorge. The Main Event is a spectacular mulit-part rapid that looks like something straight out of California. A series of slides build in size and intensity through several holes before launching off the powerfully folding lip of the Main Event. The ambitious should gun for a monster boof here, but realize that the vast majority (>99%) of lines will look much more like the flushing of a toilet. A hectic boiling cauldron leads to a final slide with a powerful hole with a nice curler boof on river right.
Below the main event a quick moving 3 mile sprint (with numerous fences) will deliver paddlers to the highway 34 bridge and their take out.
