We ran Bluegrass yesterday, the flow is definitely good and the water is very warm! Currently Wheatland Reservoir #2 is releasing about 450 CFS. According to the ranch people I talked to, we can expect these flows for a couple of weeks.
Just by coincidence I happen to work with one of the partners at the Flying X Ranch, so we were able to put on at their property which makes this run a reasonable 4 hours or so (about 8 miles). I also got the scoop on why we are not allowed to use their ranch as a put-in anymore. Apparently, they are having insurance problems -- to the point that they are not even allowed to offer their traditional hay ride meals behind horse drawn wagons anymore. So until their insurance problems are resolved, to access their property you have to be a guest of one of the owners there (there are currently 291 owners, many from the Fort Collins area) and those owners have to be on property the whole time your vehicle is on the property. We also had to sign waivers and pay a guest fee of $5 each.
The Flying X people are very nice, and they hope to be able to open up to kayakers in the near future. Through much trouble to themselves, they even took down all of the fences on the creek through the middle of their property, when I mentioned what a pain those fences are to boaters. They did however have to leave up their property line fences, but the lower one was easy to get under (didn't have to go under the upper one).
I don't think their troubles will get resolved this season ("all wagon rides cancelled until further notice"), but I will post when I hear that it is OK for us to use their land as a put-in again.
I think the run would be worth it, even if you had to do the whole long stretch. The water was very warm (rarity for Colorado), there were plenty of opportunities for play, and there was just enough action to keep you on your toes, even outside of the Main Event. From the Flying X Ranch property to the bridge, we only encountered 5 fences and although we made it under all of them in our boats it pays to keep a close eye out for them. (I ended up getting not clearing one, paddle jerked from hands and had to hand roll back up.)
I took a lot of video which I shrunk down for downloading if anybody's interested: http://www.brianbinge.com/pics/kayak.../bluegrass.htm
