David, its hard to plan on Bailey this time of year, as it is completely dependent on tunnel flows. It could be running, but you typically don't know until a day or two before if the flows will hold. I will update with Denver Water plans as I get them.
Its a good idea to go with someone who knows the run your first time, and there won't be a shortage of those folks this season. Bailey is likely to be the savior of the season for many front range boaters. I haven't been getting out on Saturday, but if Bailey is running, there will be boaters.
P.S. 255 cfs was fine.
