If you click on the flows tab at the top of the page, it give you all the relevant flows for the region. At the bottom of the Colorado River Drainage section are the flows for the Blue (through Breck, Silverthorne, and Green Mountain). You'll notice the depressing orange block for the Blue through Breck that has read 5cfs for months now. I'd say the play park is runnable down to 50 but doesn't start getting good 'til over 70. There's a tab for the Tenmile through Frisco, too (but I'm not sure what levels are good there). Unfortunately, the boating seen is typically quite bleak in Summit until May. You'll often find better play in the rivers around Summit than in the actual parks. There is a rumor that the Upper Blue may start running as early as next week

. The Lower Blue through Green Mountain is a bit further but practically runs all the time (beware cold water, class V put-in for a class III run). I think there's a tab for the Vail play park in the Eagle Drainage on the Flows page. I still spend the majority of my time in Summit so let me know if you have any questions or want to go paddle. Just send me a PM or give me a ring.
