The Big Gypsum Valley is 34 miles east of Dove Creek, CO along Colorado Route 141. It is a BLM area that is north of Disappointment Valley and south of the Paradox Valley.
There wasn’t any activity here during my visit but the flow appears to be unusually low. I checked the web site info for flow at Bedrock for the time that I hiked and it was 200 cfs. This is too low for rafting and well below the median value of 1070 cfs for the day I visited. The discharge from the McPhee Reservoir has been 75 cfs for the previous week, after spending some time at 500 cfs. The historic average discharge for this time of year is about 1400 cfs.
