There is a stick gauge a quarter mile upstream of the takeout. The gauging station is clearly visible 150 feet below the trail. An optimium level to run the most rapids might be XXX on this stick gauge. On the 15 June 2008 the water was high, on the 23 June 2008 and 3 June 2007 the water level was close to ideal. Comparable gauges might be SF Merced In Wawona and SF Kings.
