avatar Peak Spring Flooding
May 25, 2011 04:14PM
2011 Prediction: Peak flow is expected at or above the 10-foot flood stage in early June at Pohono Bridge.


Selected peak daily and instantaneous spring flood flows recorded at the USGS Pohono Bridge gage (Gage No. 11266500) on the Merced River. Note the difference between 1983's daily and instantaneous peaks.

Largest Flood on Record: Floods can happen due to peak spring melt or due to rain-on-snow events any time of the year. Yosemite's flood of record is 23.45 feet at Pohono Bridge, occurring Jan. 2, 1997, as a rain-on-snow event. Yosemite's records at Pohono Bridge and Happy Isles gage stations date back to 1916.

Was in the valley during the peak last year...our trip this year should be close...

Remembering 1983...backpacked to Litlle Yosemite Valley over Memorial Day weekend. 1/2 of Little Yosemite was under water/snow. The hike on the JMT just before getting to Nevada Falls was a real soaker. (Some of the creeks have been diverted since then.)

Must have been called The Shower Trail instead of Ice Cut.
