Gauge Description:

UC San Diego Scripps Institute maintains a weather station at Devil's Postpile for use in climate research. The gauge shows water height rather than cfs.   Unfortunately there have been problems and the station has not been transmitting data properly.   It may or may not get fixed during 2009.   The station is recording data for later download, so we should be able to get annual data for this station to compare with other gauges and with visual observations. 

Dreamflows.com is now estimating the daily average flow at Miller Crossing based on the flow records linked below. Miller Crossing is below the NF confluence, but above the SF confluence. Miller Crossing Map During most of the year this estimate will be very inaccurate because of the effects of rainfall and lower elevation tributaries. However, at the end of the snowmelt season in June, July or August as flows drop below 1,000 cfs, the estimate should generally be in the ballpark, or within a few hundred cfs. It may not be close enough to decide whether to boat or not, but it should be close enough to go look at the river and then decide whether to boat.

The above estimate is based on records from two gauges. There was a gauge from 1921 to 1991 at Miller Crossing, and there is now a daily calculation of Millerton Full Natural Inflow. Comparing these two measurements during the years that have records for both, it appears that during the summer when flows at Miller's Crossing drop into a boatable range, those flows tend to be around 3/10 to 4/10 of the calculated flow at Millerton. The dreamflows calculation is a bit more precise.
