Gauge Description:

Currently there are no data comparing boat to the discharge values measured at the USGS gage 08378500 located on the Pecos River near Pecos NM.


Long term data (1919-2007) are available for discharge measured at USGS Gage 08378500. The monthly mean discharge for May and June are 330 and 244 cfs, respectively. These monthly means would indicate that boating should be possible in May and June of each year.


NRCS Snotel operates a station at Wesner Springs. This station has been operating from 1990. Statistical analyses of the data from the Wesner Spring station indicates the following: Snow water equivalent measued on April 1 is a good predictor of the monthly mean flow of the Pecos measured at the 08378500 gage. Snow amounts near the long term mean on April 1 predict that the monthly mean flow in May will be near the long term average flow. Snow levels  at the Wesner Springs Station can be accessed via


What all this means is one can use the snow accumulation amounts at Wesner Spring in April to determine if a boating trip on the upper Pecos will be feasible in May. If you want further details on these analyses contact me at
