Historical flow data is available for this reach at USGS  11316700 .

Inflows from the middle fork and south fork also effect flows in this reach.  

EBMUD operates flow gages on the Middle and South Forks of the
Mokelumne River (USGS 11317000 and 11318500). Data from these gages could
help estimate the total flow in the Ponderosa Way run, if they were available in real time.
