The flood project responds to releases from the upstream reservoirs, so obtaining their operation during flood events is important to the flood project operation.  Upstream reservoirs we monitor are: 

Friant Dam (San Joaquin River)

Pine Flat Dam (Kings River)

Hidden Dam (Fresno River)

Buchanan Dam (Chowchilla River)

Merced Streams Group (multiple streams from "fill and spill" reservoirs in the foothills) are watched by observing the stream flows (see those locations under gaging stations).

To obtain information on releases, inflows, storage, and other pertinent information from these reservoirs, go to the California Data Exchange Center.

 The operator of Friant Dam, the US Bureau of Reclamation, provides a daily report, which can be obtained by going to :
