New Flows For the San Joaquin

On Thursday April 12, 2007, California Stewardship Director Dave Steindorf and AW volunteer Paul
Martzen, attended the signing ceremony for the Big Creek Settlement agreement on the Southern
California Edison (SCE) projects of the San Joaquin River. Steindorf, who was asked to speak at
the event, said "We applaud Southern California Edison's willingness to combine these projects into
a single relicensing process". With over twenty reservoirs, forebays and diversions the four
separate FERC licenses encompassed in the Big Creek relicensing make up the largest geographic area
of any project that has been relicensed in California. "SCE has saved years and millions in
ratepayer dollars by relicensing all of the projects in this watershed at one time".
American Whitewater has worked diligently with Sate and Federal Agencies to restore a more natural
flow regime on the San Joaquin River. It has been our goal to create new flow conditions on the
San Joaquin for these projects that will benefit both the aquatic ecosystem and river
recreation.
The best example of flows that are good for boaters and biota are the channel maintenance flows,
which will occur in the spring. These flows will occur on the Florence Lake to Mono Hot Springs
run on the South Fork of the San Joaquin between June 1 and July 7th. During Wet years these flow
will last for at least 13 days and have flow between 500 and 700 cfs for at least five days. In
Above Normal Water Years, flows in the same range will occur for a minimum of four days.
Pre-spill releases will provide additional boating opportunity below Mammoth Pool Reservoir. These
pre-spill releases will correct the problem that has plagued Whitewater boater in this basin for
years. Even in wet years little boating opportunity has existed on this project because flows will
typically change from too low up to level that are too high in a very short time. By releasing
water ahead of spill events paddlers can take advantage of this more gradual up ramp on the
whitewater runs below Mammoth Pool. We also believe that these more gradual flow increases are
more protective of the ecosystem.
Probably the biggest impediment to boating on any river is being able to know what the flows are
while you are still sitting at home. Driving an hour or more to a river just to find that the
flows are too low or too high is an expensive proposition. Fortunately, SCE has not only agreed to
provide flow information but they have agreed to do it now! Gauges for both the Florence to Mono,
Tied For First, as well as several other runs are now on the AW river pages. We appreciate SCE
providing this information ahead of the new license. If they had chosen to wait until the new
license was issued we could be waiting several years to get real-time flow information on these
runs.
This is the third settlement that AW Stewardship Director Steindorf has signed this year, a
remarkable achievement given that each of these processes takes at least seven years to complete.
AW has been involved in more than 15 hydro projects across the state in the past ten years, this
is more than any other non-profit in California. While we have signed some landmark agreements in
these past ten years, some of the most important river resources in the state have yet to go
through this process, including, the Yuba and McCloud Rivers. We also have spent a tremendous
amount of time protecting the agreements that we have already made, on rivers such as the Feather
and the Pit. Without your support, future victories and maintaining ones from the pass will not be
possible. Please send your support and the support of anyone who love's rivers, and we will keep
getting it done.
