Posted: May 11, 2010Post Subject: UPDATE Canyon Creek and South Yuba Flows (5/11/2010)

Next Update 5/13/2010

Canyon Creek
On Saturday, May 15 through Monday, May 17 NID will release 200 CFS through the power house below Bowman Dam, resulting in 200 cfs plus accretion on lower Canyon Creek. It is possible that the release will continue past Monday.

On Saturday, May 22 through Monday, May 24, the release below Bowman into Canyon Creek will be 300 cfs.

See Dreamflows “Canyon Creek Below Bowman Lake” for flow information.

South Yuba
On Saturday, May 15 through Monday, May 17, the release below Spaulding will be 200 cfs, provided water is up on the gates (Look for update 5/13). After that the flow will probably go to 300 cfs.

Sometime during the next two weeks Spaulding will spill, and will spill 30,000 acre feet in May and June.

See Dreamflows “South Yuba At Lang Crossing” and “South Yuba at Hwy 49 Bridge” for flow information.

Flow Study Surveys
If you paddle any reach of Canyon Creek or the South Yuba in the next several weeks, please go to http://www.zoomerang.com/Survey/WEB2297AJ8Q9ZL
and fill out a boater survey. Survey information will be important in determining future flows in these reaches.

Next Update: 5/13/2010

Opportunistic Nature of Study Flows
NID’s most recent snow survey indicates 118% of normal snow pack. The recent PG&E snow survey showed an even larger snowpack. Both Bowman and Spaulding will spill, and the above releases are primarily driven by operational management of spill. For example, the 200 cfs and 300 cfs releases out of Bowman Lake will generate power with water that would otherwise spill.

Canyon Creek (SAME as last post)
On Saturday, May 15 through Monday, May 17 NID will release 200 CFS through the power house below Bowman Dam, resulting in 200 cfs plus accretion on lower Canyon Creek. It is possible that the release will continue past Monday.

On Saturday, May 22 through Monday, May 24, the release below Bowman into Canyon Creek will be 300 cfs.

Go to awetstate.com for a great video of Canyon Creek shot by Daniel Brasuell and Corey Tucker. The description of the run is also good: http://www.awetstate.com/

See Dreamflows “Canyon Creek Below Bowman Lake” for flow information.

South Yuba (CHANGED since last post)
The 200 cfs flow on the Yuba Gap reach is CANCELLED. The cooling trend decreased the flow at Cisco to 350 cfs and water will not be on the gates this coming weekend. If this flow cannot be scheduled before Spaulding spills, it may be possible to provide controlled study releases when the spill recession limb goes through 200 cfs, probably in June.

If the South Yuba natural flow trend continues to be 500-600 cfs, the Canyon Creek releases on Saturday, Sunday and Monday will bring all of the reaches below Washington to 700 to 800, or possibly somewhat higher.

Next Update 5/24/2010

Canyon Creek
175 to 200 cfs will be released into Canyon Creek through Thursday, May 20. On Friday, May 21 through Tuesday, May 25, and maybe beyond, NID will release 300 CFS into Canyon Creek.

Go to awetstate.com for a great video of Canyon Creek shot by Daniel Brasuell and Corey Tucker. The description of the run is also good: http://www.awetstate.com/

See Dreamflows “Canyon Creek Below Bowman Lake” for the release out of Bowman into Canyon Creek.

South Yuba
On Friday May 21 and Saturday May 22 PG&E will release 250 cfs from Spaulding Dam. On Sunday, May 23 the flow is likely to increase.

On Friday and Saturday, the flow in the South Yuba below Washington is likely to be 900 cfs to 1100 cfs. On Sunday the flow is likely to increase to 1200 to 1500, or more. Beyond Sunday, Spaulding will be spilling, and flows will go higher and will be unpredictable.

Opportunistic Nature of Study Flows
Flows out of Lake Spaulding are primarily operational measures to manage spill, adjusted to provide for whitewater boating study flows.
