The second largest Coho run on the Scott in redecent years is good news but
the numbers Sari shared indicate that we are not making progress in
rebuilding the Scott Coho population to anything near biological viability
over the long run. To give raders a more complete view perhpas Sari or Tom
will share a full data set for the last 10 years, i.e. the ¨bad¨years as
well as the ¨good¨ - so that folks get a more comlete picture. 

The dewatering of the Scott and key tribs each summer is likely the top
factor preventing recovery of Scott Coho to long-term viability. Very few of
the progeny of this year´s relatively ¨good¨ run will make it to the ocean.
Many will be killed by dewatering below irrigation diversions and others by
Klamath mainstem conditions.  A multi-year deep drought could still wipe out
Scott Coho. We remain on the edge of functional extinction. Until SWRCB
begins or is forced to actually measure and regulate diversions and
groundwater pumping Scott Coho will remain on the brink of extinciton. 

Those who work to ¨protect¨surface and groundwater irrigators from
regulation are an impediment to recovery.

Scott River Coho run largest since 2007
PHOTO/ PHOTO COURTESY CALIFORNIA DEPARTMENT OF FISH AND WILDLIFE
The Shasta River video weir, located close to the Klamath River, was damaged
on Dec. 9 by the icy conditions in the river.
After a large influx of Coho salmon in the past few weeks, the Scott River
has seen its largest return of the species since 2007.?
The latest data from the California Department of Fish and Wildlife video
weirs on the Klamath?s tributaries shows a relatively strong return this
year for Chinook and Coho, with the Scott?s Chinook numbers as of Dec. 10
coming in just under the seven year average weir data. Final counts for the
Scott also rely on carcass and spawning area counts, which have not yet been
finalized.?
On Bogus Creek, the numbers of Chinook and Coho passing the video weir have
trickled to a halt, with only one Coho returning between Dec. 4 and Dec.
10.?
So far, the Bogus numbers are 3,143 Chinook and 290 Coho, which the data
shows is the strongest Coho return since 2004 and the third-smallest Chinook
return in that same time period.?
The end of season for the Shasta counts was called on Dec. 10, due to ice
floes damaging the weir on Dec. 9. The Chinook count came in at 8,127, the
third-largest return since 2001, with 151 Coho, the highest number of that
species since 2007.?
The Scott and Bogus weirs are still operating, according to
CDFW?environmental scientist Morgan Knechtle, and once the final numbers are
compiled and finalized, they will be used in forecasts for 2014.

What was missing from the article was the actual number of coho seen at the
weir at RM 18 on the Scott River: 1,264 adults as of 12/18. Final figure
won?t be available until after the weir closes in early January and the
downstream estimate is added in.

For this same brood year, the recent figure compares with the final weir
counts of 911 in 2010 and 1,622 in 2007.
