FORT JONES- The North Coast Regional Water Quality
Control Board staff will be on hand to discuss how
water quality measures will be implemented in our
community at the Scott River Watershed Council
meeting on Tuesday, October 17. The meeting will
be held at the Fort Jones Community Center at 7
p.m. and is open to all concerned community
members.
The Regional Water Board is coming to Scott Valley
to discuss the recently released "TMDL" draft work
plan for the Scott River Watershed. The TMDL,
which stands for Total Maximum Daily Load,
addresses water quality factors impairing the
Scott River. The amount of sediment in the river,
and the high water temperature are the issues
which are being addressed by the work plan.
The TMDL work plan proposes to have the Council
(as well as the Siskiyou Resource Conservation
District) enter into a Memorandum of Understanding
(MOU) with the Regional Water Board on several
issues. To help reduce stream temperature, they
want a strategy and schedule for riparian
vegetation protection and restoration. Related
recommendations want the Council to address bank
stabilization projects and livestock grazing that
could harm riparian vegetation.
Sediment and water temperature continue to be a
focus of the Scott River Watershed Council and its
partners. Currently, there are several studies
underway, which monitor temperature and sediment.
Research by the Siskiyou Resource Conservation
District includes collecting and calculating
sediment samples. Using a method known as McNeil
sampling, the RCD staff takes a sample of rocks,
fine sand and sediment and calculates the relative
amount of sediment in spawning areas. This effort
first began in 1989. Through the use of another
method called V-Star, the RCD with the US Forest
Service have calculated the amount of sediment in
pools. V-Star is done by measuring the volume of
sediment as related to water in residual pools.
Temperature gauges have been installed and
monitored in the watershed to track the
temperature in the Scott River and tributaries.
This collaborative monitoring effort has been
ongoing since 1985.
Since March, 2006, the Watershed Council has
collected monthly static well level (water table)
data with confidentiality paramount in the
research plan. The TMDL draft work plan can be
found at www.waterboards.ca.gov. The work plan
identifies several areas in which the Watershed
Council is being asked to formalize their strategy
and enter into agreements with the Water Board.
Among the issues are the water quality impacts
associated with grazing, restoration of
vegetation, which provide shade to the waterbodies,
water use, and flood control and bank
stabilization.
The watershed community has worked diligently to
protect our resources and lifestyles. It is time,
once again, that we come together to insure that
the Water Board's proposed work plan is a plan
that works for the Scott River Watershed For more

Watershed Council Coordinator at (530) 467-4007.
