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 information please call
