Klamath TMDL in a nutshell
(Sorry to timber folks. I was limited in space.)
by Siskiyou County Supervisor Marcia Armstrong 7/3/09
The proposed Klamath TMDL (Total Maximum Daily Load) water quality
implementation plan imposes yet another wave of regulations on the
ability of locals to make a living in Siskiyou County. It further
burdens all ranchers, timber managers, irrigated agriculturalists,
suction dredge miners and anyone with a road in the Klamath River
basin in Siskiyou County. (This includes the Scott and the Shasta
Valleys.)
Miners will see substantial new restrictions. No dredge “instream
buffer areas” of from 300-1500 feet will be established at the
confluence of creeks and streams tributary to the Klamath. (These
buffers will be upstream and downstream on the Klamath River and
up into the tributary.) This is to protect cold water “thermal
refugia” for salmon.
There is also a full slate of regulations on timber management.
The current waiver for Waste Discharge Requirements (WDRs) for the
Shasta TMDL is conditional upon increasing dedicated instream cold
water flows by 45 cubic feet per second (cfs.) The WDR waiver for
the Scott recommended a cooperative groundwater/surface water
study plan. The Klamath TMDL enlarges that to include the
completion of the actual study and the implementation “appropriate
management practices…in order to ensure adequate flow in the
river.”
A section of the Klamath TMDL imposes a new set of
“watershed-wide” requirements to prohibit streamside tree removal
and prohibit sediment discharge. (Residential landowners will be
largely covered under existing restrictions.)
Land owners will need to establish “riparian management zones,”
“streamside buffer areas,” or “watershed and lake protection zones”
large enough to “include any trees that have the potential to
provide shade to surface waters once they reach their site
potential height.” These trees should not be removed, and where
they have been removed, may need to be replanted.
Those with existing sediment sources, such as roads, will have to:
(1) Identify and quantify sediment sources; (2) Prioritize
efforts to control the sources based on magnitude of threat,
feasibility of control and accessibility; (3) Set a schedule for
cleanup; (4) Take action; (5) Monitor effectiveness and adapt.
Land managers on this path will be considered on the path to
compliance. Non-compliance would invite enforcement pursuant to
the Statewide Enforcement Policy.
Under the watershed-wide prohibitions, grazers must protect
riparian shade and control discharges of nutrients and organic
matter. NCRWQCB staff is recommending a WDR conditional waiver to
cover grazing activities and limit livestock access to riparian
areas.
The TMDL recommends that grazers have Ranch Water Quality
Management Plans (RWQMP) to address problems. (These may be
required under a WDR or waiver.) The RWQMP identifies the
management practices selected by the landowner(s) to comply with
the TMDL and also include elements such as: (1) a sediment source
survey; (2) implementation measures and schedule; (3) an inventory
of riparian conditions; (4) Nutrient and organic matter control
measures; and (5) Effectiveness tracking
According to the TMDL, irrigated agricultural users have the
potential to contribute to water quality impairments through
discharges of polluted irrigation tailwater and by degrading
riparian conditions. Watershed-wide WDRs are proposed for
individual or group compliance. (These would succeed existing
waivers in the Shasta and Scott.) The requirements would include
compliance with best management practices (BMPs) that: (1) Control
discharges resulting from irrigated agriculture activities; (2)
Comply with the prohibition on the discharge of excess sediment;
and (3) meet the TMDL allocations and targets for shade,
nutrients, and organic matter. Management measures should focus on
maintaining and restoring riparian vegetation, road management to
control sediment discharges, and controlling irrigation tailwater
quality. It is envisioned that a WDR waiver could involve
implementation through Water Quality Management Plans, similar to
the RWQMPs.
The implementation plan was just released as a new part of the
TMDL. Unfortunately, the local Yreka workshop on July 7 will have
passed at the time of publishing. Additional workshops will be
held in Orleans (Karuk offices) on the 8th and in
Klamath on the 9th (Yurok offices.) Comments must be
submitted to the NCRWQCB by August 17.
