The prominent diversion from the Scott River in Scott Valley is the Scott Valley Irrigation
District (SVID) ditch. This ditch is used for irrigation and stockwater. The Scott River
is an important spawning tributary for fall chinook salmon and steelhead trout. During
the past ten years (1985-1995) the Scott River fisheries, as well as other users, has been in
a serious declining state. One of the reasons has been continued drought conditions and
low flows in the Scott River.

Being the largest diversion from the Scott River, the SVID initiated a study to determine
the feasibility and desirability of converting the SVID water source from a surface water
diversion from Scott River to a ground water supply. The basic premise was to use
underground sources of water for stockwater requirements in order to leave more surface
water in the river during low flow periods that are critical for anadromous fish. The study
included a survey of all SVID users to help determine the extent of use of SVID water,
collect opinions of users, and address the many questions and speculation regarding water
rights and anadromous fisheries. The objectives of the study were to promote constructive
and cooperative attitudes, determine feasibility of an alternate stockwater source, and
provide information that could possibly lead to a plan that would mutually benefit water
users and fish habitat.

The study revealed many diverse opinions and concerns. The opinions ranged from being
satisfied with the current operation to changing the SVID to ground water supply for both
stockwater and irrigation and included the possibility of selling diversion during certain
periods to enhance the surface flow in Scott River. The major concerns focused on costs,
water rights, severe leakage in the District ditch, and sealing problems associated with the
ditch being dry for extended periods of time.

Basic costs for potential alternative stockwater wells were determined, sources of funding
explored, and avenues of legal and technical assistance were established.
The specific data and results of the study have been detailed within the body of this report.
This study has been reported to the SVID Board of Directors for review. I t is appropriate
that a final plan or course of action can be determined only after review and approval by
the SVID Board and members.
