Agnew Irrigation District/Dungeness
Water Conservation Project (Funded 2004)
Current Status: Active
The
Dungeness River is listed on the Department of Ecology’s
303(d) list for both low instream flows and fecal coliform (fc) loading.
The proposed project involves pipelining five irrigation laterals (~38,205
ft) within the Agnew Irrigation District for the purpose of conserving
instream flows and improving instream habitat in the Dungeness River.
Enclosing open ditches with pipe eliminates ditch leakage, and thus reduces
the amount of water necessary to divert from the River for irrigation.
Upon completion of this project, an estimated 2.0+ cfs will be saved
(put back into the River) for instream flow habitat. A secondary benefit
of the project is to improve water quality by eliminating the pathway
for contaminants that enter the irrigation system at these ditch locations.
The ditches proposed for pipelining tail into Matriotti Creek, and ultimately
Dungeness River and Bay, and are highly suspected for fecal coliform
(fc) loading. Pipelining these ditches will ultimately reduce the amount
of fc loading to these water bodies. This proposal will benefit all salmon
stocks that utilize the Dungeness River and its tributaries. Specifically,
the project is aimed to increasing Dungeness River instream flow and
habitat for the three ESA-threatened species: Spring/Summer Chinook,
Summer Chum, and Bull Trout. This project is recommended in several watershed-planning
studies and reports, and is part of a larger community effort toward
salmon recovery and watershed restoration. |
