We are sampling approximately 20
sites in 2020 throughout the Kittitas
Valley to demonstrate continuing
improvements and compliance with
Washington State Department of
Ecology's Water Quality Cleanup Plans
(formerly known as TMDLs).
Kittitas County Water Purveyors
Besides our weekly sampling routine,
we are coordinating with other
agencies using continual measuring
devices. These measure water quality
throughout the season, catching events
like late-night thunderstorms whose
effects we might other miss.
KCWP Advisory Committee meetings
Advisory Committee meetings are held on an
as-needed basis, generally four times a year.
If you would like to address the committee,
please contact us to be included on the
Elementary Ag Day
Third graders from all of Kittitas County come
to the Kittitas Valley Event Center
(fairgrounds) to learn about the important
role agriculture plays in our county's
economic structure. They also learn about
the source of the food they eat, the milk they
drink, the importance of water quality, and
why soil health is so vital.
Naneum, Wilson, and Cherry Creek Assessment
Working with multiple agencies and stakeholders on an assessment of existing conditions in the
Naneum, Wilson, and Cherry Creek watersheds to develop long-term management plans
addressing floods, infrastructure, fish habitat, and irrigation.
Voluntary Stewardship Program
Washington State's Voluntary Stewardship Program (VSP) was created in 2011 to provide an
alternative approach for counties to address Growth Management requirements for agricultural
activities. Kittitas County Conservation District, by appointment of the Kittitas County
Commissioners, is directing the program. KCWP is working with the KCCD to promote and protect
irrigated agriculture's interests. More information about VWP can be found here: KCCD VSP.
Upper Yakima River Basin Suspended Sediment and Organochlorine Pesticide TMDL
Weekly sampling and long-term monitoring are providing us with data/information to make
necessary improvements to management practices and infrastructure to increase irrigation
water quality where it intersects with natural streams and with the Yakima River.
Upper Yakima Tributaries Temperature Reduction Plan
Working with Ecology, water temperature measurements are taken throughout the valley.
Limited streamflow, high summer air temperatures, and narrow riparian borders limit how cool
local creeks can be. Irrigation canals tend to be cooler as they convey more water through deeper
Wilson Creek Sub-Basin Bacteria Total Maximum Daily Load
Fecal coliform bacteria have been found in exceedance of State standards in the Wilson Creek
Sub-basin. While fecal coliforms are generally not harmful to humans, there are subsets that are
extremely dangerous, including E. coli. Keeping livestock and associated manure away from
streams is an important step in decreasing bacterial counts. Birds (especially waterfowl) and
wildlife are perhaps even more significant contributors of coliforms, however, and their
management is outside our scope.
