A brief history of the Roza Sunnyside Board of Joint Control
The Roza-Sunnyside Board of Joint Control (RSBOJC) is an umbrella
organization designed to administer joint projects of the Roza
Irrigation District (RID) and the Sunnyside Division Board of
Control (SDBOC). The RSBOJC, comprised of SDBOC Board members and
RID Board members, enables both entities to work cooperatively to
develop joint plans that address shared issues such as water quality
The driving force which led to the creation of the RSBOJC was water
conservation and quantity, due in part to the 1994 drought. With the
Department of Ecology's evaluation of the lower Yakima River in 1997
and enforcement of the Clean Water Act, considerable attention has
been focused on water quality issues.
In 1997, the Washington State Department of Ecology set a 90th
percentile (90% of measurements taken) Nephelometric Turbidity Unit
(NTU) target of 25 NTU by the year 2002 for all return flows to the
lower Yakima River.
In response, the RSBOJC adopted a
comprehensive Water Quality Policy designed to promote agricultural
and irrigation practices that decrease pollution and water use while
increasing water quality and conservation. Since the RSBOJC Water
Quality Policy was enacted in 1997, remarkable progress has been
made in the water quality of return flows to the Yakima River.

Although in recent years water quality issues have stolen some of
the thunder of the RSBOJC's conservation programs, the 2001 drought
has sparked renewed interest in water supply and conservation
