Walla County irrigators are leading the way by taking steps
to conserve water resources. Low river flows that affect endangered
species can impact agricultural irrigation. In an effort to
maintain area irrigation and avoid regulatory mandates, the
Conservation District offers cost-share to irrigators who
want to improve their irrigation systems and reduce water
loss. Water saved through greater efficiency is placed in
trust and left in the river. These projects result in continued
irrigation using less water.
The Gardena Farms Irrigation District piping project, completed
in 2002, saves an estimated 650 gpm (gallons per minute) during
the irrigation season. Other projects have converted flood
irrigation and leaky handlines to state-of-the-art pivot systems.

In 2005 the District received a grant to help irrigators convert
water-wasting open irrigation ditches to buried pipelines.
With new piping, every drop of conveyance water will reach
the intended crops. During times of high river flows, water
will be diverted down perforated pipes to help recharge our
falling aquifer. Our project partners include the Walla Walla
Community College Irrigation technology department and various
funding sources (see Links.)
