Water Quality Improvement
Deschutes River Watershed Area:
Deschutes River, Percival Creek, and Budd Inlet Tributaries
Living in the Deschutes watershed offers an abundance of beauty and
water-related activities. Unfortunately, the quality of water in some
areas of the Deschutes River and other creeks, are below
state standards. In order to return the river to a healthy condition
Ecology, along with local government and other
interested groups, is engaging in a coordinated process called a
total maximum daily load,
or TMDL project.
Water quality issues
The Deschutes River is under pressure from growth, resulting in many
small, uncontrolled sources of pollution entering the river. Local city,
county, and state government agencies work hard to monitor and protect
the quality of our water. Water quality monitoring revealed that
levels of pH, dissolved oxygen, temperature, fine sediment, and
fecal coliform were not normal, therefore triggering the “TMDL” process.
See map of the TMDL project area.
Status of the project
Ecology, with the help of an advisory group of affected stakeholders,
special interest groups, and interested citizens, worked to develop a plan
to solve these pollution problems. The
Deschutes River, Percival
Creek, and Budd Inlet Tributaries Water Quality Improvement Plan (also known
as a Total Maximum Daily Load or TMDL) assigns the amount of pollution the waterbodies can receive and still meet water quality standards. Any
additional amount needs to be reduced or eliminated to achieve clean water.
This plan provides a framework for how the stakeholders will track, monitor,
and implement the water cleanup plan. It outlines what is needed,
establishes a schedule, and guides corrective actions with adaptive
plan was available for public comment period April 13 through May 27, 2015.
Ecology held two public meetings to provide a broad
overview of the project and findings.
Ecology staff finalized the
in December 2015 submitted it to the U.S.
Environmental Protection Agency (EPA).
