Pending Water Right Applications
Ecology uses the Water Right Tracking System (WRTS) to track the progress
of water right applications and permits. Use the map to find water
right application on file with Ecology. A tabular view of all pending
water right applications is available at:
Pending Water Right Applications in Washington State.
Includes both applications for new water rights and to change
existing water rights. Updated weekly . Using the filter
options on the right sidebar, you can filter applications by
County Name, Watershed Name, Year of Application, Purpose of
Application, etc. For example, enter “Thurston” in the County
Name field while checking the box next to it and the dataset
will refresh to display only applications in Thurston County.
Other filtering and visualization options are available as well.

KEY (to column headings on reports)
- WRIA Code: Washington state is divided into 62 Water Resource
Inventory Areas, known as WRIAs, based on geographic drainage systems.
- Control number (reading from left to right): C refers to change, G
refers to a ground water application, S to a surface water application, and
R for reservoir; the first number refers to which regional office the
application was filed: 1=Northwest regional office in Bellevue; 2=Southwest
regional office in Lacey; 3=Eastern regional office in Spokane; and
4=Central regional office in Yakima; the last five digits are the control
number assigned to a new application.
- Business/Person Name: the name of the person or business applying
for the water right; this could be the property owner, or a developer, or
some other involved party.
- Priority Date: the date the application was filed with the
Department of Ecology.
- Q(i) (Instantaneous Quantity): the maximum diversion or withdrawal
rate requested by the applicant; in cubic feet per second for surface water
and gallons per minute for ground water.
- Q(a) (Acre Feet/Year): the annual volume or quantity of water
requested by the applicant; one acre foot per year is equal to one foot of
water over one acre of land or 325,850 gallons of water.

control, flood control, or any water use which improves or maintains the
quality of the environment)
- FP-- Frost Protection (frost protection other than cranberries)
- FR-- Fire Protection (includes sprinkling log storage

reservoirs, hatcheries, and all other facilities involved in the overall
purpose of fish propagation)
- HE-- Heat Exchange (use of such equipment as heat pumps,
refrigeration equipment, and other cooling devices)
- HP-- Heat Protection For Crops (Water used during the summer
months to protect such crops as apples and cranberries from the heat.)
- HW-- Highway (maintenance and construction)
- IR-- Irrigation (includes cranberry farming, lawn/garden
watering with definite acreage, golf courses, greenhouses, etc.)
- Iflow-- Instream flow

- TW-T-- Trust Water-Temporary (Water in a temporary trust.)
- UN-- Unknown
- WL-- Wildlife Propagation (includes water to service
non-domesticated animals such as birds, game and non-game species)
- Source: what source of water the supply is coming from. For
surface water, this states the name of the water involved (river, stream,
spring, etc.). For ground water, this states the type of source (well,
