Chapter 173-557 WAC
Water Resources Management Program (WRMP) for the Spokane River and Spokane Valley Rathdrum Prairie (SVRP) Aquifer and amendment to WAC 173-555-010
Overview of Rule Making
We are proposing an instream flow rule to protect the Spokane River.
The purpose of an instream flow rule is to protect and preserve water
in streams for “instream resources” including fish, wildlife,
recreational uses, wastewater management, and hydropower. The
legislature gave us the responsibility to protect rivers and streams
with an allocation of water set by establishing instream flow rules.
The rule will apply to the mainstem of the Spokane
River and those portions of Spokane River and those portions of the
Spokane and Stevens Counties within the boundary
of the Spokane Valley Rathdrum Prairie Aquifer.
Once an instream flow is set Ecology will use the rule as a regulatory flow
threshold to determine whether there is water to withdraw for new uses
while still protecting fish and other instream resources.
making proposes a new rule for the Spokane River and Spokane Valley
Aquifer. The Little Spokane River has an instream flow rule in
Chapter 173-555, adopted in 1976. Geographically, part of the
new proposed rule area overlaps the Little Spokane River rule area.
To clarify how each rule applies to new uses of water in the area
where the two rules overlap, an amendment to WAC 173-555-010 is being
proposed as part of the same rule making process for the new rule.
The only section of WAC 173-555 under consideration for amendment is
010, the general provision that addresses applicability of this rule.
Ecology is not considering amendment to any other parts of the rule.
Input on other sections of this rule will not be considered in the
context of this rule making.
