Keeping water in the Spokane River is a priority for all of us. We all want a clean and flowing river.
For the Spokane River, timing of water availability is the key issue. The river depends on groundwater from the aquifer for flows in late summer and fall, at the same time human use from the aquifer is at its highest.
Population in the region is increasing while river flows are decreasing. Washington has started putting tools in place to adequately protect the river and its associated benefits, such as hydropower, recreation, and wastewater management.
One important tool for protecting streams is to establish stream flow levels in regulations or “rules.” Ecology has adopted an instream flow rule for the mainstem of the Spokane River. The rule gives the Spokane River a water right, much like we give individuals, farms and municipalities. The rule applies to the Spokane River and that portion of Spokane County within the boundary of the Spokane Valley-Rathdrum Prairie (see map at bottom of page).
We can have a healthy river with enough water to meet all the various needs and demands placed on it, with careful management.
Stream flows are the amount of water flowing down a river or stream. Instream flows are stream flow levels set in rule. The Legislature assigned Ecology the job of adopting rules to protect and preserve sufficient water in streams for “instream resources” including fish, wildlife, recreational uses, water quality and livestock watering. Rules that protect stream flows by establishing instream flows are known by the shorthand “instream flow rules.”
Instream flows are specific levels of stream flow (measured in cubic feet per second, cfs) that are determined scientifically to be necessary for a healthy stream. The instream flow levels vary month-by-month, as flows naturally do.Hide this content.
Instream flows are the stream flow levels needed for a healthy stream. Once adopted in rule, instream flows are water rights that must be protected from harm (impairment) by future withdrawals. Instream flows also become the regulatory flow threshold used by Ecology to determine whether there is water to withdraw for new uses while still protecting fish and other instream resources, and senior water rights.Hide this content.
Not entirely. It would set a benchmark to measure against, and it would prevent new authorizations of water rights from harming flows. There are existing water rights which, if fully used, could and likely would contribute to declining river flows. Setting instream flows by rule does NOT require people to put water in streams.Hide this content.
Fish biologists experts from Ecology and the Washington Department of Fish and Wildlife (WDFW) reviewed all available data, including the most recent fish spawning studies conducted by Avista Corp., to identify the flows needed for healthy fish populations. Those studies considered habitat needs for mountain whitefish and redband trout, species native to the Spokane River. The proposed instream flows are generally consistent with flows recommended in Avista’s license to operate, which was renewed in 2010 by the Federal Energy Regulatory Commission.Hide this content.
Many detailed reports and studies have been completed and support establishing an instream flow rule. These include:
A bibliography of studies is available on Ecology’s website at: http://www.ecy.wa.gov/programs/wr/rules/557-res.htmlHide this content.
An instream flow rule is essentially a water right for the river. Wells in use prior to the effective date of the regulation are considered “senior” to the instream flows. Therefore, wells in use prior to the rule are not affected by the rule. The rule affects future potential water withdrawals, not existing ones.
Withdrawals from the Spokane Valley-Rathdrum Prairie Aquifer approved after the rule is established would be interruptible if flows in the river fall below those specified in rule. However, the majority of the region is served by existing water purveyors with adequate water rights to meet future expansion and development demand.Hide this content.
Current analysis of the proposed rule area shows that there are very few parcels of land that are not currently within the boundaries of existing water providers. For the rare cases where someone could not connect to an existing water purveyor in a reasonable and timely manner, Ecology is already working on providing a solution to ensure the few new permit-exempt uses in the rule area can proceed.
|Permit-exempt well: The state Ground Water Code allows for certain uses of small quantities of groundwater without obtaining a permit from Ecology. (RCW 90.44.050)|
Continued use of existing senior water rights would not be affected by the rule. Municipal water purveyors could continue to expand into unused water rights or portions of water rights.
One potential effect could be that some of the existing water rights held by public water purveyors may need to be shared among purveyors that don’t hold large enough water rights to meet their future demand. This is a common practice. Currently, there is an adequate supply of water held by municipal suppliers for future growth and development.
The rule may affect water right holders that make future changes to their water right, such as where water is applied or withdrawn or the transfer of ownership of a water right.Hide this content.
Currently there are 24 applications waiting to be processed, requesting a total of 117 cubic feet per second of water be made available from the aquifer in Washington. Ecology cannot act on these requests without having an instream flow rule in place. Established instream flow levels will let Ecology know what water can be used out-of-stream while still preserving the river and instream resources, and senior water rights.Hide this content.
An instream flow rule, which is required under state law, is designed to protect instream resources, including fish, wildlife, recreation and water quality. A rule would also help protect existing water rights including rights held by municipal water purveyors and Avista for hydropower generation. All these uses, which are part of our local economy, would suffer without adequate flows in the river.Hide this content.
Ecology is required by law to write several economic analyses when adopting a new rule. Benefits must exceed the costs before a rule can be adopted. We must also determine that a proposed rule is the least burdensome alternative for those required to comply.
New state regulations are required to ease disproportionate impacts to small businesses as much as possible. Prior to rule adoption a “Small Business Economic Impact Statement” must be prepared.
The rule would not establish fees or requirements that local businesses, individuals or cities would have to pay or meet. The rule would not impose any regulatory changes on existing water right holders, although it may impact changes or transfers of those rights made after the rule becomes effective.
A potential impact could be that new water rights from the river and the Washington side of the Spokane Valley-Rathdrum Prairie Aquifer would be restricted or interruptible (not consistently available year-round). However, existing municipal suppliers have ample water to meet new demands far into the future.Hide this content.
An instream flow rule does not add water to the river; rather it protects flows from new withdrawals in the future. Wastewater discharges help maintain flows in the Spokane River by returning water that was originally withdrawn for municipal water supply. It is true that removing discharges from the river could negatively impact the ability of the river to maintain habitat, particularly if discharges are removed outside of the aquifer. However, it does not change our obligation to protect the river and its flow.
A clean and flowing river is a priority for all of us. With foresight and creative solutions we can work together to improve water quality and protect flows in the river.Hide this content.
In short, it would not. Legally, our instream flow rule would not prevent Idaho from issuing new water rights from the Spokane Valley-Rathdrum Prairie Aquifer.
The Spokane Valley-Rathdrum Prairie Aquifer and the Spokane River are a shared resource between Idaho and Washington. While both states have tools to manage water resources in a way that benefits local communities, Idaho and Washington regulations are separate and distinct and legally cannot impact the other.
In the event of interstate legal conflict over water, each state has interests. Idaho has set lake levels for Lake Coeur d’Alene, issued an instream flow water right for the Idaho portion of the Spokane River, and is adjudicating water rights in the Spokane River drainage.
Washington has not started adjudication in the Spokane River Basin due to state budget constraints. The first step in establishing Washington interests in this basin is setting instream flows for the Spokane River by rule. Once in place, Ecology will be able to better manage our shared water resource.
|Adjudication: A legal process to determine who has a valid water right, how much water can be used, and who has priority during shortages.|
This rule would only affect new withdrawals from the aquifer and the Spokane River; it wouldn’t affect new withdrawals that impact the Little Spokane River. There is already an existing instream flow rule for the Little Spokane River, Water Resources Inventory Area 55 (Chapter 173-555 WAC). However, because the Little Spokane River watershed overlaps with the aquifer, Ecology is concurrently proposing a narrow amendment to the Little Spokane River rule to clarify the application of each rule in the area of the overlap.Hide this content.
