Grant County, Washington
Grand Coulee's irrigation miracle and the Gorge Amphitheatre — from the Columbia Basin Project's conversion of semi-arid shrub-steppe into Washington's most productive irrigated farmland to the Gorge Amphitheatre's basalt-walled outdoor concert venue (repeatedly voted the world's most beautiful concert venue), Moses Lake's water recreation, and a central Washington county where federal irrigation engineering created an agricultural abundance from desert landscape.

Parks & Recreation
PARKS & RECREATION
Key Assets: Grant County holds truly extraordinary geological history – Dry Falls, part of the Channeled Scablands, was once the site of the largest waterfall known to have ever existed on Earth: 3.5 miles wide and roughly 400 feet high, formed by catastrophic Ice Age megafloods when glacial ice dams repeatedly failed (evidence shows glaciers advanced and blocked the region as many as 85 times over the last 16,000 years); today Sun Lakes-Dry Falls State Park preserves the site, free admission (Discover Pass required for parking); the nearby Drumheller Channels, carved by the same floods, are designated one of only 8 National Natural Landmarks recognized in this category; Grand Coulee Dam, built 1933-1975, stands 550 feet tall with a 500-foot-wide granite base and a 30-foot-wide crest that carries a paved two-lane road – a nightly Laser Light Show runs May through September; construction of the dam and the Columbia Basin Project irrigation system (roughly 2,300 miles of canals/laterals) tripled the local population and established over 25 food processing plants, ultimately serving more than 550,000 irrigated acres and 6,000 farms by 1950, then the nation’s largest single reclamation project; during WWII, Moses Lake was home to Larson Air Force Base, a bomber pilot training facility, later decommissioned in 1965 and converted into the Port of Moses Lake/Grant County International Airport, which today serves as an active flight-training center for Japan Air Lines and other domestic/international carriers; the Grant County Historical Museum (open May–September) includes a restored historic village section; the Masquers Theater in Soap Lake, operating since 1979, is one of Washington’s oldest community theaters
Notes: Dry Falls’ status as the largest waterfall known to have ever existed on Earth is a genuinely, scientifically established geological fact – a truly remarkable natural history distinction for the county.

NOTES
Grant County holds genuinely extraordinary geological distinction – Dry Falls was once the site of the largest waterfall ever known to have existed on Earth, carved by repeated catastrophic Ice Age megafloods, and Grand Coulee Dam remains one of the most significant engineering achievements in the American West. The county’s Emergency Operations division has a distinctively broad structure, combining traditional emergency management with animal control, code enforcement, and specialized units (marine, ORV, mounted posse) reflecting its varied, large-scale terrain. All contact information above was sourced from official county, National Park Service, and shelter pages as of this writing; phone numbers and hours should be reconfirmed directly with the relevant office before a visit.
About Grant County
Grant County is the Columbia Basin Project in miniature – the story of how federal water engineering turned 500,000 acres of Washington desert into productive farmland, and what that productivity means at scale. Potatoes are the signature crop: Grant County consistently produces more potatoes than any other county in the United States, and the processing infrastructure that surrounds them – McCain Foods, Simplot, and other major processors – has built an industrial food economy in what was sagebrush steppe before the irrigation canals arrived.
The Grand Coulee Dam, which powers the irrigation pumps and provides electricity to the Pacific Northwest grid, lies just north of Grant County in Douglas/Okanogan counties – but the dam’s economic benefits flow most directly here. Moses Lake, the county’s largest city, is named for a series of lakes formed by the Crab Creek drainage in the coulee terrain, and the lake system draws recreation users who arrive in summer for water sports in quantities that the county’s relatively modest population doesn’t predict. Big Bend Community College provides higher education. Grant County’s demographics, like Franklin County’s, reflect the agricultural workforce immigration that has made the Columbia Basin one of the most Latino regions in the Pacific Northwest.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Grant County Superior Court 35 C Street NW, Ephrata, WA 98823 (509) 754-2011 / Clerk’s Office (509) 754-2015
Grant County is in Central Washington in the Columbia Basin, county seat Ephrata. Washington has NO separate probate court and has NOT adopted the Uniform Probate Code – probate is handled through the Superior Court in each county, under Title 11 RCW.
Step 1: figure out which path applies
Washington probate is entirely discretionary – the law does not require a probate proceeding to be filed after a death, regardless of whether there was a will. Probate is typically pursued only when the decedent owned real property titled solely in their name, or personal property exceeding the small estate threshold.
Small Estate Affidavit (RCW 11.62.010) – available when the decedent’s entire probate estate does not exceed $100,000 (personal property only, not counting the surviving spouse’s community property interest), and at least 40 days have passed since death. No court filing is required – the successor presents the sworn affidavit directly to whoever holds the asset. All debts must be paid or provided for first.
Nonintervention Powers (RCW 11.68) – Washington’s signature alternative to full court-supervised probate. If the estate is solvent, the Superior Court MUST grant the personal representative nonintervention powers upon request (unless the will specifically forbids it). Once granted, the representative can sell, mortgage, and distribute estate property, and ultimately close the estate by filing a Declaration of Completion – all without further court orders, notice to beneficiaries, or hearings.
Full/Supervised Administration – required only when nonintervention powers are denied or not sought, typically in contested or insolvent estates.
TEDRA (Trust and Estate Dispute Resolution Act, RCW 11.96A) – Washington’s framework for resolving probate, trust, and estate disputes.
Step 2: filing for administration
The person seeking to serve as personal representative files a petition with the Grant County Superior Court Clerk’s Office, along with the original will (if any) and a certified death certificate.
The court appoints the personal representative and issues Letters Testamentary (with a will) or Letters of Administration (without one).
The personal representative petitions for nonintervention powers, which the court must grant if the estate is solvent (unless the will forbids it).
Once granted, the representative pays debts, manages and distributes property, and notifies creditors, without further court supervision.
The estate is closed by filing a Declaration of Completion.
What it costs
Filing fees and probate costs vary by estate complexity; confirm current Grant County Superior Court fees directly.
Washington HAS a state estate tax, separate from any small estate affidavit or nonintervention process. For deaths on or after July 1, 2026, the applicable exclusion amount is $3,000,000 (RCW 83.100.020), with rates from 10% to 20%. There is NO portability between spouses.
The federal estate tax exemption is far higher, at $15,000,000 for a 2026 death.
