How to Use This Grand Coulee, Washington Map

This interactive map shows the street layout and satellite imagery for Grand Coulee, Washington. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of Washington or beyond.

Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).

TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Grand Coulee.

Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.

Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Grand Coulee occupies a stark, sun-bleached expanse where the high desert plateau meets the expansive, deep waters of Crescent Bay. It lies 14.6 miles west of Clark, WA (from Clark, WA: bearing 274°T), and is situated 28.3 miles west-northwest of Lincoln. The landscape is defined by the immense, basalt-walled scar of the ancient earth, a dry, rugged theater where the light of late afternoon turns the jagged cliffs into bruised shades of violet and ochre. Only one mile away, the Columbia River channels the lifeblood of the region, its steady, powerful current carving through the arid silence. Nearby, the dramatic descent of Martin Falls offers a sudden, crystalline interruption to the dry terrain, while the looming presence of the Cascade Range remains a distant, snow-dusted silhouette against the western horizon. Within the borders of the Lake Roosevelt National Recreation Area, the land holds a quiet, austere beauty, where the wind carries the scent of sagebrush across the vast, open plains that stretch toward the jagged mouth of Rattlesnake Canyon.

Grand Coulee remains inextricably linked to the monumental engineering efforts of the mid-twentieth century, which transformed the local economy and redirected the flow of the regional landscape. The presence of the massive concrete dam serves as a constant, industrial pulse, grounding the daily rhythm of life in the labor of maintenance and the management of water. This history of industry has shaped a culture of resilience, where the inhabitants have adapted to a climate of extremes, finding comfort in the steady, predictable patterns of the seasons. Visitors often gravitate toward the recreation opportunities offered by the expansive water, yet the true character of Grand Coulee is found in the quiet, dusty streets and the stoic endurance of those who call this high-desert plateau home. Life here moves with a deliberate, measured pace, reflecting the gravity of the surrounding stone and the immense, unyielding scale of the desert sky.

About This Grand Coulee Map Page

This page provides an embedded street and satellite map of Grand Coulee, Washington. Coordinates: 47.941541, -119.003355. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Grand Coulee includes the ZIP code (99133, 99116), telephone area code (509), county seat of Grant County (Ephrata), and school district assignment (Grand Coulee Dam School District).

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.

Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
