Explore Coulee Dam, Washington, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Coulee Dam, 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 Coulee Dam.
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.

Coulee Dam commands a rugged expanse where the Columbia River carves a deep, basalt-lined path through the arid plateau of the inland northwest. It lies 13.5 miles west-northwest of Clark, WA (from Clark, WA: bearing 281°T), and is situated 27.6 miles west-northwest of Lincoln. The landscape surrounding Coulee Dam is defined by the stark, sun-bleached geometry of the canyon walls, which rise abruptly from the riverbed to meet a vast, open sky. To the west, the distant, jagged silhouette of the Cascade Range anchors the horizon, while the immediate terrain is broken by the steep, shadowed creases of Wallace Canyon. Here, the earth feels ancient and exposed, with the shimmering, expansive waters of Franklin D Roosevelt Lake stretching behind the great concrete barrier, held in place by the weight of human ambition against the relentless flow of the river.
The history of Coulee Dam remains inextricably linked to the massive engineering feat that transformed the region, turning a dry, high-desert corridor into a vital engine for the regional economy. Beyond the industrial scale of the power generation, the proximity of Rufus Woods Lake provides a sanctuary for those who seek the quietude of the dry scrublands and the slow, deliberate pace of life in a place defined by its utility. During the long, golden hours of dusk, the light catches the gray stone of the hills, softening the harsh edges of the geology and revealing a quiet, persistent beauty in the dust and sagebrush. Life in Coulee Dam persists in the shadow of this monumental architecture, where the hum of the turbines serves as a constant, low-frequency pulse beneath the stillness of the high-desert air.

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.
