Explore Clark, 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 Clark, 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 Clark.
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.

Clark rises from the arid plateau of eastern Washington as a testament to the quiet endurance of the high desert. It lies 14.4 miles west-northwest of Lincoln, WA (from Lincoln, WA: bearing 298°T), and is situated 54.5 miles west-northwest of Airway Heights. The landscape surrounding Clark is defined by the expansive, shimmering presence of Franklin D Roosevelt Lake, which acts as the primary anchor for the local horizon. Only one mile away, the Columbia River carves its path through the earth, a constant, steady force that dictates the flow of the region. To the west, the distant silhouette of the Cascade Range looms as a faint, jagged promise against the sunset, while the rugged, sun-bleached topography of Speigle Canyon lies just four miles away, offering a stark contrast to the water-dominated lowlands.
Clark emerged from the confluence of frontier ambition and the monumental engineering projects that reshaped the American West during the twentieth century. The founding of Clark was inextricably linked to the massive transformation of the surrounding environment, as the creation of the reservoir forever altered how people inhabited this particular stretch of the interior. Life in Clark remains tethered to the rhythm of this history, where the legacy of regional development is visible in the very way the streets align with the water. The earth here holds the memory of those who first recognized the potential of the arid soil, their persistence hardening into the bedrock of the settlement that Clark continues to represent today.
Economic activity in Clark pulses with the seasonal demands of agriculture and the maintenance of the vital regional infrastructure. Because Clark falls entirely within the boundaries of the Lake Roosevelt National Recreation Area, the local economy is deeply influenced by the stewardship of the land and the management of water resources. Residents of Clark often find their livelihoods connected to the industries that support the surrounding agricultural expanse, as well as the administrative and maintenance roles required by the sprawling federal recreation area. While Clark does not house major universities, it remains a place where technical skill and practical knowledge are held in high regard, reflecting the pragmatic character of a region that relies on the strength of its power grids and irrigation systems.
Cultural life in Clark is marked by a deep, quiet appreciation for the natural world, with the Lake Roosevelt National Recreation Area serving as the primary stage for annual gatherings and community festivities. The people of Clark favor the rugged beauty of the inland plains over the frantic pace of larger urban centers, spending their weekends exploring the trails near Speigle Canyon or enjoying the stillness that descends upon the reservoir at dusk. While no singular professional sports team claims Clark, there is a fierce, localized loyalty to regional college programs that mirror the grit of the high desert. The true character of Clark reveals itself in the way the light catches the dust motes at the end of a long, dry day, illuminating a life that is simple, deliberate, and entirely at home in the vastness of the interior.

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.
