How to Use This Mattawa, Washington Map

This interactive map shows the street layout and satellite imagery for Mattawa, 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 Mattawa.

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.

About Mattawa, Washington

Mattawa is a locality in Grant County, Washington, United States. It has a population of approximately 3,335. The population density is 1396.6 people per km².

Mattawa claims a sun-drenched expanse of high desert, where the earth shifts in shades of sagebrush gray and dusty ochre under an immense, unyielding sky. It lies 22.5 miles west-northwest of Pierce, WA (from Pierce, WA: bearing 289°T), and is situated 4.1 miles north of Desert Aire. The landscape is defined by the stark, sculptural depth of Alkali Canyon, which carves a jagged path through the arid plateau only four miles from the center of the grid. To the west, the jagged, snow-dusted silhouette of the Cascade Range looms seventy-four miles away, a distant wall that traps the moisture and leaves this region to bake in the dry, intense heat of summer. At the edge of the local flora, Hund Memorial Park provides a quiet patch of managed green, offering a sharp contrast to the wild, wind-scoured plains that stretch toward the horizon.

Mattawa thrives as an agricultural outpost, drawing life from the nearby Columbia River, which flows three miles away to sustain the orchards and vineyards that define the regional economy. The rhythm of daily life here is dictated by the seasons of harvest, as labor and commerce align with the slow, steady cycles of fruit production that have transformed the dusty basin into a productive landscape. Beyond the reach of the irrigation lines, the land returns to its ancestral silence, punctuated only by the occasional flight of birds moving toward the water at Moran Slough. History here is written in the conversion of scrubland into rows of trellised vines and fruit trees, a persistence of human effort that turns the harsh, inland climate into a source of regional bounty.

About This Mattawa Map Page

This page provides an embedded street and satellite map of Mattawa, Washington. Coordinates: 46.73791, -119.902823. 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 Mattawa includes the ZIP code (99349), telephone area code (509), county seat of Grant County (Ephrata), and school district assignment (Wahluke 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.
