Built only from the data on this page: official access lists, OpenStreetMap beaches and trails, campground listings, state and USGS invasive-species records. We don't rate crowds or water quality.
Stocked by the state: Brown trout, Rainbow trout (2015–2026, 12 years; 219,315 fish in all, fry included)
Source: Washington Department of Fish and Wildlife, WDFW Fish Plants data on data.wa.gov (releases into Lake Sacajawea, Cowlitz County, since 2015). See WDFW trout stocking reports. These are stocking records, not a full fish survey; other species also live here.

Shoreline: USGS National Hydrography Dataset (NHD Waterbody, Permanent ID 164345764), public domain. State outline: U.S. Census Bureau TIGERweb. Points: WDFW water access sites and OpenStreetMap boat ramps (ODbL). Dashed trails: © OpenStreetMap contributors (ODbL). Interactive map: Leaflet with © OpenStreetMap contributors. Not for navigation.
OpenStreetMap shows about 6.6 mi of public hiking and walking trail within about 90 m (300 ft) of the Lake Sacajawea shoreline. Together the trails go all or nearly all the way around Lake Sacajawea, staying close to the water. About 0.2 mi of it is on islands, which you can reach only by boat.
No trailhead is mapped for these trails. The closest public access site is Canoe Launch, right on a shoreline trail (WDFW water access site data).
The dashed brown line on the lake map shows these trails. We include paths, footways and marked trails that OpenStreetMap doesn't mark as private, and leave out roads, sidewalks and snowmobile corridors. Mapped trails can still cross private land or close for the season, and not every trail is mapped, so follow posted signs.
Trails: © OpenStreetMap contributors, available under the Open Database License (ODbL). Map data as of Oct 9, 2026. Trail lengths count only the parts within about 90 m of the USGS NHD lake outline.
We found 10 campgrounds and RV parks within 15 miles of Lake Sacajawea, 2 of them within 5 miles. Distances are straight-line from the nearest point on the shoreline, so driving distance is longer.

Green tent icons on the lake map mark campgrounds near the shore, and the interactive map shows the closest 12. Amenities are listed only where a source records them; call or check the campground's website before you go, since seasons and rates change every year.

Live from the National Weather Service API for the lake's coordinates (46.1370, -122.9518). The nearest station may be several miles away. NWS forecast for Lake Sacajawea. No live water-temperature sensor is shown because we haven't found a public one for this lake.
Based on solunar theory, an estimate. Major periods (about 2 hours) center on when the moon is directly overhead or underfoot; minor periods (about 1 hour) center on moonrise and moonset. The 0–100 activity score rises during those periods and gets a boost near sunrise and sunset and around the new and full moon. Weather, water temperature and pressure often matter more. Sun and moon times are calculated in your browser from the lake's coordinates with standard astronomy formulas, shown in PT (America/Los_Angeles), and accurate to within a few minutes.
