What drives Moses Lake’s History grade
On its age, its old homes and the National Register, Moses Lake is more historic than 4% of U.S. towns, #266 of 285 in Washington. Its National Register listings hold the grade up; its age pulls it down.
D−
HistoryA character grade: shown, never part of Moses Lake’s overall grade.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Moses Lake’s 0.0 sits below most of its state (27% of Washington towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to D. The pre-1940 share (±0.5 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1938 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Moses Lake’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Before the construction of Grand Coulee Dam on the Columbia River in 1941 and Moses Lake Army Air Base in 1942 the area was largely barren. Native Americans knew the area as Houaph, which meant willow. Chief Moses was leader of the Sinkiuse tribe from 1859 to 1899, and was forced to negotiate with white settlers who began to settle in the area in the 1880s. Under pressure from the government, Chief Moses traded the Columbia Basin land for a reservation that stretched from Lake Chelan north to the Canada–US border. The government later traded again for what is now the Colville Indian Reservation.
