Beaverton's own lake, held back by the city's own dam

Plenty of towns sit next to a lake. Beaverton sits next to one it owns. Ross Lake — about 294 acres of water right at the edge of town — exists because the Beaverton Dam holds back the Tobacco River, and that dam belongs to the City of Beaverton itself. Not the state, not the county, not a power company. The city.

The lake is shallow and friendly, maybe fifteen feet at its deepest, fed by the Cedar River and the braided branches of the Tobacco — north, middle, and south — that all gather here before the river spills over the dam and continues south. That makes Beaverton a genuine river crossroads: water arrives from several directions, pools into Ross Lake, and leaves as one river. Anglers work it for the usual warm-water mix, and a township park off M-18 gives the public a gravel launch, parking, a beach, and a picnic spot.

Owning your own dam is more burden than bragging right. It means the city, not some distant agency, is on the hook for the water level, the upkeep, and the long droughts — and Beaverton has lived through some. In the dry stretch of the late 1980s, low flows had water all but stopping below the dam, the kind of problem that lands squarely on whoever holds the deed.

It’s a different setup from the big reservoirs to the east — Secord, Smallwood, Wixom — which sit in a multi-county dam-rebuild district on the Tittabawassee. Ross Lake is its own smaller story, on a different river, under local control. When the town wants to talk about the lake, it’s talking about its own property — a stretch of the Tobacco River that Beaverton decided, a long time ago, to keep.
