Stream Run is a fishway construction workshop. Take migration orders for salmon, trout and shad, then run the full build: set survey stakes, hold concrete temperature while pouring the weir, tune orifice aperture and slope with live passage-efficiency readouts, dig the stilling pool, lock drifting cobbles into the bed, and count fish while you spot-check water quality. Flood surges can overtop the weir and halt the crew unless your cofferdam holds. Six depot upgrades all work on site, from precision pouring to a green works contract, and every purchase is kept forever. Settlements pay by passage efficiency times structural strength.
Build fishways on a living stream and guide salmon home.
