| spillway_count = 11 The Wells project has ten generating units rated at a combined 855.2 megawatts. and the Confederated Tribes of the Colville Reservation.
Its reservoir is named Lake Pateros. Just below and adjacent is Carpenter Island boat launch and fish hatchery river access. Lake Pateros is not deep but a high volume of water moves through it. Thus, low-head, high-volume Kaplan turbine runners drive generation.
