(2) a water intake structure at the dam;

(3) a 15,900-foot-long, 10-footdiameter unlined tunnel;

(4) a 60-foot by 150-foot powerhouse containing two turbine/generation units rated for a total of 25 megawatts;

(5) a 100-foot-long by 80-footwide open channel tailrace returning water to the West Branch Taiya River;
