tOutput not calculable until water available is known.
In 1880 the total water used for hydraulic mining on Bear River was 1,117,082 M.I.D. which was estimated to have
duty of 3, giving an annual yardage of 3,351,246. There was a large volume of top gravel in this, the yield from which
would be low.
