The ditch built to move water into Atlantic City, Wyoming for hydraulic mining, passed through miles of hard rock before snaking its way to Atlantic City, was finally completed in 1888. But, Granier’s dream would be foiled when it was found that the ditch had been built with too much slope and when the water rushed through it, many of the sluices were destroyed, spilling water and gold along the way. Small miners then rushed in and used the water for panning in the numerous gullies, many of whom were successful.
