DOCK ADJUSTMENT WINCH
THAT RISES TO
The Patterson Dock Adjustment Winch, designed for a custom application at Lake Powell, is a great example of how our team can make operations safer, easier, and faster even when conditions fluctuate.
High line capacity to accommodate water level adjustment even where water levels vary near the dam
Extra shaft with hex attachment so it can be driven with a drill to quickly and easily adjust height of dock as the water level changes
Patterson's hallmark strength, reliability, and efficiency
OUR WINCHES MAKE
The lake level at Lake Powell fluctuates considerably depending on the seasonal snow runoff from the Rocky Mountains.*
Lake operators and visitors alike benefit from Patterson's innovation when it really counts, as water levels change.
* Upon completion of Glen Canyon Dam on September 13, 1963, the Colorado River began to back up, no longer being diverted through the tunnels. The newly flooded Glen Canyon formed Lake Powell. Eleven years elapsed before the lake filled to the 3,700 feet (1,100 m) level, on June 22, 1980. The lake level fluctuates considerably depending on the seasonal snow runoff from the Rocky Mountains. The all-time highest water level was reached on July 14, 1983, during one of the heaviest Colorado River floods in recorded history, in part influenced by a strong El Niño event. The lake rose to 3,708.34 feet (1,130.30 m) above sea level, with a water content of 25,757,086 acre feet (31.770898 km3). View references and learn more about Lake Powell here.
