 At the end of their first year of operation, the pumps had removed about 500,000 acre feet (620,000,000 m3) of water from the Great Salt Lake. The project was shut down in June 1989 since the level of the lake had dropped by nearly six feet (1.8 meters) since reaching its peak levels during June 1986 and March 1987. The Utah Division of Water Resources credits the project with "over one-third of that decline." In total, the pumps removed 2,730,000 acre feet (3.37 km3) of water while they operated.
