1. The largest source of water is from the north fork of Mill Creek. I have found no mention in any Moab city report or U.S. Geological Survey report that identifies the north fork of Mill Creek as a recharge source for the Glen Canyon aquifer. This water is used by the Moab Irrigation Company in the summer but not in the winter
2. The city of Moab dumps millions of gallons of water into Mill Creek each winter that is produced in the spring near the golf course. The water is transported by pipe to the city’s tank above Powerhouse Dam. When the tank is full, the excess water is dumped into the creek.
3. The 3 cubic feet per second flow that comes down the south fork of Mill Creek recharges our aquifer and maintains one of the few riparian areas in our area that is used by thousands of tourists and locals. Moab city, USGS and the Manti La Sal National Forest all agree that the south fork of Mill Creek is a major recharge source for the Glen Canyon aquifer. Both the USGS and Moab city estimated the recharge at 650 acre-feet per year. This is enough water for over 1,000 homes in the city.
The water flowing out of the south fork of Mill Creek is a small portion of the water you see flowing through the city of Moab in the winter.
GWSSA’s proposal to reduce the flow in the south fork of Mill Creek is a transfer of culinary water to irrigation water for about 100 Ken’s Lake water users. The majority of GWSSA’s board members are Ken’s Lake users.
