The continuing drought has prompted the Cedar Rapids Water Department to dig a channel that will guide Cedar River water nearer a large well.
Cedar Rapids television station KCRG reports water from the 600-foot-long channel should recharge an area where one large collector well pumps water to a nearby water treatment plant.
City water currently comes from several shallow wells near the river that are recharged both by the river and rain. As the river level drops and the rainfall remains well below normal, groundwater supplies are dropping, too.
The U.S. Army Corps of Engineers gave permission earlier this month for the city to dig the channel.
