"located along the valley margins (Gates and others, 1984). In terms of quantity,
the main sources of recharge are seepage from streams, infiltration from irrigation

valley-fill aquifer in the Morgan Valley area is by seepage to the Weber River and
East Canyon Creek; transpiration by phreatophytes, crops, and pasture
vegetation; discharge from wells and s ..."
