Worries increase of San Pedro River's health as it runs dry

The Arizona Republic

The San Pedro River is running out of water at a closely watched measuring gauge near Tombstone, raising new alarms about the ailing river's health.

Flow at the Charleston Road bridge all but stopped Thursday and could dry up as early as today, two weeks earlier than in 2005, when hydrologists blamed drought and a late-arriving monsoon.

Conservation groups say excessive groundwater pumping has diverted much of the river's aquifer-fed flow, which helps fill the gap between winter runoff and summer rains.
