An environmental coalition is making the third effort in 35 years to secure state management of groundwater for the beloved but hotly contested San Pedro River. Calling itself the San Pedro Alliance, the group asked the Arizona Department of Water Resources late Wednesday to create a state-run Active Management Area to oversee and protect groundwater resources in the Upper San Pedro River Basin. "What we want it to accomplish is that the basin will be at safe yield. That is defined as no more groundwater is being withdrawn than is being replaced annually," said Robin Silver, leader of the alliance and a founder of the Tucson-based Center for Biological Diversity.
