American Rivers yesterday announced its annual list of Americaâ€™s Most Endangered RiversÂ®, naming California's San Joaquin River the Most Endangered River in the country. Outdated water management and excessive diversions, compounded by the current drought, have put the San Joaquin River at a breaking point.

American Rivers is calling on the California State Water Resources Control Board to increase river flows to protect water quality, fish, and recreation, and support sustainable agriculture as well as urge Congress to preserve agreements and laws designed to protect the San Joaquin River and communities it supports.

"On the San Joaquin and across the nation, communities can increase their ability to deal with drought now and in the future by protecting and restoring rivers and using water more efficiently," said Bob Irvin, President of American Rivers. "By prioritizing healthy rivers and sustainable water management, we can enjoy reliable clean water supplies, healthy fish and wildlife, recreation, and quality of life for generations to come."

For the second consecutive year, the report underscores the problems that arise for communities and the environment when we drain too much water out of rivers. Last year the Colorado River was #1 on the list because of outdated water management. This basin remains in the spotlight this year, with water diversion threats placing the Gila River and the rivers of the Upper Colorado Basin on the Most Endangered list.

The annual report is a list of rivers at a crossroads, where key decisions in the coming months will determine the rivers' fates. Over the years, the report has helped spur many successes including the removal of outdated dams, protection of rivers with Wild and Scenic designations, and prevention of harmful development and pollution.

This year's list includes:

#1 San Joaquin River

Threat: Outdated water management and excessive diversions impacting river health

#2 Upper Colorado River System

Threat: New trans-mountain water diversions impacting river health and recreation

#3 Middle Mississippi River

Threat: Outdated flood management impacting wildlife habitat and public safety

#4 Gila River

Threat: New water diversions impacting overall river health

#5 San Francisquito Creek

Threat: Dam impacting aquatic habitat and public safety

#6 South Fork Edisto River
