Fossil Creek, a New Wild and Scenic River

Back to Spring 2009 Newsletter

Arizona has another Wild and Scenic River; Fossil Creek with it’s the travertine geological formations and crystal clear waters now shares the same protected designation as a segment of  the middle Verde River, the state’s only other Wild and Scenic River.

Approving Fossil Creek’s special designation was a detail in a massive piece of  legislation, the Omnibus Public Land Management Act, a package of  over 160 bills, that set aside more than 2 million acres of  newly protected wilderness in nine states. More than 3.3 million acres of  public lands in Arizona gained permanent protection. President Obama signed the law on March 30. 

Fossil Creek is an Arizona success story, an environmental rags-to-riches tale. Dammed early last century for power generation, Fossil Creek’s once quick-running water was a mere a trickle until the turn of  this century. In 1999, Arizona Public Service shut down the power plants, and restoration efforts commenced. 

The dam was lowered and diversions ceased in June 2005, restoring full flows to the creek. This is the first Arizona watercourse to have a major water retention structure retired.

In its heyday Fossil Creek was considered the fourth largest travertine system in the world. Fed by underground streams, it ran year-round almost 17 miles to the Verde River, its waters rich with calcium carbonate from the limestone aquifer below. 

Fossil Creek was one of  86 newly established Wild and Scenic Rivers with others located in California, Idaho, Massachusetts, Oregon, Utah, Vermont and Wyoming. Efforts are underway to gain support for a Wild and Scenic listing of  another Arizona River, the Blue River, a tributary to the San Francisco River.                                                                                             

Rivers or segment of  rivers are designated Wild and Scenic to protect special qualities including scenic, recreational, geologic, and fish and wildlife; they are not to be dammed or otherwise impeded to protect their free-flowing condition.

The recently passed law also provides other water-related provisions benefitting the state. Funding was authorized to support the federal government’s role in a comprehensive effort to preserve wildlife habitat along the lower Colorado River. The bill also authorized the Secretary of  the Interior to consider ways to supplement water supplies in the Sierra Vista Subwatershed to benefit Fort Huachuca and the San Pedro Riparian National Conservation Area.
