Protect Rio Chama

A Canadian mining company wants to explore for uranium in the headwaters of the Rio Chama, threatening the water source for acequia farmers, land grants, tribal nations, ranchers, and thousands of families across northern New Mexico.

The Issue

Gamma Resources Ltd., a Vancouver-based company with no production history and a $22 million accumulated deficit, has proposed exploratory uranium drilling within the Carson National Forest near Canjilón, New Mexico. This is not a small survey, it is the opening move toward full uranium extraction from the headwaters of the Rio Chama.

The Rio Chama feeds acequia systems, traditional Hispano communities, tribal communities, shallow domestic wells, and agricultural operations throughout northern New Mexico. Uranium contamination, once it enters an aquifer, may be impossible to fully remediate.

local opposition is growing

The Upper Chama Soil and Water Conservation District passed a resolution on April 21 demanding a full Environmental Impact Statement, a drilling moratorium, tribal consultation, and water quality testing, followed two days later by the Rio Arriba County Commission’s unanimous vote opposing uranium exploration. Both resolutions work within federal law, insisting that the 1872 Mining Act’s right to mine does not excuse faithful application of NEPA, the Clean Water Act, and Forest Service regulations.

Local supporters gather to have their voice heard at the April 23rd Rio Arriba County Commission meeting.

“Energy security built on the contamination of tribal water systems and century-old acequia infrastructure is not security — it is the transfer of risk from a foreign company’s shareholders to New Mexico’s rural communities.”

The Rio Chama Basin & Outdoor Recreation

The Rio Chama Basin is both a treasured landscape and an economic cornerstone for northern New Mexico, drawing rafters, anglers, and hunters to its waters and national forest lands while sustaining generations of local families. This outdoor recreation economy—guides, outfitters, and small businesses—depends entirely on clean water. Uranium contamination would harm drinking water and agriculture, and devastate the tourism and fishing industries that provide livelihoods, making water quality a fundamental economic issue as much as a public health one.
