Dear Honorable Members of Congress,

As New Mexico guides, outfitters, conservationists, and community advocates we rely on a healthy Rio Chama for our livelihood, personal enjoyment, and traditional ways of life. The 31 mile long Rio Chama Wild and Scenic River section below El Vado Dam is especially important to us. The area is filled with incredible biodiversity, contains great public access, and has the potential to be a world class destination and important economic driver creating jobs for local communities and our state’s burgeoning outdoor recreation economy. This stretch of the river is widely used by local communities for recreation, and the area has a rich Native American and Hispanic cultural history. However, for this area to reach its maximum potential, we must restore its ecological health by addressing the chronic turbidity of water released from El Vado Dam. Accordingly, we are asking for your help and support in addressing this critical issue.

The river flowing from El Vado Dam has a large impact on the Chama Valley, local communities and the region’s fish and wildlife. Due to the area’s geology and upstream land use practices above the dam, fine silt and clay sediments have accumulated at the dam at the level where water is released into the river below. The Bureau of Reclamation has operated the dam over the last 85 years. Over that time period, sediment loads released into the Rio Chama have averaged almost double the threshold that is considered ecologically deleterious to aquatic macroinvertebrate communities by the Environmental Protection Agency. Aquatic invertebrates are essential to the ecology and food web that supports both fish and wildlife in the Wild and Scenic River section of the Rio Chama.

To address this problem, the Chama Flows Project has proposed the installation of a gated inlet tower at El Vado Dam to allow the water to be released from the reservoir at a number of different elevations within the water column. The inlet tower would be an effective tool in controlling the current year-round turbidity in the river below, while still giving the Bureau of Reclamation the ability to flush sediment and maintain storage capacity of the reservoir. The inlet tower would allow sediment to get flushed a few times a year, consistent with natural events, rather than produce muddy water all year long. Due to the gated inlet’s variable intake elevation, water temperature can also be managed, further benefiting the river’s ecosystem and native species.

Further, El Vado Dam is currently leaking and costs about $300,000 per year to maintain. To address this distinct safety concern the Bureau of Reclamation has prepared a draft Corrective Action Plan detailed in the 52 page document titled “El Vado Dam – Safety of Dams Modification Project Daft Environmental Assessment.” The draft plan includes lowering the reservoir water level for about a year to allow for grouting cracks and installing a geomembrane (PVC cover) over the existing leaky faceplates. It also includes replacing the currently non-functional service spillway. Work is due to begin in May of 2022. The lowering of the reservoir pool and development of construction access to the toe of the dam for the proposed improvements provides a real opportunity to install a gated inlet tower. However, the current Corrective Action Plan does not include any attempts to correct the chronic turbidity problem of the Rio Chama.

There is a narrow window of opportunity before the Corrective Action Plan is finalized to include the installation of a gated inlet tower during the reservoir drawdown. The inlet tower would create a long-term, cost effective solution to the chronic turbidity problem and will have a positive impact on the area’s fishery, wildlife and ecosystem as well as on the local economy of the Chama Valley, all without affecting delivery of water to downstream users. We believe that the Bureau of Reclamation’s process represents a unique opportunity to fix a chronic problem and thus we are asking for your leadership and assistance in leveraging state and federal dollars to install an inlet tower on El Vado Dam. By making the installation of this tower a priority, you are supporting a cost-effective solution to a long-term problem as well as making a prudent investment that will have many benefits to New Mexico’s local communities, wildlife and outdoor recreation economy. Supporting this project directly promotes job growth when unemployment is at historic highs in an economically challenged region.

We are asking for your assistance to ensure we take advantage of this important opportunity.
