Forest Service Stewardship of Groundwater Resources on National Forest System Lands
The National Forests and Grasslands were established in large part to improve the management of lands that provide freshwater to the nation. The U.S. Forest Service is responsible for managing 193 million acres of public lands that are the source of about 14 percent of the nation’s overall freshwater supply and approximately one-fifth of the municipal supply. Groundwater plays a significant role in sustaining those water supplies. In recent years, attention to groundwater has become more pronounced due in part to droughts, and the public and the courts have increasingly expressed expectations that the Forest Service will address potential impacts to groundwater resources as part of its decision making.
To help meet these expectations, the Forest Service has been working on national direction to its decentralized field units on how to fulfill the agency’s stewardship responsibilities for groundwater, recognizing state and tribal authorities for water allocation and water quality protection. The goal is to make Forest Service decision making more consistent, credible, predictable, and transparent and help the agency be a better partner with states, tribes, and others when decisions are being made about uses of National Forests and Grasslands that may affect groundwater.
In May 2014, the Forest Service published for public comment and initiated tribal consultation on a proposed directive (internal instructions to agency offices in 44 states and territories) on groundwater resource management, Forest Service Manual 2560. The Forest Service received over 250 comment submittals containing more than 2500 individual comments. In response to the concerns raised about the proposed directive, the Forest Service stopped the directives process in December 2014 and is proceeding with additional engagement with states and tribes. The agency wants to make sure it clearly understands their concerns and can appropriately address them before proceeding with public comment and tribal consultation on a new directive.
