and Beluga on the west shore of upper Cook Inlet. The waterway and its tributaries are vital to the subsistence lifestyles of local residents whose villages are not connected to Alaska's road system. Though marked on some maps as "highways," the only roads in the area are primitive structures left behind from past oil and gas exploration and logging activities. The piedmont lowlands are covered in birch, poplar, and spruce forests and muskeg. Toward the northwest, the topography rises to a treeless plateau that extends to the Alaska Range. The local climate varies between maritime and continental, with annual rainfall measuring about 100 cm in the Chuitna River basin.

Development

The area through which the Chuitna and its tributaries flow is rich in coal and is known as the Beluga Coal Fields. PacRim Coal LP, a Delaware Corporation, holds a lease on of land within the coal fields. The corporation is pursuing state and federal permits for a massive surface strip mine called the
Chuitna Coal Project The Chuitna Coal Project was a proposed coal strip mine that, if granted state and federal permits, would have been built about southwest of Anchorage, Alaska, in an area known as the Beluga Coal Fields near the Chuitna River and the small commu ...
. If granted those permits, PacRim proposes to excavate as much as 1 billion metric tons of coal from the lease territory over several decades. PacRim officials have said the mine would create 300 to 350 jobs and a tax revenue stream to local and state government coffers.Status Update Chuitna Coal Project (Produced by former PacRim contractor; DRven Corp.

Conservation

Critics say the mine would devastate as much as of wildlife habitat and destroy vital tributaries to the Chuitna River, including some of salmon spawning and rearing sites. Permitting the mine would be unprecedented, marking the first time Alaska had ever permitted mining through an active salmon stream.Inletkeeper Winter 2008-2009 Newsletter
