A deadline is looming for an agreement that could see dams removed from the Klamath River, while opponents call for the end of the settlement.

The Klamath Basin Restoration Agreement -- a series of proposals for water quality, flows and restoration contingent on the removal of four Klamath River Dams -- is set to expire Dec. 31 unless 42 stakeholders extend the agreement until 2014.

Stakeholders approved the agreement in 2010, and included the self-imposed deadline in hopes that Congress would legislate the proposal by the end of this year.

That has not happened, and while stakeholders appear to be largely in favor of extending the agreement, there are vocal opponents who are calling for the end of the KBRA.

The fight over the Klamath Basin goes back more than a decade, with the control of water flowing through four dams operated by PacifiCorp at the center of an intense debate.

The issue is largely split along the lines of fish advocates and tribes on the lower Klamath versus irrigators and farmers in the upper basin, each insisting that their livelihoods depended on more water. After years of negotiation, the KBRA was agreed upon by government agencies, tribes and other interest groups, but did not preclude a host of detractors.

Opponents at several meetings last week included members and representatives of the Hoopa Valley Tribe and several river consultants, who insisted that there are better ways to oversee the removal of dams, ensure the rights of tribes and protect fish and other wildlife in the basin.

The Humboldt County Board of Supervisors approved the amendment to extend the KBRA on Tuesday. As of press time, the board was one of six stakeholders who approved the extension.

On Wednesday, the Klamath Basin Coordinating Council -- the group of stakeholders that formed the KBRA and has the authority to amend it -- met at the Humboldt Bay Aquatic Center, where members heard a similar refrain of opposition to the KBRA.

Many opposed to the KBRA say that it's unnecessary because a process already stands in place for dam removal.

Since 2010, the Federal Energy Regulatory Commission's relicensing process for the river's four dams has been placed on hold by the state Water Resources Control Board -- at PacifiCorp's request.
