From The Pueblo Chieftain (Chris Woodka):

The Resurrection Mining Co. has filed its plan in water court to permanently replace flows to the Arkansas River water from its Yak Tunnel reclamation plant.

According to a court filing in May, the company plans to dedicate 10 shares of Twin Lakes water to flow down Lake Creek to replace the water it is capturing and cleaning at the Yak Tunnel plant and surge pond about 1 mile southeast of Leadville.

The water court application formalizes an arrangement that has been in place since Resurrection took over operation of the Yak Tunnel from ASARCO after a bankruptcy filing in 2005.

ASARCO began operating the Yak Tunnel plant in 1989 following federal court decisions that required mining companies to intercept and treat drainage from mine tunnels. Twin Lakes shares were leased until the company bought its own shares in 1994.

Depletions amounted to 3-7.7 acre-feet (1 million- 2.5 million gallons) annually from 2006-13. Replacement for those flows were replaced under a substitute water supply plan, an agreement administered by the state Division of Water Resources.

The tunnel, like others in the area, originally was drilled to dewater mines and increase productivity. However, the drainage includes heavy metals that diminish water quality and endanger wildlife. The surge pond captures water that escapes from tunnels and allows the water treatment plan The court filing assures that an operating plan is in place, regardless of how much water is needed in any given year to replace depletion.
