LOVELAND, Colo. -- The Bureau of Reclamation has finalized its Colorado-Big Thompson Project West Slope Collection Preliminary Alternatives Development Report that addresses concerns of water clarity at Colorado's Grand Lake. The report is available at

"The Department of the Interior is prioritizing efforts to improve water quality conditions in Grand Lake," said Assistant Secretary for Water and Science Anne Castle. "The Bureau of Reclamation, Interior's water management agency, is committed to protecting the aesthetic values of Grand Lake and maintaining a secure water supply for its customers. We recognize the problem and are working hard with state and local leaders to understand the causes and find appropriate solutions."

Grand Lake is part of the Colorado-Big Thompson Project's West Slope collection system, which diverts water under the Continental Divide to Colorado's East Slope and Front Range. A proposed state of Colorado water standard for the lake is scheduled to take effect in 2015. The Preliminary Alternatives Development Report is the first step toward improving water quality in Grand Lake in an effort to meet this state standard and improve this resource for its many uses. Four alternatives are considered in the report ranging from ceasing pumping during the summer season to building a bypass for project water to be delivered to the East Slope. The viability of each alternative is evaluated for a number of measures.

Reclamation continues to collaborate with water and power customers, stakeholders in and around Grand County, citizens groups around Grand Lake and Shadow Mountain Reservoir, recreation managers at affected water bodies and other local, state and federal agencies.

The final Alternatives Development Report has been provided directly to stakeholders and posted to Reclamation's website for the general public. Next steps include the Technical Review, which begins this fall and completes in fall 2013, and will examine the technical and financial feasibility of the alternatives presented in the Alternatives Development Report.
