Difference between revisions of "2017 Water Quality PEP"

• Shift emphasis from Lake Powell to downstream over the next few years.
• Employ water quality-ecosystem models in Lake Powell and the Colorado River to link Glen Canyon Dam (GCD) operations and physical/chemical/ecosystem responses in a timely manner using the best information available.
• Work with other programs in the Grand Canyon Monitoring and Research Center (GCMRC) Biological Resources Program in the integration of results to allow decision-making by the Technical Working Group (TWG) and the Adaptive Management Working Group (AMWG) by linking operations of GCD to various ecosystem responses.
• Develop a “proactive” long-range water quality monitoring strategy to evaluate current and future water management actions at Glen Canyon Dam.
• GCMRC should work with the TWG to improve the Management Objectives/ Information Needs (MO/INs) process.
• Lake Powell forebay station should be changed to the White Category.
• It is imperative that the GCMRC provide critical information in a timely manner to allow cost-effective and environmentally effective decisions for the Adaptive Management Program (AMP).
