Adaptive Management Program Documents for Operations at Glen Canyon Dam

August 19, 2009
by John Weisheit


The documents of the Adaptive Management Program (AMP) for operations at Glen Canyon Dam (GCD) are provided here at On The Colorado as an alternative archive to the official web site maintained by the Bureau of Reclamation located here.

The program is charged by Congress to stop impairment of the biological and cultural resources of the Grand Canyon. The impairment is caused by hydropower operations at Glen Canyon Dam. These operations are to be modified by science and policy to improve national park values.

The main reason why we decided to provide this archive is the federal site does not contain a complete list of documents.

Though the AMP started formatively in 1995, the archive for AMWG (Adaptive Management Work Group) does not begin until 1997 and the TWG (Technical Work Group) archive begins in 1999.

Reclamation's site had a lot more broken links than it does today and has gradually improved the archive over time, so we appreciate these adjustments, but the missing years are...well...still missing.

They are not missing here at On The Colorado. However, you will notice that gaps remain, and when and if we acquire these documents, we will post them here.

Second, documents will be located on a single page in chronological order to eliminate unnecessary site surfing.

Third, sometimes the federal court system shuts down the web sites of the Department of Interior, so it is convenient to have this alternative site when that situation occurs.

An additional purpose is to demonstrate that some of the commitments this program is obligated to complete remain undone, or were completed after unreasonably long delays (or ironically fast-tracked). These include the annual report to Congress, integrating the Grand Canyon Protection Act (GCPA) into the Annual Operating Plan (AOP), completion of the temperature control device, reversing the persistent depletion of sediment, finalizing and implementing a programatic agreement with the tribes, implementing seasonally adjusted steady flows, finishing the Core Monitoring Plan, completing the socioeconomic analysis, and other matters.

You will also notice how unreasonable amounts of time are spent on meeting process rather than progress toward renewal of park resources, and that this obvious behavior is consistantly initiated by the protectors of hydropower revenues.
