are some new and continuing developments in Adaptive Management
Land: 1999 Beach Habitat Building Flow‹It¹s still possible that
a beach habitat building flow could happen sometime during the runoff
season, February to June (probably actually March to April because
of resource criteria). But, given the lack of snowfall in the Rockies
so far, reaching the ³hydrologic trigger² for making one happen
is looking unlikely. The trigger requires that Reclamation needs
to release 1.5 million acre feet or more for any month during the
runoff season. Any spike flow, as of now, would likely be less than
45,000 cfs and would last for about two days. The cap on a spike
flow reflects concern about loss of habitat for the endangered Kanab
Ambersnail at Vasey¹s Paradise. Scope of Adaptive Management ‹The
scope of what should be funded by the Adaptive Management Program
is presently under intense discussion. Upper Basin water and power
interests are doing all they can to squeeze the river ecosystem
into as small a box as possible. Why? They want to provide as little
funding and water as possible to preserve or enhance the river ecosystem.
We in the recreational community would be very concerned if the
scope of this program becomes excessive, but we are more deeply
concerned that it not receive the necessary funding and efforts
to adequately understand and predict any beneficial or detrimental
effects of Glen Canyon Dam on the river ecosystem in Grand Canyon.
Water temperature control device‹The idea from U.S. Fish and Wildlife
Service is that endangered native fishes in Grand Canyon will do
better if water temperatures are warmer in Grand Canyon, more like
the pre-dam era. A selective withdrawal device will be installed
on Glen Canyon Dam by Reclamation over the next two years. It will
cost about 15 million dollars, a real bargain compared to the original
proposal. An Environmental Assessment on this project should be
available soon. They expect to have it operational by 2002. There
is some concern that warming temperatures may also favor non-natives
that compete with or prey on natives. My appointment to these panels
is to represent the concerns of you 20,000 or so recreational river-runners
who float the Canyon each year. Please, keep me informed on your
thoughts and concerns. E-mail or write gcrg. I will do my best to
get back to you as my time allows. Otherwise, look for updates in
your copy of the bqr. Thanks.
