Low flows for endangered species are anything but popular

DURANGO, Colo. -- Very few of the millions of anglers that regularly recreate
across the West know what a squawfish looks like, nor do many of them seem to
care. All they know is that study efforts by the Bureau of Reclamation to
reduce stream flows during the winter to save more current for endangered
species in the spring months threaten to wreak havoc with existing trout
fisheries. For two weeks next month, the BuRec plans to reduce by half the
normal current of the San Juan River that flows from Colorado into New
Mexico.

Originally, the Bureau proposed to drop the flow of the San Juan below Navajo
Dam in northwestern New Mexico to 250 cubic feet per second (cfs) for four
months from November through next February. Reducing the flow of the river
during the winter is part of an interagency experiment to determine the
effects on endangered fish species, primarily squawfish that live farther
downstream than the more popular trout. It is generally believed that holding
more water behind upstream dams in the winter and releasing more in the
spring and summer will benefit squawfish. However, anglers and others are
concerned that reducing the flow during the winter months might dry up some
of the riverbed and would create undue stress on trout.

After a series of public hearings where considerable opposition was voiced
against the low-flow experiment, BuRec has amended its plan to go with a
two-week, 250 cfs flow study, which has tentatively been scheduled for the
first half of January. In recent years, winter flows on the tailwater section
of the San Juan haven't dropped below 500 cfs.

The bureaucratic tinkering with the flow of the San Juan River even has some
state officials saying some discouraging words. "A lot of this stuff is
nonsense," a New Mexico Game and Fish Department biologist was quoted as
saying. "It's just a ploy by the water developers to get what they want."
