Just found this article, sorry if you have already used it but I don't have time to go through all the threads to look for it.

Reader reports and items which we have picked up off news groups are sounding pretty scary. Areas are being closed off, there are reports of dead
animals and even fish are reported dying off in large numbers. Against this background, the USGS says there is an increase in government monitoring,
such as a recent news release that says in part:
"In response to notably increased heat and steam
emissions in parts of Norris Geyser Basin, the
Yellowstone Volcano Observatory will deploy a
temporary network of seismographs, Global
Positioning System (GPS) receivers, and temperature
loggers. The temporary deployment is intended to
document chemical and physical signals that
accompany this increased activity, to identify the
underground locations of hydrothermal steam sources
and the relationship of the Norris geyser basin to the
background general seismicity, and crustal
deformation of the Yellowstone caldera. It may also
detect any precursory signals to geyser eruptions and
hydrothermal explosions.
A reader sends in this interesting compilation, which augments other reports we have had:
"fish are floating dead in the streams, and the lake is closed. A very
strong smell of H2SO4 (sulfur) People were leaving due to smell --- He also
mentioned that the Seismo sites had been shut down" and "there is a large
dead zone of animals and vegetation. Immediately outside this dead zone,
vegetation has stopped growing and animals are migrating out of the area.
New geysers and mud pots are springing up daily. You can physically see the
ground bulging up, not only at Yellowstone Lake, but in several places in
the park" enclosed are 2 brief reports on this matter.
