DeForrest A. Mattison, a park forest supervisor and unpaid observer for the U.S. Weather Bureau, set up the park's first weather station in September 1924. First located in the Quaker area, the station was moved to this site in 1929. In subsequent years, the park rangers, and most recently the park police, kept daily records of maximum and minimum temperatures and rainfall.
The wide, funnel-shaped top of the rain gauge collects precipitation. A smaller diameter inner tube concentrates precipitation to make it easier to measure. Two inches of rain translates as 0.2 in. of precipitation on the measuring scale.
Special thermometers record the maximum and minimum temperatures.
Equipment currently in use includes (from left to right) a rain gauge, max/min thermometers, and a barometer.
A July 8, 1998, microburst destroyed trees near Red Jacket trailhead. Note the lightning burn in the photograph at right.
Two severe windstorms, a tornado, and a microburst, occurred in the park during the 1990s. The August 28, 1990, tornado damaged the Cain Hollow Campground, destroyed 200 acres of forest on Mt. Onondaga, and flattened eight smaller stands of trees across the park's southern side. The July 1998 microburst uprooted or snapped many trees on Red House Lake dam, at the beach, and behind the Administration building.
A June 14, 1994, flash flood extensively damaged park roads, bridges, and recreation areas. Debris from numerous beaver ponds floated in Red House Lake.
A second flash flood in January 1996 damaged the boathouse so badly that it had to be moved to a new site.
