... Today in Metro Denver weather history...
26-31 in 1995... a cool period with light morning showers and
moderate to heavy afternoon showers and thunderstorms
pushed rivers already swollen from mountain snow melt
over their banks causing minor flooding. Streams and
rivers such as the South Platte and Boulder Creek flooded
Meadowlands... bike paths... roads near streams... and other
low lying areas. No significant property damage was
reported and crop damage was unknown. Rainfall totaled
1.79 inches at the site of the former Stapleton
International Airport and only 1.51 inches at Denver
29-1 in 1894... heavy rain combined with snowmelt runoff caused
widespread flooding over the South Platte river basin.
Rainfall was heaviest in the foothills where 5 to 8
inches were measured over the 4 days. Heavy rainfall
west of Boulder flooded mining towns and damaged mining
properties. In the canyons above Boulder... railroads
and roads were washed out along with many bridges. The
floodwaters spread into central Boulder and covered a
wide area from University hill north to near Mapleton
hill to a maximum depth of 8 feet. Many houses were
swept away... and every bridge in Boulder was destroyed.
A few people... trapped in their homes by the floodwaters...
had to be rescued. However... the gradual rise of the flood
waters resulted in only one death. Boulder Creek spread to
a width of nearly one mile in The Pasture land to the east
of Boulder. Extensive flooding on Left Hand creek north
of Boulder washed away Railroad and wagon bridges. The
heavy cloudbursts caused flooding on Bear Creek... which
washed away bridges... Railroad tracks... and structures and
destroyed the canyon roadway. Morrison sustained the
heaviest flood damage on Bear Creek. In Denver... rainfall
totaled only 1.50 inches on the 30th and 31st... but the
heavy rainfall on upstream tributaries of the South Platte
river caused the river to rise as much as 10 feet above the
low water mark in the city... which caused some flooding of
pasture land downstream to a depth of 6 feet near Brighton.

Airport... where west winds gusted to 39 mph... received 1.51
inches of rain and hail... which forced the closure of the
runways for an hour. Hail stones to 3/4 inch in diameter
were measured at Buckley field. A funnel cloud was sighted

sections of Metro Denver. The strong winds uprooted a 25-
to 30-foot tree in the acres green subdivision of northern
Douglas County. The tree blocked a busy street for several
hours. A pilot reported hail as large as 1 1/2 inches in
diameter covering the ground near the north end of a runway

low lying areas and one person reported being trapped in his
