Historical flooding in the Uncompahgre Valley, described in
available news articles, has damaged or destroyed railroad track
and embankments, road and railroad bridges, roads, diversion
structures, and buildings and their contents. Inundation of
agricultural property has eroded farmlands; damaged and destroyed
crops and irrigation systems; reduced soil productivity due to
increased salinity; and deposited sand, silt, and debris on
cropland and pasture. Railroad and highway traffic has been
disrupted, public utilities damaged and destroyed, homes evacuated
for as long as several days, and cattle moved to higher ground to
protect them from the possibility of drowning.
