Environmental Resources
Section - publishes an Annual Hydrologic Data Report containing
data dating back as far as the late 1800s. New data are added
each year from 66 reporting (via radio telemetry) rain gages,
14 recording, non-reporting rain gages, 33 non-recording, cooperative
observer (maintained by volunteers) rain gages, and 36 reporting
water level stations.
These hydrologic data, coupled with
satellite and radar tracking of storms, are used for flood detection,
allowing maintenance crews to be assigned to potential problem
areas. The result is a better allocation of resources and enhanced
public safety. The data are also used for a variety of other municipal
purposes by the private sector.
