The National Weather Service uses the data, along with other information, to issue flash-flood warnings and weather advisories. Data is collected at 54 gauge sites from 38 automatic rain gauges, 35 water-level gauges and five automatic weather stations. The stations automatically report data to computer base stations. If gauges exceed a set level, emergency management and utility personnel are notified.

Larimer County residents may sign up for emergency notifications on cell phones, business phones, via text messages and e-mails in addition to traditional landline phones. Learn more at leta911.org.
