Date: Thu, 11 May 2023 20:01:46 EDT

Summary: Moderate flooding across Colorado’s Front Range caused by heavy rainfall over the past 24 hours.

Between 2 and 4 inches of rain has fallen on Colorado’s Front Range over the past 24 hours and has caused moderate flooding south from the Denver Metro, through Colorado Springs, to Pueblo. Twenty-seven gages are currently at an all-time high for this day of the year. Flow measurements are being made by six teams out of the Lakewood Field Office and four teams out of the Southeastern Colorado Field Office. Water quality storm samples are being collected by teams out of each office. Primary areas of flooding are the southern Denver Metro area, Monument Creek north of Colorado Springs, and Fountain Creek from Colorado Springs to Pueblo. One measurement made in Denver today on Cherry Creek will be the highest direct measurement made at this site on record. Low to moderate intensity rainfall is forecast to continue through this evening.

Tomorrow, crews from the Lakewood and Southeastern Colorado Offices will be conducting recessional measurements, verifying high-water marks, flagging reaches for indirect measurements, and repairing gages that were damaged during the event.
