Colorado and New Mexico Regional Extreme Precipitation Study Completed

The Colorado and New Mexico dam safety programs have completed work on the
Regional Extreme Precipitation Study (CO-NM REPS). The REPS was a multi-year effort to update
rainfall estimates for spillway design at dams and other sensitive hydraulic infrastructure. New
probable maximum precipitation (PMP) estimates and previously unavailable risk-based Annual
Exceedance Probability/Precipitation Frequency (AEP/PF) estimates were developed for the study
region. Technical analysis of the extreme precipitation tools is complete with respect to rainfall
depths. Additional evaluation and guidance for the application of the new rainfall for hydrologic
analysis is forthcoming in 2019-2020 depending on funding availability. To view the documentation CLICK HERE…
