The 2020 Cameron Peak Fire, the largest in Colorado’s History, impacted over 200,000 acres of land, including vital watersheds close to population centers in Colorado, such as the towns of Estes Park and Loveland. Runoff and debris flows are a continuous hazard for approximately five years post-fire. This study takes a spatial approach to modeling runoff potential of the Big Thompson Subbasin Watershed, using curve number methodology to approximate runoff potential by combining land cover, soil data, slope, and burn severity. Field work indicated possible uncertainty in the model due to discrepancies with field sample soil hydro groups compared to soil dataset. Flow Accumulation model informs areas of highest risk within the curve number model output, with the aim to inform hazard mitigation and disaster management decision-makers how best to proactively lessen runoff risk.
