Stage‐Storage information was developed using Denver's
2008 topography. Stage‐Discharge curve was calculated
using as‐built plans and UD‐Detention Workbook.
Stage‐Storage‐Discharge curves were developed using
Denver's 2008 topography, storm drainage information.
This is a 100‐year capacity reservoir.
Stage‐Storage information was developed using Denver's
2008 topography. 100‐year capacity, outlet controlled by
18‐inch pipe.
