Hidden Lake near Chama, NM

Riverbend Engineering completed a bathymetric survey of this high elevation lake. A Stage-Volume relationship was developed for the lake. Riverbend analyzed the hydrologic response of the watershed and calculated peak rates of runoff that would be expected in a 100-y event. Riverbend evaluated the hydraulic capacity of the existing spillway system, and made recommendations on how the capacity of the emergency spillway could be increased to meet current NM OSE standards.
