What happens at each level

  1. 9.00 ft

    Flooding of cultivated lands upstream of the Otowi gage will increase if water levels rise further. Fast flowing water could undermine the river banks.

  2. 13.00 ft

    Cultivated lands upriver through San Ildefonso and Santa Clara Pueblos are being inundated. Backwater flooding is occurring where creeks and arroyos join the Rio Grande. Debris in the fast flowing water could result in debris damming at nearby bridges causing local overflows. The flow in the river is approaching the flood flow of 1941 which was estimated at 22,500 cubic feet per second.

  3. 17.00 ft

    Flooding along the Rio Grande from above Cochiti Lake to Espanola exceeds the flood of 1920 and may exceed any flood level since 1740. Portions of San Ildefonso and Santa Clara Pueblos are inundated as are parts of Espanola.
