National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 15 - Sections of soil-cement protectio overtopped and could fail, leading to widespread flooding.
- 13 - Silverbell Rd threatened between El Camino del Cerro and Ina Rd. Possible damage to bridge abutments along entire reach.
- 12 - Bank erosion likely outside soil cement protection, maily on left bank just downstream of Christopher Columbus Park and north of El Camino del Cerro. Inundation of gravel pits downstream towards the Rillito River begins.
