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
- 35000 - Moderate Flood Flow - This discharge (flow) level has a roughly 10 percent chance of being reached in any given year. Flooding near vulnerable locations along the active river channel may become more significant and widespread. This level was reached during the flooding in 2012.
- 30000 - Minor Flood Flow - This discharge (flow) level has a roughly 20 percent chance of being reached in any given year. Additional vulnerable locations near the active river channel may experience some flooding at this level west of the Old Glenn Highway in the Butte and near Sutton from Milepost 64 to 66. Residents are advised that for the past several years at both of these locations, the main channel of the river has been shifting closer to the bank.
- 15000 - Action Flow - This discharge (flow) level represents the higher end of the typical summertime range, and will likely be reached at least once nearly every year. Localized minor out-of-bank flooding may start to occur along parts of the Glenn highway, especially east of Sutton from milepost 64 to 66.
