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
- 16 - Flooding reaches the lower bridge supports on Depot Road in T14 R16 WELS. Floodwaters threatening sporting camps along the Big Black River in T14 R15 WELS upstream of the Depot Stream confluence. Flooding similar to April 1987.
- 15 - Moderate flooding on properties upstream of the gage near the Quebec border.
- 13.5 - Minor lowland flooding occurs due to backwater in small streams and creeks. Additional, lowland flooding near the confluence of Depot Stream and upstream of the Depot Road to the Quebec border.
