POCATELLO — A flood warning has been issued for a local river that will affect Bannock County, and the local street department has sandbags available for the community.

The National Weather Service in Pocatello issued a flood warning for the Portneuf River Thursday afternoon, and it is in effect until further notice. As of 10:45 a.m. Thursday, the flooding stage was at 7.9 feet. The river is expected to gradually rise to 10.9 feet on Saturday.

In a post on Facebook, NWS said, “Our first significant, long-duration warm-up has begun, with temperatures reaching the 70s and 80s for many locations starting this weekend. This will result in significant melting of our record snowpack.”

NWS said in the warning that the impacts on the Portneuf River include the following:

  • At 8.0 feet, water will encroach onto portions of the bike and walking trail next to the river in Sacajawea Park in Pocatello.
  • At 8.5 feet, sections of Sacajawea Park will be under water and the trail is usually closed at this level. Marsh Creek near Inkom may also be over its banks.
  • At 9.2 feet, flooding of low-lying agricultural land and pasture will occur in the Inkom and Blackrock area. Lowland flooding is likely along sections of the river between Portneuf Gap and the Cheyenne Avenue Bridge in Pocatello.
  • At 9.4 feet, water will encroach around sitting benches near the river at the Pacific Recycling Trailhead.

NWS warned if you are driving and spot flooding on roads, turn around and don’t drown.
