Hydrologic Outlook issued May 13 at 9:34AM MDT by NWS Billings MT

Effective: Wed May 13, 2026, 9:34 AM
Expires: Thu May 14, 2026, 3:00 PM

ESFBYZ Recent very warm temperatures has enhanced snowmelt in the mountains this week, resulting in significantly higher flows on area waterways. Flooding is not expected at this time due to marginal remaining snowpack in the middle elevations between 6000 and 8000 feet. Rivers that have seen increased flows include the Yellowstone, Shields, Boulder, Stillwater, and Clarks Fork. Some smaller streams flowing out of the mountains have also experienced rises. Looking ahead, cooler temperatures are in store for the end of the week. In fact, a seasonably cold weather system may bring freezing temperatures at high elevations and potential snowfall this weekend into early next week. The colder weather will slow or briefly halt the high elevation snow melt. Those with interests along foothills waterways should be prepared for higher water levels, and move property and livestock away from rivers, streams, and low lying areas. Runoff may fill culverts, ditches, and storm drains causing water to flow over foothills roadways potentially causing damage. Do not drive over flooded roadways, Turn Around Don't Drown. Recreationists in the mountains and foothills should be prepared for changing conditions and use extra caution when near waterways. Flows will be faster, and the water is very cold. Stay tuned to the forecast. Please report any flooding to local law enforcement and have them relay the report to the National Weather Service.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
