Substantial late spring rains impacting the region

When you think of the middle of June, you likely think of nice weather with people out enjoying the outdoors. However, the last few days have been unusually chilly and wet. Jon Wilson has more on the potential for flooding.

Hydrologist at the Rapid City National Weather Service, Melissa Smith says, "Creeks and streams are now starting to run really good across the area. We're seeing some higher stream flows, especially Rapid Creek, Spring Creek, Battle Creek, those areas."

On most days in the middle of June, you need ice water and perhaps some sunscreen to get through a day outside, but the last few days have been more like early spring or late fall.

Smith says, "This additional rainfall that we're watching move into the area, we could see some possible flooding concerns with just because everything's so saturated."

Heavy rains around the Black Hills have not caused widespread issues to this point, but with more moisture expected on already saturated ground, things are being monitored closely. A team from the U.S. Geological Survey is keeping track of flow in Rapid Creek.

USGS Hydrologic Technician, Joel Petersen says, "Typically today, we'd be 35-45 cubic feet per second. We're going to measure around 800-1000 cubic feet per second, so it's 10-20 times a normal flow."

When you include this past weekend through noon Monday, exactly two inches of rain has fallen in downtown Rapid City. That is over 10% of the average annual precipitation here in just three days. With the abundance of moisture, Smith expects spots near creeks and streams to be the most vulnerable.

Smith says, "With the ground already saturated, we're looking at a lot of the creeks and streams to become elevated, some possible flooding concerns are going to start entering into the mix with the already saturated conditions with this next bout of rain that we're looking at."
