June rainfall exceeds average within first 10 days

By Tracy Robillard, Public Affairs Specialist

June rainfall was a plentiful throughout the Savannah River Basin. Within the first 10 days of the month, all three sub-basins reached above-average rainfall levels compared to the June average.

The rainfall data we have only goes through June 24 due to technical issues on our water management website. We announced last week that the water management website is undergoing unanticipated maintenance and may be unavailable to the public for several weeks.

Here’s the rainfall data we have:

Through June 24, the Hartwell sub-basin recorded 6.74 inches of rain, topping the June average of 4.85 inches in just the first 10 days of the month. On June 10, rainfall at Hartwell totaled 5.41 inches.

Through June 24, the Thurmond sub-basin recorded 5.39 inches of rainfall, exceeding the month’s average of 3.81 inches. Like Hartwell, Thurmond also topped the month’s average within the first 10 days of June, with a recorded 3.87 inches on June 10.

The graphic below depicts June rainfall according to data from the National Weather Service. As you can see, the upper portion of the basin was in the red/orange category with 6 to 8 inches of rain for the month, while the middle portion near Thurmond Lake was in the pink category with 10 inches.

Now that we are entering the hotter season, the rainfall we receive yields much less results in reservoir levels. This is due to increased rates of evaporation and transpiration. Also, based on the greater water surface area at the higher elevations, such as in flood storage levels, it takes more water to realize comparable gains in lake levels.
