Reservoirs return to their routines as summer arrives

The erratic spring cycle of high highs and low lows appears to have leveled off in June, as each of the sub-basins arrived much closer to its 67-year average for the first month of summer.

While Russell and Thurmond exceeded their averages with 113 percent and 107 percent (4.32 and 4.07 inches versus 3.83- and 3.81-inch averages, respectively), Hartwell fell just below the mark, receiving 4.5 inches — or 94 percent — of its 4.82-inch average for June.

According to the records generated by the Rainfall Chart2National Weather Service, which uses a spatial average of stage 3 doppler radar, the sub-basins gathered most of their “take” within the first 2 weeks of the month.

During this period, the rain fell steadily throughout the day, whereas for the rest of the month the sub-basins received their rain in the evening and early morning hours.

Looking into the rainfall crystal ball for July, which on average receives slightly more rain than June, it is likely the sub-basins will settle into a regular rhythm like this month, where they receive closer and closer to their average rainfall.

Historically (in the last decade), the first week of July has been mostly dry, so there’s more than a good chance for a beautiful weekend.

I’m no meteorologist, though, so the best I can offer is optimism for a sunny, fun-filled (and safe) Independence Day weekend.
