Following the wettest August on record, and a dry September, the Texas Water Development Board said Grayson County and much of Northeast Texas is experiencing “abnormally dry” conditions. The update came as a part of the board’s weekly water report, which was released Tuesday morning.

“Last week, we traded dry and drought conditions in most of South-Central Texas for dry and drought conditions in North and Northeast Texas,” Robert Mace, TWDB deputy executive water science and conservation administrator, said in the report. “In addition, we saw moderate drought increase in the lower Rio Grande Valley.”

In the latest report, Grayson, Fannin, Cooke and Collin counties were among the counties newly listed as experiencing abnormally dry conditions. This classification does not mean an area is experiencing a drought but continued dry weather can lead to drought classification.

This week’s report was released before storms rolled through the area Tuesday and early Wednesday and does not include that rainfall. Villanueva said the Sherman station reported 1.5 inches of rain from Tuesday’s storms, with NTRA reporting traces of rainfall.

Despite the dry conditions, Mace noted that the state reservoir storage remains above normal levels for this time of the year. On average, the reservoirs are 3.5 percent above the median of 80 percent full for this time of the year, he said.

By comparison, the pool elevation at Lake Texoma stood at 618.75 feet as of Wednesday afternoon. This puts the lake into its flood control pool, which was 6.37 percent full on Wednesday.

The report found that 4 percent of the state is currently in a state of drought, up from 3 percent a week ago. Following the arrival of Hurricane Harvey, the water board classified less than 1 percent of Texas as experiencing a drought.

The dry conditions in Texoma come following an abnormally dry September, where portions of the region saw less than one-tenth of an inch of rain throughout the month.

National Weather Service Meteorologist Villanueva said only 0.03 inches of rain was recorded at North Texas Regional Airport — Perrin Field. Similarly, a co-op weather station in Sherman received 0.02 inches for the entire month, she said. Normally, the station would receive about 3.59 inches, she said.

Villanueva said the region should remain mostly dry until early next week when a cold front brings increased chances on Monday.
