Rainfall welcomed but not enough to help lake much

January 12, 2013

How much rain do we need to fill Lake Granbury? A bunch – and that’s just an estimate.

Brad Brunett, water services manager with the Brazos River Authority, said it’s difficult to put an exact number to the amount of rain needed.

“For example, a local 3-4 inch rain right around the city of Granbury might only result in a lake level rise of 6 inches or so. However, if there was a 3-4 inch rain over most of the watershed upstream of Lake Granbury, and if the soil was relatively saturated, the lake might fill completely,” he noted.

By Thursday afternoon the lake was up 6 inches, making it still 5 feet low.

Sheriff Roger Deeds said that he received no reports of roads closed due to flooding, and there didn’t seem to be any more vehicle crashes than usual.

“None of our low-water crossings caused any problems,” Deeds said, noting that a couple of calls came in asking to have deputies check out standing water on roadways. None proved deep enough to be hazardous.

“Our deputies went out and checked them, and they were not an issue,” the sheriff said.

One rainfall reading in Laguna Vista on Wednesday morning was 3.7 inches. A Lipan reading reached 3.25 inches, and about one-quarter inch was added.

Another Tolar location accumulated 3.5 inches for the two days, as did a reading at a Lipan residence.

A Cresson reading showed 3.71 total inches, and the total at the Hood County News for the two days was 3.27 inches.

Pecan Plantation readings included 2.8 total inches at one residence and 2.3 at another.


The rainfall may have messed up a few clean cars, but it probably would be next to impossible to find many people who seriously fussed about the much-needed wetness.

Some areas of the county reportedly had totals as high as 5 inches for the Tuesday and Wednesday event.

County Commissioner Steve Berry said he received a total of 4.25 inches for the two days combined where he lives, north of the bridge on Weatherford Highway north of Granbury. He said he talked to a couple of Tolar-area residents who measured between 4 and 4.5 inches in all.

“We’re very blessed to get this, at this time,” Berry said Thursday morning, referring to the lack of recent significant rainfall prior to Tuesday. “We laughed yesterday because stock show time was here on top of us.

“Obviously, one of our major things I deal with in my job is the economy of the lake. I don’t think they got the same rainfall (as Hood County did) around Possum Kingdom (Lake). It will help when we get to see the runoff. Hay farmers are relying now on their winter grass coming out. Hopefully it will help the farmers.”

The dry ground, coupled with the relatively slow pace of the rain, seemed to allow it to soak into the soil quickly.
