“We are expecting PK will come up about a foot,” she said. “At this point we can’t put an exact number on it because water is still coming in. There was a great deal of rain in West Texas below Lubbock. So, some of that will be coming our way and some will be caught by different reservoirs along the way.”
In comparison to PK, Lake Granbury has risen approximately 6 inches and Pierce said she does not think that it will rise much more. She added that the Brazos River, which flows into PK Lake, is deeper now as well.
“It’s come up quite a bit,” she said. “Basically what happens is you have a great deal of runoff during rain events that slowly tapers out as it goes downstream. So, what we’ve seen, for instance at the gauge just above Possum Kingdom Lake, is it was slow coming in; it kind of went up rather quickly and it’s going to be slow coming down. As water flows into the lake, that gauge measures how much is coming. It’s declining at this point, but it’s not completely finished.”
Pierce explained that the Brazos is considered “standing still” when moving at 100 cubic feet per second. Consequently, the river has been moving particularly fast since the rains started. The river peaked around Wednesday evening, hitting speeds as fast as 3,510 ft3ps. As of Thursday morning, the Brazos was running at 2,330 ft3ps. Pierce urged those looking to spend time in the river soon to use caution with regards to the current speed.
As welcome as the recent rain was, it would appear that Mineral Wells and the surrounding areas could still benefit from more. Both Pierce and Merz agreed the amount of rain so far would still probably not be enough to get the area out of drought status.
