Yes, you can pull the weeds growing under your dock. And, no, you don’t have to call the BRA. From the Brazos River Authority office in Waco, spokeswoman Judi Pierce said it is not necessary to notify the BRA regarding weed and brush removal on Lake Granbury. Some have lowered their lawn mowers onto the area once traversed by boat. In rocky areas, the string-trimmer has been used by others. Pierce notes that Rodeo herbicide is safe to spray on weeds in the lake bed, and will be safe when there’s run off into the lake, or when water comes back.
