Haven't got in touch with Karl yet...so hopefully I'm not stepping on anyone's toes.
Talked with the TPWD staff in charge of the scheduled planting on Monday June 6th. They said that with the high water on Conroe, they have postponed the workday until further notice. Best case scenario is to plant the water willow in 2 feet of water...and with today's levels, that would put the plants in everyone's yards...so they're going to wait.
