Maybe, I'm not sure but a call or a website check may tell you. You can also make your own by using 3 stakes with some silt fence ziptied to it. Put one stake in center of ditch and one each side upstraem and attach silt fence. Straw bales shaped in a "V" also work.@R Q - do you know if Site One sells straw wattles for erosion control? I've got an asshat neighbor that redirected runoff and is making a hell of a mess of my stone lined river bed. I need to control the runoff and capture the silt before it fills in and buries all of my rock.
