Source reduction is the elimination of mosquito producing habitat by draining or filling of water holding situations. In South Walton, over 31, ( 44 Miles) major drainage ditches were dug by Mosquito Control to drain the land. These ditches are continually maintained by SWCMCD to ensure that they function properly. Maintenance to these ditches includes:

• mowing the banks, slopes and access roads.
• cleaning vegetation from the bottom of the ditches to ensure proper flow. 
• cleaning and repairs after heavy rain events.
