Contracted Aquatic Weed Control:

The Aquatic Weed Program involves the maintenance application of chemical herbicides to reduce vegetation growth in canals, ponds, lakes and ditches. The maintenance application is done to minimize drainage flow restrictions and assure design or natural conveyance capacity. Algae growth control is also covered. The Aquatic Weed Control Program includes County staff that are licensed in herbicide application and qualified contractors who are also licensed in herbicide use and application. Each selected contractor is chosen every two years by the County's Purchasing Department in a competitive bidding process.

Contracted Spray Site Locations: The County's geodatabase keeps track of the location of  ponds, lakes canals and drainage flow-ways that have been sprayed by contractors. These sprayed areas either the County owns or the County has legal control.

Controlling Alge
Spraying for Algae control
Controlling algae also helps improve water quality for water-dwelling fish and other critters by increasing oxygen demand by the algae and depleting the oxygen for fish and other marine life.

Contract spraying presently covers the two locations listed below.
