Mosquito Ditches

Many of the mosquito ditches that you see in this area have been dug and maintained by for mosquito control projects. They are functional in draining off water that might otherwise become stagnant and provide a breeding place for mosquitoes. The ditches also serve as a breeding place for smaller fish such as the mummichogs and silversides.

During the late summer, a yellow-green growth made up of diatoms and other marine algae appears along the ditches - it is an indication of the presence of excess nutrients.
