Environmental Surveillance

Rain Gauge
AMCD has rain gauges set up throughout the county to measure the amount of rainfall in the different areas of the county. This data allows the district to target areas of heavy rainfall and direct larviciding activities. Rain gauges are checked on Mondays, Wednesdays and Fridays.

Tidal Surveillance
AMCD currently operates two tidal gauges to monitor the tides in different areas of the county. This information allows AMCD to target control efforts of the saltwater mosquitoes. Tidal gauges are checked on Mondays, Wednesdays and Fridays.

Temperature, Wind and Daylight Surveillance
Mosquitoes growth rate and activity is controlled by temperature and hours of daylight. Growth rates and activity is highest when temperatures and humidity are high. Mosquito populations are also highest when daylight is longer than night. AMCD monitors all of these factors in determining larviciding and adulticiding operations.
