Leaves and debris should never be placed in or near a storm drain, since rain events can cause debris to wash into the drain, clogging it and contributing to flooding. Additionally, chemicals should never be poured or rinsed into a storm drain. Remember "Drains to Lake". Whatever goes in our storm drains, eventually ends up in the lakes.

The City of Lake Saint Louis does not spray for mosquitoes. However, Saint Charles County does spray for mosquitoes.
Source control is highly recommended; mosquitoes breed well in stagnant pools of water. Make sure to remove all possible breeding sites such as flower pots, old tires, etc. Pools of water such as kiddie pools, garden ponds, and bird baths should be changed often to prevent mosquito larvae from becoming a predacious adult. Detention or retention ponds owned by the private property owners, including neighborhood associations are the responsibility of the property owners associations. Larvicide tablets are a good way to control the mosquito larvae.
