LADWP Crowley Lake Boat Inspections April 2025

Crowley Lake Boat Inspections Begin Thursday, April 24, 2025

To keep our waterways safe from the spread of invasive quagga mussels, all boats entering Crowley Lake will be inspected. Boats showing signs of contamination, or found to contain any water or debris that could harbor mussels will not be allowed to launch.

Boats that have tags from last season, do not need to be re-inspected as long as the original tag has not been broken or tampered with.

Boats that have been used on an infected water body within the last month, will be scrutinized heavily and may require decontamination. Currently, Crowley Lake is the only water body in Mono County that requires an inspection.
