On weekends & holidays throughout the summer, trained inspectors check boats, trailers and related equipment going into and out of the lake for any plants- and collecting those that are "suspected" of being an invasive.  Although the Cobbossee Watershed contains just 10 of the 156 staffed public boat launches in the state, our inspectors are routinely responsible for over 10% of the tates total yearly inspections; with 9,738 inspections done in the Cobbossee Watershed in 2017.  This shows the high density of activity in our area and the need for educating and assisting our residents and visitors to check their boat for plants when entering and leaving the water.


What Launches do we cover?
