YAPHANK - Environmental groups are calling on the Town of Brookhaven and Suffolk County to help clean up Yaphank lakes after they say the lakes have become filled with invasive plant species.

The groups say that the plants are making the lakes unusable for boaters and swimmers and also impeding the flow of water through the lakes.

The groups say they have been asking for funds to clean up the lakes since 2008 but that officials have done nothing to slow the spread of the invasive plants.
