Makes FY2023 supplemental appropriation of $17 million to DEP for grants for certain lake management activities.

S 418 allocates $17 million in supplemental funding to New Jersey's Department of Environmental Protection (DEP) for Fiscal Year 2023 to provide grants for lake management. The bill directly affects qualified entities - including lake commissions (like Greenwood Lake Commission and Lake Hopatcong Commission), local governments, and 501(c)(3) nonprofits - that manage publicly-accessible lakes. Key provisions require the DEP to prioritize grants for projects improving water quality, preventing harmful algal blooms, and increasing recreational access, with funds covering stormwater management and lake maintenance costs. This is a funding mechanism, not a policy change, directing existing resources toward specific lake conservation activities.
