Volunteers needed

You don’t need to live on the lake to be involved in the lake! We are looking for a big group of volunteers to make the Lake Hopatcong Block Party an amazing kick off to the summer season on the lake.

Volunteer information

This is a FUN day, and you get to work with our fabulous volunteer coordinator, Judy Caruso (that’s Judy below in the grey sweatshirt and purple hat)!

New this year…

Visitors are eligible to win great prizes, as they travel through the Block Party on a “Passport Adventure”.  More information coming soon!

We hope you will participate in celebrating Lake Hopatcong and the communities surrounding it!
