Our small group camped at the Lake Sonoma Marina campground and had a very spotty experience. There was no warning in their confirmation emails or website that there is NO WATER available at the campsite. Even the restrooms down at the marina state that the water from the taps is non-potable. You have to bring all of your water with you.

The portapotties were ok. Nothing great but nothing terrible.

The campground seems well maintained with the grass recently cut and poison oak only visible in small areas. The ground is not very flat so it was hard to find a great site for a tent.

The biggest problem was Saturday night when a large group came and took over two adjacent campsites. They brought lights and loud music with them and the lights and loud music stayed on until after midnight. This group finally turned off the speakers but continued shouting and screaming until 4 am. 

There is NO NOISE CONTROL and no attempt to enforce campground rules. There is no one patrolling the campsite and no one to call at midnight to request help to stop the noise. Don't bother staying here overnight. Come for the day to the enjoy the lake but go home and get a good night's sleep after.
