LAKE SOMERVILLE - Folks in Somerville cooled off at the 'Dam' Lakefest, all for a good cause. That's d-a-m as in a structure, not the other word.
Among water fun activities at the lake, there was a Bar B Que contest, a car show, and plenty of live entertainment.
Proceeds from the event go to SAAMS House, the Somerville Police Department, and a tornado siren for Somerville.
A fireworks display wraps up the event Saturday night.
