The Post Office opened on 1 January 1868 as Bridgewater-on-Loddon and was renamed Bridgewater around 1941.
Bridgewater has a new swimming pool and beach about two minutes walk from the Loddon Bridge Hotel, opposite the Post Office.
When reasonable water levels flow, the Mill Rapid downstream of the Calder Hwy bridge provides technical whitewater kayaking of Grade 3 standard featuring a short fast run. This should only be attempted by kayakers with an appropriate level of experience and training and equipped at the very least with spray covers, buoyancy vests and helmets. Access is usually via local roads on the west bank. If approaching on the water from upstream, beware of entering the flour mill race area on the right (east) bank. Upstream of the Calder Hwy bridge kayakers and canoeists will have a pleasant paddling experience but may have to share the river with swimmers, fishers, and waterskiers.
The town has an Australian Rules football team competing in the Loddon Valley Football League.
