Tai Tam Byewash Reservoir and Tai Tam Upper Reservoir are separated by a vehicular bridge. When full, the water from Tai Tam Upper Reservoir will pass through the bottom part of the bridge to Tai Tam Byewash Reservoir giving the appearance that the two reservoirs are jointly known as Tai Tam Reservoir ({{zh|t=大潭水塘|labels=no}}).

The reservoir can be accessed by Stage 6 of the Hong Kong Trail or by the Tai Tam Waterworks Heritage Trail.{{Cite web|url=https://www.hiking-hong-kong.com/hong-kong-trail-stage-6/|title=Hong Kong Trail Stage 6 - Hiking Hong Kong|work=Hiking Hong Kong|access-date=11 April 2021}}{{Cite web|url=https://www.hongkongextras.com/_tai-tam-waterworks_heritage_trail.html|title=TAI TAM WATERWORKS HERITAGE TRAIL - HONG KONG EXTRAS3|work=Hong Kong Extras|access-date=11 April 2021}}
