Lake Bridgeport Dam is owned and operated by the Tarrant Regional Water District (TRWD) and is located on the West Fork of the Trinity River in Wise County, approximately four miles west of Bridgeport, Texas.

FM Road 1658 was originally located on the crest of the dam and was reconstructed just upstream of the embankment crest when the dam was raised in 1971. The road is approximately 40 feet wide.
