History of Lewisville Lake
Before the lake:Denton County was a rural farming community in the early 1900's. What wasn't in farmland was either Crosstimbers post oak forests or prairies.
Lake Dallas:The City of Dallas constructed the original lake, Lake Dallas, in the 1920's for water supply. The Garza Dam on the Elm Fork of the Trinity River was completed in 1927 and water storage began in 1928, creating the lake. The orignial dam was 10,890 feet long with a 567-feet long service spillway. Normal pool elevation was 515 feet above msl (mean sea level).
The lake today:
The 28,980-acre lake serves to fulfill a variety of local and regional needs. The primary purposes of the lake are flood control and water conservation. Associated purposes include fish and wildlife management and recreation. The operation of Lewisville Lake was modified in 1988 as part of the construction of Ray Roberts Lake, upstream of Lewisville Lake, resulting in a permanent increase of the conservation pool elevation from 515 feet msl to the current 522 feet msl.
