From the City web site: “Jonestown has existed as a populated rural community since it was originally settled by the Jones brothers, Emmett and Warren in the late 1930’s. Around 1940, Warren built the first commercial structure in what is now Jonestown. When Mansfield Dam was increased in height, and Lake Travis was filled, the development of Jonestown as a lake resort became possible. Begun at first as a haven for weekend fishermen and boaters, more and more people built their permanent residence here and commuted to work in Austin. A few fishing cabins still remain, but large, new homes are being built on estate lots in gated communities, many with lake-front or lake views.” There are some properties that allow horses in the Jonestown area.
