When Charlie Barrett passed on in 1946, his good friend and fellow rancher Jack Price bought the property from Charlie's widow and continued to develop the land. It so happened that Jack's property bordered on Crown Land that contained a muddy puddle called Dunalter Lake.

The story continues that in early 1950 a beaver dam across one end of Dunalter Lake caused the small lake to grow. Realizing that this water supply was perfect to use for irrigating Double D fields below, Jack was said to have covered the beaver dam with dirt, making a much better dam of his own.

Records at the District of Houston support the fact that a dam still exists at one end of the lake. Thus the local name "Irrigation Lake' and the reason why it is still classified as a "man-made" lake.

In 1970 the District of Houston applied to the Lands Branch to acquire the 44 acres around and including the lake for the purpose of developing a park and outdoor swimming area. In 1972, work began on the area and in May 1976 the Houston Lion's Club received a Land Improvement Grant of $1500 which they used to build a dock and outhouses. "Build it and they will come." And they did.
