The construction of the weir, according to the Council minutes, was designed by the Council's Civil Engineers Department which was a concrete and reinforced steel structure. The creation of this lake proved very popular with the community as many social functions were held as recorded in the newspapers. Those activities were swimming, canoeing, various games of sport and picnics. As part of this two small bathing boxes were erected as change rooms on the flat area close to the edge of the top of the bank. In 1931 a devastating flood in Enoggera Creek occurred under-mining the supporting earth bank at the west end of the concrete weir wall, reducing the water-retaining capacity of the wall and was not able to serve its design purpose – as well the bathing boxes were washed away and were not replaced. History has not recorded the outcome of the weir but it is believed within the community that the structure was dynamited and destroyed some time in the 1940s.
