Basin Update at Lake Gregory

 October 13, 2017
Basin Update

Basin projects are underway at Lake Gregory. To protect the lake water from sediment runoff, work is being done on the basins at the western and eastern tributaries leading to the lake. All work is confined to the west side of Lake Gregory Drive nearest to the library and the Houston Creek channel near San Moritz.

Trees and vegetation have been removed from the west basin that sits in front of the library and a concrete weir, a horizontal barrier that runs along the basin, will be added to retain sediment and reduce the need for future lake dredging. Once the west basin has been cleared, articulated block mats will be placed at the bottom to rest on the gravel base. These mats will allow access to the basin for future maintenance.

The basin work at the Houston Creek channel (that runs parallel to the San Moritz Lodge) will include fortifying the side slopes and creek bottom with rock protection to define the water course. Rock weirs will be established within the channel to capture and retain upstream sediment and keep it from entering the lake.

Both basin projects are on-schedule. The parking lot adjacent to the skate park will continue to be closed until project completion. Any audible construction equipment noise is being confined to workday hours of 6:30 a.m. to 4 p.m., Monday through Friday.
