Structure S-151 is located in Water Conservation Area (WCA) 3A at the intersection of the Miami Canal (C-304) and L-67A Canal (Figure 1), which is approximately 4 miles southwest of the S-9 Pump Station. The S-151 Structure consists of six (6), 84-inch, corrugated metal pipe culverts, located at the point where L-67A crosses the Miami Canal, about 20 miles west of Miami. Control is affected by six manually operated sliding gates mounted on a steel frame erected on the upstream side of the structure. The structure allows the release of water from WCA 3A to meet water needs for South Miami-Dade County along the Miami Canal C-6, C-7 and C-8 during the dry season. It can also be used to discharge excess water to tide from WCA 3A and 3B, when capacity is available in the Miami Canal.
