Lambert Creek Water Quality Improvement

Lambert Creek Water Quality Improvement

Project Challenge

Lambert Creek (old County Ditch 14) flows southwest from Goose Lake in White Bear Lake and ends in Vadnais Lake.  This project was the final phase to prepare for and install a 500-foot weir with 46 adjustable weir plates, excavate two retention ponds and install associated piping.  The intent of the project was to restore wetland function, provide greater flood protection and improve water quality.  Water that previous had drained all the way down Lambert Creek in three hours now may take three months to wind through the wetlands, reducing erosion and the deposition of unwanted nutrients in the St. Paul water supply.
