Lake Whetstone Dam Toe Drain Project Update

As outlined on the County website: “During DEP’s routine maintenance inspection of the Lake Whetstone dam and outfall it was discovered that the toe drain is corroded and in need of replacement. The purpose of the toe drain is to collect water seepage in the earthen dam and safely convey it to the pond outfall.  Toe drains perform an important function in maintaining a safe and secure dam. If not replaced the toe drain pipe would eventually collapse and fail to convey water seepage safely through the dam. The repair work will involve abandonment of the existing toe drain pipe, excavating a new trench and placement of two new 8” slotted, double walled, corrugated HDPE (plastic) pipes that terminate at the concrete outfall wall.”
