March 10, 2020 Beginning this spring, plant neighbors along CP&L Access Road may notice an increase in activity as we upgrade the existing Hyco Lake Auxiliary Spillway. Subject to permit approval, construction is expected to begin in May and be complete by early 2021. During this time, there will be occasional trucks hauling concrete and equipment near the spillway – our team will work to minimize impacts to traffic flow. 

This is the emergency spillway for the Hyco Lake dam, and it is accessed through gated Duke Energy property at the end of CP&L Access Road. This structure only sees flows during large precipitation events (a 5-inch rain event over 24 hours). The work is being completed to protect the dam from large precipitation events and is not creating a greater outflow capacity. The improvements are reinforcing the existing flow paths of water from Hyco Lake so the existing structure can continue to function as intended.
