Cary owns and maintains a number of lakes and dams. These bodies of water serve multiple functions: flood protection, water quality improvement, recreation, wildlife habitat, and aesthetics.

Cary-owned lakes and ponds include the following:

• Symphony Lake
• Tryon Lake
• Carpenter Park Lake
• Twin Lakes
• Rogers Road Pond
• Pond at Diablo Disc Golf Course

Bond Lake, located within Cary’s Fred G. Bond Metro Park, was constructed by Wake County and the U.S. Department of Agriculture in 1972 as a flood-control structure, and is maintained by Wake County.

As with privately-owed lakes and ponds, these require regular maintenance to keep them in optimal condition. This includes routine monthly maintenance like mowing the dam faces and top; clearing trash and debris from the outlet structure; and monitoring for erosion along the shore of the lakes/ponds and repairing such erosion when found. Maintenance may also include clearing or repair of inlet pipes or repair of outlet structures. Larger-scale maintenance such as dredging is also required periodically.

In addition, depending on the size of the water body, amount of water impounded by the dam, and height of the dam itself, Federal and state regulations require annual inspection and certification of the dam by a licensed professional engineer.

Consistent and regular monitoring and maintenance are required to keep our lakes and ponds in good working order so they can continue to provide the functions and benefits to Cary and its citizens.

Citizens can assist in keeping our lakes and ponds healthy and beautiful. If you have any questions or concerns regarding Cary’s lakes and ponds, dial 311 anywhere in Cary, (919) 469-4000 outside Town limits, visit services.carync.gov or email 311@carync.gov.
