Lake Visitors/Users

NIEHS and EPA personnel, contractors, their families, and guests are welcome; however, in accordance with NIEHS Security Policy, government employees and on-site contractors must accompany their fishing parties. In addition,

  • Discovery Lake access may be limited depending on the COVID-19 Community Level for Durham County
  • All persons over 16 who fish must have in their possession a valid North Carolina inland fishing license. 
  • Guests and children must be accompanied at all times. 
  • Swimming is not allowed in Discovery Lake. 
  • Pets, smoking, and open fires are also not allowed. 

Fishing can occur along the entire lake shoreline. The Discovery Lake Map Boat Launch (92KB) is available for boat launch sites and fishing registration.  However, NIEHS maintains designated fishing areas that are regularly mowed to allow access to the shoreline.  These areas are located in the Memorial Gardens and adjacent to Building 101 D-module.
