Laughing Jack Lagoon to be lowered for works

The Hydro Tasmania logo

The water level at Laughing Jack Lagoon will be gradually lowered from mid-November to prepare for works on the cofferdam outlet between January and March 2023. This project is part of our ongoing dam maintenance program which ensures the ongoing safe and efficient generation of renewable energy in Tasmania.

While the lagoon does typically fluctuate through the year, we are expecting the level will fall below the usual operating level, so we ask all visitors to take extra care. The Lagoon, campground and boat ramp will not be closed, however fishing access and conditions will be severely impacted due to:

  • Shallow water levels
  • Turbid water due to increased suspended sediment
  • Underwater objects may become exposed
  • Shore conditions may be softer or inaccessible

We will be working closely with Inland Fisheries Services to monitor conditions. As the lagoon is completely reliant on natural inflows, we do not expect the water levels to return as normal until July 2023.

We apologise for any inconvenience. For more information on fishing on our lakes, visit, and for alerts Alerts for visitors (
