Trinidad Lake and Dam Master Plan Revision

Collapse All Expand All
 What is a Master Plan?

The Master Plan is the strategic land use management document that guides the comprehensive management and development of all project recreational, natural, and cultural resources throughout the life of the water resources project.

Revision of the Master Plan will not address in detail the technical operational aspects of the reservoir related to the water supply or flood risk management missions of the project.

 What a Master Plan is NOT

The Master Plan does not entail facility designs, daily project administration details or any technical discussion regarding flood risk management, water quality, water supply, shoreline management, water level management, hydropower, or navigation. Many of these topics are covered in the many other Operational Plans each lake develops separately from the master plan.

 Why Revise a Master Plan?

The current Master Plan was originally completed in October 1975 and is in need of revision to address changes in regional land use, population, outdoor recreation trends, and USACE management policy.

Key topics addressed in the revised Master Plan include:

  • revised land classifications,
  • new natural and recreational resource management objectives,
  • recreation facility needs, and
  • special topics such as invasive species management and threatened and endangered species habitat.

Public participation and feedback is critical to the successful revision of the Trinidad Lake Master Plan.
