This includes Cottage Grove and Dorena Lakes. Master Plans (MP) are required for most civil works projects and serve as the strategic land use management document that guides management and development of all project recreation, natural and cultural resources throughout the life of the project. Items covered in an MP include, but are not limited to, water, fish and wildlife, vegetation, cultural, aesthetics, interpretation/education, and recreation. USACE managed lands and waters (including those leased to others and easements) are all considered.  The goals of the Master Plan and Integrated Environmental Assessment include:

• Identify the best management practices to respond to regional needs, resource capabilities and sustainability, and expressed public interests consistent with authorized project purposes.
• Protect and manage project natural and cultural resources through sustainable environmental stewardship programs.
• Identify outdoor recreation opportunities that support project purposes and public demands created by the project itself while sustaining project natural resources.
• Recognize the particular qualities, characteristics, and potentials of the project.
• Provide consistency and compatibility with national objectives and other state and regional goals and programs.
