Coralville Lake Master Plan Revision

Coralville Lake is in the process of revising its Master Plan. The current plan has not been revised since 1977 and since that time many changes have occurred warranting the revision. These changes include things like federal policies, Corps regulations and guidance, and recreational use trends.

The revision process began in March 2015 and completion is anticipated by the end of 2018. Public input is important to the revision process and will be sought in a variety of ways including an online input form; written input via mail or email; public scoping open houses; and comments to draft or proposed plans. We want to know your vision for the future of Coralville Lake's recreation and natural resources. To provide input and/or be added to an email list to receive updates and notifications please visit the website link at the right of this screen or contact the Coralville Lake Project Office.

What is a Master Plan?

A Master Plan (MP) is a recreation, natural resource, and land-use management document. Per Chapter 3 of Engineering Regulation1130-2-550 and Engineering Pamphlet 1130-2-550 Corps policy, it is the "...document that conceptually establishes and guides the orderly development, administration, maintenance, preservation, enhancement, and management of natural, cultural, and recreational resources of a Corps’ water resource project." Despite what the name might suggest, it is not a plan for navigation (locks, dams and associated infrastructure for commercial barge traffic), flood risk management (such as levees in the PL84-99 Program), or water level management which are addressed in other guidance documents.

Additional information on the current approved plans, master planning process, Coralville Lake, or the recreation, environmental stewardship, or shoreline management sections can be found in the Additional Information links on the right side of this page.

Master Plan Public Input


We value input from the public and invite everyone to participate in the Master Plan revision process. We hosted two focus group meetings on Wednesday, Sept. 20 at 5 p.m. and 6 p.m. at the South Slope Community Center (980 North Front Street, North Liberty, Iowa) to facilitate discussions on balancing Coralville Lake's recreational opportunities and management of natural resources.
