Mahoning River Basin Water Managment Plan Update

The U.S. Army Corps of Engineers (the Corps), Pittsburgh District, is funded and tasked to look at the three reservoirs that operate in the Mahoning River Basin – Mosquito Creek Lake, Michael J. Kirwan Dam & Reservoir, and Berlin Lake - as well as the watershed as a whole to better understand the current needs, benefits and challenges within the region.

 

This undertaking will inform the Corps whether the operations of the reservoirs need to be changed to meet each reservoir’s authorized purposes while also investigating whether the authorization can be met while optimizing for other basin needs, opportunities and challenges. If it is determined an update is necessary, the Water Control Manual for each of the reservoirs will be updated

Public Input

The project team is currently working to scope the project and draft a public involvement plan to identify the most meaningful opportunities for the public to provide input into this process.

Progress Update

We've just started!

 

Starting in early 2019, Pittsburgh District began working on the Scope of Work for this effort. To gather feedback on the scope of work, collect information needed for the modeling, and answer questions, we met with members of the public and relevant agencies in June and July 2019. Starting in August 2019, we will begin using the information collected to start modeling. Once we have a clearer picture of the existing conditions in the watershed, we'll be reaching out to interested parties to share what we've learned and discuss next steps.

The Corps operates four reservoirs in the Beaver River Basin that reduce the risk of flooding and sustain water quality to downstream communities. The Corps has one dam on the Shenango River and three in the Mahoning River Basin that join in Lawrence County, Pennsylvania to form the Beaver River, which then flows into the upper Ohio River.

For this initiative, we are funded and tasked to look at the three reservoirs that operate in the Mahoning River Basin as well as the watershed as a whole to better understand the current needs, benefits and challenges within the region.
