As the last of the four projects along Maine’s Penobscot River, this 100 to 200 foot-wide bypass channel around the Howland Dam was constructed in 2015, improving access to nearly 1,000 miles of historic habitat for 11 species of native sea-run fish while maintaining or increasing energy generation on Maine’s Penobscot River system. The bypass channel design elements included providing a high level of service, as well as stability and function over flows from 250 cfs to nearly 12,000 cfs. Kleinschmidt and Inter-Fluve collaborated with the Penobscot Trust on the design of this project. The design included consideration of landscape design and public access components, and renderings to depict the proposed condition for project stakeholders.
The project won the 2017 ACEC Maine Honor Award for Water Resources.
