Document Description
The project is to replace the existing double penstock with a new single larger capacity penstock. The total project size is 21.1 acres. Construction will be conducted out of actively flowing waterways. The benefits of the project include maintaining hydropower electricity generation and preventing catastrophic loss of generating capacity. The existing penstock is over 100 years in age and has deteriorated to the point that it is near the end of its useful life. If the existing penstocks were to catastrophically fail, a large quantity of sediment could reach Battle Creek and significantly impact water quality.
