Date Issued: January 28, 2020

Purpose: American Rivers seeks scope and fee proposals from design engineers for the removal of Chiques Roller Mill Dam.  

Project locationChiques Roller Mill Dam is located on Chiques Creek in Manheim, PA (Lancaster County). Coordinates for the site are: 40.10833333, -76.44333333. 

Background: American Rivers is requesting proposals for engineering design work to inform the removal of Chiques Roller Mill Dam (D36-198) on Chiques Creek in Manheim, PA. This stone masonry mill dam is approximately 10-foot high by 130-foot long and is no longer serving a useful purpose. The dam structure has been deemed compromised by PA DEP Dam Safety, and the owners are required to repair or remove it. They’ve chosen to remove it due to cost considerations. Chiques Roller Mill Dam is assigned a hazard classification of C-3, which means that a catastrophic dam failure would not result in loss of life but may impact critical infrastructure. 

Removal of Chiques Roller Mill Dam will open more than 13 river miles, reconnect a portion of the floodplain, and restore natural form and function to the stream. The partners for this project include American Rivers, PA Fish and Boat Commission, Natural Resources Conservation Service, Susquehanna River Basin Commission, and others.
