About this file
This document is a multi-page project plan for the National Park Service focused on removing woody debris and vegetation from 11 aqueducts along the Chesapeake and Ohio Canal Historic Park (CHOH) linear expanse. The project, scheduled for FY26, targets specific aqueducts including Tonoloway, Sideling Hill, Fifteenmile Creek, Town Creek, and Evitts Creek. Each aqueduct page includes historic or current photographs highlighting undesirable plant growth, architectural diagrams, and notes about potential environmental impacts such as creek flow obstruction and bank erosion risks.
The detailed documentation shows a systematic approach to vegetation management, with red-arrowed annotations indicating areas of woody debris, overgrowth, and potential structural interference. The project aims to execute a comprehensive, targetted removal of accumulated woody materials to preserve the structural integrity and historical features of these canal aqueducts. The images demonstrate varying stages of vegetation encroachment, from minor plant growth to significant logjams, underscoring the need for proactive maintenance along the canal's infrastructure.
