About this file
This document is a presentation of five fiscal year 2026 (FY26) maintenance projects for aqueducts managed by the National Park Service's Chesapeake and Ohio Canal National Historical Park (CHOH). The projects involve targeted removal of accumulated woody debris and undesirable vegetation from five aqueduct structures along the canal's linear expanse: the Seneca Creek Aqueduct, Monocacy River Aqueduct, Catoctin Creek Aqueduct, Antietam Creek Aqueduct, Conococheague Creek Aqueduct, and Licking Creek Aqueduct. Each project includes photographic examples of existing conditions showing debris accumulation, plant growth, logjams, and obstructions that impede watercraft access, natural creek flow, and create potential structural concerns.
All five projects are listed with a cost status of "Pending Quote," indicating that formal pricing has not yet been established. The document provides structural profiles and technical drawings for each aqueduct, including measurements of upstream and downstream elevations recorded on specific dates in October and January. The work encompasses removal of fine debris, woody materials, and vegetation deposits from the aqueduct structures and surrounding areas. No specific response dates, contract vehicles, federal contract mechanisms, or set-asides are identified in this presentation document. The projects appear to be internal planning materials for the National Park Service outlining maintenance priorities and existing conditions rather than a formal solicitation or contracting vehicle.
