Because the Chenango Canal was never enlarged, it preserves the scale and specifications of the first generation of state canals, similar to the original Erie Canal, very little of which survives.","narrative":"A quarter-mile stretch of the Chenango Canal near Chenango Forks preserves the water-filled canal channel, its towpath, the remains of Lock 107, and a guard lock and dam on the Chenango River that diverted river water into the canal. Built between 1834 and 1836 by the State of New York, the canal ran 97 miles between Utica and Binghamton and used 114 locks. It struggled commercially because of difficult terrain, and the railroad of the 1860s cut the trip from four days to half a day. The state abandoned it in 1878. Since the canal was never enlarged like the Erie, this section keeps the dimensions and single-chamber lock design of the first generation of New York canals: a prism 42 feet wide at the top, 26 feet at the bottom, and four feet deep. The east lock wall is well preserved, and the towpath now serves as a hiking trail. It was recognized for its role in state transportation and early canal engineering.","period_of_significance":"1833-1878","architect_builder":null,"architectural_style":null,"criteria":["A","C"],"status_note":"Roughly a quarter mile of the canal is watered and state-owned within and beside Chenango Valley State Park; the north end of the lock is filled, some west wall stone is missing, and the towpath is maintained as a hiking trail.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:48.103028-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/10000359.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/10000359/605e448269-800.webp","url_1600":"https://nationalhistoricalregister.com/media/10000359/605e448269-1600.webp","licence":"CC BY-SA 3.0","author":"Stephen Schweitzer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lock_107.jpg\" rel=\"noopener\">Stephen Schweitzer</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Lock_107.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75312160","wikipedia":"https://en.wikipedia.org/wiki/Chenango_Canal_Prism_and_Lock_107","wikidata":"https://www.wikidata.org/wiki/Q14706224"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/broome-county/chenango-canal-prism-and-lock-107-10000359/"}
