About the Coltsville Timeline

This guide is a timeline for the process of Coltsville petitioning to become part of the National Park Service. The major focus is on the federal legislation driving this process and the general history related to what is now called Coltsville. It is updated periodically. For histories of the Colt firearms: search our catalog; explore archives finding aids; look at the Colt Industries web site; go to the National Park site; and look at the "Further Research and Reading" and "Additional Resources" pages on this guide (updated periodically).

Public Law 113-291 includes a series of "Conditions for Establishment" that must be met before the park may be formally established. The National Park Service (NPS) is in the process of meeting the criteria.

Previously this research guide linked to most steps in the legislative process. As of April 2022, this guide will be streamlined by linking to the federal bill histories for the legislative process. Bill histories in include links to the relevant documents for a federal legislative history. Consult our research guide on federal legislative histories or  contact our reference librarians for additional information on the process. For detailed information about Coltsville becoming part of the National Park Service, please see our older archived guide:

September 17-21. The Colt Dike had been rebuilt and extended after the 1936 flood. Again sandbags (many filled with loam) were used to raise and reinforce the dike. Items on the first floor of factory were moved to the second floor. The flood topped at 35 feet. Source 28


Flood of 1936

March - Great Flood of 1936. March 11 - heavy rain. Vermont and New Hampshire sections of Connecticut River filled with melting snow. An ice jam formed where Farmington River joined the Connecticut River, which broke on Friday, March 13. The river hit a flood stage of 24 feet. By Sunday, it crested and began to recede. More heavy rain and melting snow brought the Connecticut River to 25 feet by Wednesday, March 18, and it continued to rise. People were evacuated from neighborhoods near the river. The dike was raised with sandbags, but the flood breached it on Thursday. The flood filled the first floor of the Colt factory and reached two feet on the second floor. Employee Robert Courtney is credited with saving the shipping ledgers. There was a wall of water when the dike gave way. It was Saturday morning before the river crested. At Colt, the water was recorded at 38.5 feet. Machines, engines, belts - they all needed to be dismantled, cleaned, dried, reassembled because the water and mud had reached the second floor. Three buildings were razed and replaced with modern ones. In Connecticut Valley, there was more destruction than Hurricane of 1938. Source 28, 37.
