Lock 4 Canal Park, owned by the New York State Canal Corporation, is located in the Town of Schaghticoke, Rensselaer County, at Lock 4 of the Champlain division, where the Hoosic River enters the Hudson opposite Stillwater. Before the construction of the Lock in 1908-1912, three shale bluff islands existed at this confluence. The canal construction significantly altered the landscape, transforming two of these islands into part of the mainland. While the area is still highly scenic, the configuration and use of the land has changed markedly. Barge Canal records held by the New York State Archives are used to document these land changes and the canal construction process.

By the 1890s the canal system, dating from the opening of the famous Erie Canal in 1825, had become outdated and then Governor Theodore Roosevelt authorized a study, issued in 1900, which recommenced the construction of an entirely new modern canal system. This culminated in the construction and operation of the New York State Barge Canal System, which was completed in 1918. The Champlain Division of the Barge Canal begins in the Hudson River between Lansingburgh and Waterford and runs to Lake Champlain. It follows the entire western boundary of the Town of Schaghticoke. Champlain Division Locks 1, 2, 3 and 4 are located in this section of the Hudson.

The construction of Lock 4, opposite the Village of Stillwater, required major construction at the mouth of the Hoosic River, including two new dams, a major bridge and canal cut. Two islands became part of the mainland and old channels were filled in or became wetlands. The State acquired 91 acres of land, part of which later became Lock 4 Canal Park.

The park includes a picnic area, observation platform at the lock, a canoe launch, and short nature trails. The area is highly scenic, where shale bluffs overlook the Hoosic River raging over a series of rapids immediately before entering the Hudson. The park has been identified as a significant plant habitat, containing a wide diversity of species, including some state-listed rare plants.

The State Archives in Albany holds nearly 800 cubic feet of records relating to the Barge Canal development and construction. Reproducing and explaining maps, plans and photographs found in eight of these series of historic State records, archivist and R-TLC Director, Warren Broderick, brings the construction of this lock and section of canal to life.

Copies of this new publication are available for from the Rensselaer-Taconic Land Conservancy for $5.00 each, plus $2.00 sales tax and shipping per book.

These computer-generated maps, created in the R-TLC's Geographic
Information System (G.I.S.), shows the configuration of land and water
prior to Barge Canal construction as well as today, helping to explain the modern landscape.

One of a number of historical maps and other documents reproduced in
this booklet for the first time, this 1923 map shows the Barge Canal in
the vicinity of Lock 4.

Barge Canal records held by the New York State Archives contain many
construction photographs, specifications and diagrams, such as these detailed
drawings for canal powerhouse buildings.

Contract files contain detail estimates and final accounts of supplies
and materials used as well as description of some aspects of the actual construction.

Sketches of the entire lock and of detailed components are found in this vast
untapped resource of Barge Canal records held by the New York State Archives.

Albums contain a series construction photographs which document the progress of
the construction project from the first excavations to the project's completion.

Lock 4 Canal Park is open when the State Canal System is operative, usually between May 1 and November 30. Visit the park and hike the 1.5 mile nature trail along the bluff overlooking the junction of the Hoosic and Hudson Rivers. Bring a picnic lunch and watch boats "lock through" from an observation platform. Explore the passages between the mainland and islands by canoe, using the canoe launch at Stillwater just below the dam and hydroelectric plant. The scenery is most impressive in spring when water is running over the Hoosic River rapids, and in the fall when foliage color has arrived. Explore the gorge of Hoosic River when the water level is low in summer, and fish from the tip of the peninsula of the former Vandenburgh's Island, at the end of the nature trail.

To visit one the state's lesser-known but highly scenic state parks, enter from County Route 125, also known as Stillwater Bridge Road. Just east of the canal crossing the entrance road leads south to the lock and park. (NOTE: Do not take the road south of CR 125 immediately east of the Hudson River bridge and west of the canal bridge.) In spite of major changes to the natural landscape resulting from the canal's construction, time has healed the wounds created by the massive excavation shown in the ca. 1910 construction photos, and the area is a scenic and serene place again today.
