The Lower La Chute Project and the Upper La Chute Hydroelectric Project (LIHI #185) 均位于纽约州埃塞克斯县提康德罗加村的拉舒特河上。拉舒特河从乔治湖流向尚普兰湖，长约 2.5 英里。

The Lower La Chute Project uses the 源头 formed by the Mill D 坝 of the Upper La Chute Project. The dam is the fourth in a series of six dams along the river and is located about 4,100 feet downstream of the Mill A dam (part of the Upper Project). The Lower Project uses flows from the Upper La Chute and from Trout Brook. The Lower La Chute project operates as 径流 and has a headpond with 2.3 acres of surface area with negligible storage. Flows from the D-Mill dam are conveyed by a 9-foot diameter 压力水管到发电站, located below the falls at Mill F dam. The dam creates a bypassed reach approximately 0.36 miles long. The powerhouse has a single turbine-generator unit rated at 3,600 kW. The Lower Project is accessible from Interstate 87, State Route 9N and local streets.

The Upper La Chute Project dictates operations of the Lower La Chute Project. The Upper La Chute Project operates in run-of-river mode and dictated by flow releases from Lake George which are regulated by New York State statute and the New York State Department of Environmental Conservation. A 30-cfs minimum flow is provided in the bypassed reach.

Waters within the project reach are designated as Class C(TS) in the bypassed reach, and Class C in the tailwater reach. Class C waters are best used for fishing. The application of (TS) indicates that the classifications are supportive of trout populations.

The La Chute River in the project vicinity supports a mix of warmwater and coldwater fish species. Of these, several migratory species are found at the project including blueback herring, alewife, American eel, lake sturgeon, landlocked Atlantic salmon, and sea lamprey. Atlantic salmon are maintained via stocking and American eel are similarly supported via stocking. Blueback herring, alewife, and sea lamprey are considered non-native or invasive and thus pose a threat to native species, especially trout and salmon. Passage is not desirable for these species as they could negatively impact native fish populations in Lake George. Downstream passage is provided by a weir at the Upper La Chute Mill D, and Mill F allows for a natural water fall which does not specifically provide formal downstream passage but rather an unobstructed flow downstream.

项目用地面积接近 500 英亩，涵盖上拉丘特和下拉丘特项目。项目附近的海岸线是落叶林和常绿林的混合体，有住宅和商业地产，还有观赏草。一些农田和湿地 are also found in the area. The 1992 Lake George 坝 Operating Guidelines for the Upper La Chute Hydroelectric Project provides specific provisions regarding the management of water levels in the Lake George watershed.

项目附近可能存在的受威胁或濒危物种包括印第安纳蝙蝠和北长耳蝙蝠。项目附近没有发现这两种物种的关键栖息地。其他列出的植物和鸟类物种被列为可能存在，尽管该项目不在这些物种可能存在的地区开展或影响这些物种。

Consultation with the State Historic Preservation Office concluded that project operations do not have an adverse impact on historical or cultural resources in the area. Additionally, the Lower powerhouse was constructed to keep with the historical nature of the Village of Ticonderoga, designed to blend in with the Village’s historical architecture.

Recreational resources at the project include a handicap accessible fishing platform at the Lower bypass along with a paved boat ramp with gravel parking located across the river. Since the FERC 豁免 does not require these facilities, they are provided voluntarily. The tailwater reach is home to Bicentennial Park which was built in cooperation with the project owner and includes a boat launch, walking trail, day use areas, and a handicap accessible fishing area. Public access is provided free of charge.
