The Hailesboro No. 4 Project (FERC No. 6058) is located on the Oswegatchie River in St. Lawrence County, New York. The 132-mile long Oswegatchie River is located in the St. Lawrence River watershed. The 源头 奥斯威戈奇河位于阿迪朗达克山脉，河流大致向西流，然后向北流，最后流入纽约州奥格登斯堡的圣劳伦斯河。

The project is located at river mile (RM) 67.7 and is the 7th 坝 位于河口上游，是三个相关项目中最下游的一个，其中还包括 海尔斯伯勒 3 号 (LIHI #197) 和 海尔斯伯勒 6 号 (LIHI #199)。该河在黑尔斯伯勒 6 号（岛屿支流）上游分为三支，并在黑尔斯伯勒 3 号下游的项目之间重新汇合。

The project was originally constructed in 1936 and operates under a license issued by the Federal Energy Regulatory Commission on October 30, 2002 which was amended on September 19, 2012, and expires December 31, 2032.

该项目包括：

  • a concrete gravity-type dam comprised of the 105-foot-long, 14-foot-high dam #1 surmounted by a 2-foot-high pneumatic 顶门 and the 58-foot-long, 5-foot-high dam #2 surmounted by 2-foot-high wooden 闪光板;
  • a reservoir with a surface area of 2 acres and a gross storage volume of 20 acre-feet at normal water surface elevation 461 ft 胃肠疾病 that creates a 0.4-mile-long bypassed reach;
  • a gated intake structure with steel trashracks which have 1.75-inch clear spacing;
  • a 170-foot-long concrete-lined forebay 运河 with a sluice gate;
  • a reinforced concrete and concrete masonry 发电站 containing two horizontally mounted, double runner, Francis-type turbine units; one 900-kW generating unit and one 1,000-kW generating unit for a total installed capacity of 1,900 kW;
  • a 2.4/23-kV 变电站, a 50-foot-long, 23-kV transmission line and appurtenant facilities; and
  • a 73-foot-long by 3-foot-high concrete gravity 导流 dam (Island Branch Weir), topped with 1-foot-high wooden flashboards, located at the entrance of the Island Branch of the Oswegatchie River.

该项目在 径流 流入量接近流出量且蓄水面高程波动最小的模式。 扣押 drawdowns are limited to no more than 3 inches below the top of the dam flashboards or the dam crest if flashboards are not in place. 径流式 operations and impoundment water surface elevations are monitored in accordance with a Flow Monitoring Plan. Minimum flows of 20 cfs at 坝 #1 and 8 cfs from Dam #2 are provided into the bypassed reach except during walleye spawning season when a combined minimum flow of 105 cfs must be released below the two dams. A minimum flow of 30 cfs is provided to the Island Branch via a notch in the weir. These flow levels were determined by a demonstration flow study conducted at the time of licensing and consultation with the resource agencies.

项目附近的奥斯威戈奇河被指定为A级水。A级水的最佳用途是作为饮用水、烹饪或食品加工的供水，以及初级和 二次接触娱乐和钓鱼。该项目河段未被纽约州环境保护部列为受损河段，径流式作业不会影响水质。

There are no migratory fish in the project reaches due to the presence of several downstream dams as well as natural falls that block upstream fish movement. Resident fisheries of the Oswegatchie River in the Project vicinity consist of a mix of warm and cool water species. The most abundant species captured during the surveys were rock bass, fallfish, and pumpkinseed. The low intake approach velocity of 0.89 ft/second allows most fish to avoid 夹带 in the turbines. In addition, many smaller fish that might not be able to outswim the approach velocities are often small enough to avoid turbine blade strikes and pass through a powerhouse unharmed. Additional fish protection measures included modification of the outflow of the sluice gate to minimize injury to any fish passing downstream via the 20-cfs minimum flow at Dam #1; provision of an adequate 瀑布水潭 (at least 1 foot of depth for every 4 feet of drop), a smooth surface in the bypass sluice, and adequate dispersal of flow through the sluice to provide sufficient depths for safe fish movement; and consultation with Interior and NYSDEC regarding the need for trashracks with a maximum clear spacing of 1 inch when the existing trashracks need replacement, which has not yet occurred.

Project lands encompass about 2 acres for the impoundment and about 0.5 acres surrounding the facility. There are no lands of ecological significance and no critical habitats located in the vicinity. The run-of-river operations and impoundment restrictions limit fluctuations in impoundment water surface elevation that otherwise could contribute to shoreline erosion. Erosion and sediment control measures and monitoring are followed during routine maintenance or construction activities.

The only federally threatened or endangered species that could be present in the project vicinity is the Northern long-eared bat. Several migratory birds may be present in the Project areas and include belted kingfisher, black-billed cuckoo, chimney swift, golden-winged warbler, and wood thrush. The project’s small footprint and lack of need to cut trees limit any potential impacts to these species. Only dead trees around the impoundment may be cut if they pose a hazard to navigation or project operations.

目前尚无已知的地上或考古资源列入或有资格列入 国家历史遗迹名录 in the Project area. No traditional cultural properties have been identified. However, due to the age of the dam and powerhouse, it is possible that they could be eligible for listing, subject to determination of historical relevance. The State Historic Preservation Officer (SHPO) reviewed the project at the time of relicensing and determined that there would be no effect on cultural resources. In the event any archaeological or historic sites are found during operation and maintenance of the Project, the owner consults with the SHPO and preparation of a cultural resources management plan.

Recreational facilities include a car-top boat access in the impoundment and a parking area near the powerhouse that leads to bank fishing access at the Hailesboro No. 3 impoundment. Recreational access is provided free of charge.
