Welcome to Basin Bay

See below to learn about the characteristics of your bay and what they mean for your water quality.

Basin Bay Profile

Basin Bay

Located in the Town of Bolton in Warren County, the Basin Bay watershed flows into the Dome Island sub-basin of Lake George. This sub-basin is named for the famous dome-shaped island and contains the deepest location in the lake.

The Critical Environmental Area (CEA), a band of land extending back 500 feet from the shoreline and considered the most influential land to the lake's water quality, makes up 10.5% of the watershed (152 acres).

  • Properties: Roughly (28%) of the properties in the watershed are within the CEA (77 of 270).
  • Streams: There are nearly 3 miles of DEC regulated AA-Special streams in the watershed. There are almost 14 miles of intermittent streams that only flow during portions of the year (Spring runoff or rain events) or run year-round and are unregulated by DEC at this time.
  • Roads: 11 miles of roads: including 5.8 of Town roads, 2.8 of Private roads, 1.1 miles of County roads and 1.2 miles of State roads. There are 0.8 miles of roads within 100 feet of the shoreline and they are at a greater risk for introducing salt and other runoff to the lake.

Impervious Surface Is Impacting Water Quality

8% of the land in the CEA is covered by impervious surfaces such as roads, roofs, or driveways. Impervious surfaces covering more than 10% of the CEA will have an impact on water quality. You can improve your water quality by avoiding further impervious surface development, capturing any stormwater runoff between these surfaces and streams or the lake shore, and converting existing surfaces into something that water can sink into, like permeable pavers. Consider planting a shoreline buffer as a protective cushion for the lake.

Map of likely private septic systems in Basin Bay, NY

Septic Systems

Nearly 80% of properties (214) in the Basin Bay area are on private septic systems. Improperly treated wastewater from aging, failing or inadequately designed septic systems is impacting Lake George water quality, threatening human health with organic matter, bacterial and viral pathogens, and feeding algae growth with excess nutrients, like nitrogen and phosphorus, that can potentially lead to harmful algal blooms (HABs). If you’re a septic system owner, Lake George needs you to contribute to water quality protection by taking the actions outlined in the link below to ensure your septic system is operating properly.

Forest cover in Basin Bay

Areas to Protect From Development and Hemlock Woolly Adelgid

Nearly 91% of the watershed's area is forested. The forested areas cover approximately 1,317 acres and protect Basin Bay's water quality by providing cover and breaking up rainfall while their roots systems create soil conditions that allow for greater infiltration. It's an important area to protect.

49% of the watershed has steep slopes. Logging, a large tree die off, and development would all likely lead to additional stormwater runoff. Most steep slopes are upland of State Route 9N.

Hemlock Woolly Adelgid (HWA) is slowly spreading around the Lake, threatening the health of our Hemlock forests. Approximately 34% of the tree cover is Conifer (evergreen) trees, some of which are Hemlocks. Hemlock stands within your watershed have the potential to become infested without proper monitoring and management. The closest confirmed infestation is 0.35 miles from your watershed. HWA often spreads via birds and will likely arrive around Basin Bay soon.
