Black Lake

About This Priority Conservation Area

Black Lake is the largest lake in St. Lawrence County with 63 miles of shoreline and a depth ranging between 8 and 40 feet (NYSDEC).  Located in Morristown, the Water flows into the Lake from the Indian River, Grass and Black Creeks, and flows out of the Lake into the Oswegatchie River which connects to the St. Lawrence River. 

The lake is regularly utilized for fishing and as a vacation destination, and large portions of its shoreline are developed with cottages and camps. Public access to Black Lake is provided in several locations.  An improved concrete boat launch, maintained by the NYS Office of Parks, Recreation and Historic Preservation (OPRHP), is located on the northwestern shore of the lake off County Route 6. An unimproved car-top boat launch is located along State Route 58 near the hamlet of Pope Mills allowing access to Fish Creek approximately one mile upstream of the eastern shore of Black Lake. Shoreline fishing and informal launching of small watercraft are possible from a small island where Route 58 crosses a narrow northern section of Black Lake. Although Lonesome Bay State Forest approaches the southern portion of Black Lake, the shoreline itself is private property and public access to the water is not readily available from State Forest lands.

Tier List Species Recorded at This PCA

These invasive species tiers guide management priorities in New York State and are utilized by the Partnership For Regional Invasive Species Management or PRISM Network. The species categorized in each tier are dependent on species distribution, abundance, and management options available, and may vary depending on the region. The species listed below are the species categorized in the SLELO PRISM region. View a full list of tiered species in the SLELO PRISMLearn about New York State Invasive Species Tiers and view a Story-Map

Tier 1 Species

Early Detection/Prevention

The management approach is Early Detection & Prevention. Species are not known to be in the SLELO region but are within 100 miles and an introduction pathway exists. 

Species Recorded at This PCA

No Tier 1 Species were found at this PCA at this time. 

Tier 2 Species

Eradication

Management Approach is Eradication. Species are known to be present in the SLELO region but are in low abundance with suitable treatment methods available to make eradication feasible with Priority Conservation Areas. 

Species Recorded at This PCA

No Tier 2 Species were found at this PCA at this time. 

Tier 3 Species

Containment/Exclusion

The management approach is containment and exclusion. Species are too widespread for eradication from the region, but some areas remain unaffected. Targeted management can be used to suppress the population within Priority Conservation Areas. 

Species Recorded at This PCA

Phragmites

Tier 4 Species

Suppression/Local Control

The management approach is suppression and local control. Species are present and widespread throughout the region with no chance of eradication. Localized management is applied to protect high-priority resources like rare plant habitats or recreation areas. 

Species Recorded at This PCA
  • Curly-leaved pondweed
  • Eurasian water-milfoil
  • European frog-bit
  • Purple loosestrife    
  • Zebra & quagga mussel                 

Tier 5 Species

Monitor

The management approach is to Monitor. Species may or may not be in the region but are difficult to respond to or require more knowledge of distribution, and management options. 

Species Recorded at This PCA

No Tier 5  species were found at this PCA at this time. 

Species Recorded at this PCA that are not listed in SLELO PRISM's Tiers

  • Brittle naiad
  • Banded mystery snail
