St. Croix River

St. Croix River

There is currently no streamlined on-line system for the pubic or internal users to view all data collected within the St. Croix River Watershed.

Fish counting at Milltown Dam has been in place since 1981 and is a method of establishing an approximate count of the anadromous fish entering the St. Croix River at the lowermost dam located in St. Stephen, NB.

Several different entities and governments, including the IJC, are responsible for the management of, and setting regulations, permits and other requirements for the waterbodies within the St. Croix River watershed.

This project is a 3-year study to better understand stressors affecting water quality in the St. Croix River watershed including nutrient concentrations and their distribution. It will also inform enhanced water quality monitoring in the basin.

Fish counting at Milltown Dam has been in place since 1981 and is a method of establishing an approximate count of the anadromous fish entering the St. Croix River at the lowermost dam located in St. Stephen, NB and operated by NB Power Milltown Hydro Power Generating Station (Milltown Dam).

The Sipayik Environmental Department (SED) of the Passamaquoddy Tribe at Pleasant Point, Maine, in parallel with the yearly fish counts, conducted this multi-year study to determine the effectiveness of fish passages in the watershed in 2016 and 2017.

The East Grand Lake Basin in eastern Maine and southwestern New Brunswick drains an area of 132 mi2. The impoundment provides storage for hydropower operations and the maintenance of minimum streamflows on Forest City Stream for environmental compliance.

Anadromous fish have been counted at the research trap at the Milltown dam fishway since 1981. This project forms the basis for measuring the progress of current international efforts to restore sea-run alewife, blueback herring, and American shad to the St. Croix River watershed.

The project would be a 4-year study to better understand stressors affecting water quality within the St. Croix River, and to undertake enhanced water quality monitoring in the river with a particular focus on understanding nutrient concentrations and distribution in the watershed.
