The Narraguagus River is well known among fishermen and canoeists for its recreational aspects, but has received little scientific attention.

Bryant (1952) conducted a general survey of the watershed to obtain specific information on the accessibility of the river and its tributaries to salmon migration and to determine the distribution and abundance of spawning and rearing areas. river discharge, water temperature, obstructions to fish migration, and pollution sources were also recorded.

Hofmann (1966) assessed Atlantic salmon production in two nursery areas and evaluated the benthic macroinvertebrates community as a protein food sources for salmon parr.

Mingo (1978) determined the identity and concentration of pesticide residues in the aquatic ecosystem and assessed the impact of those residues on the benthic community in riffle areas. Included in that study was a survey of aquatic insect fauna of the east branch of the river and of selected tributariesThe results of that survey form the basis for this bulletin.
