The large number of visitors to this site discourages the presence of mammals and reptiles. Most of the animals that can be seen are avifauna and ichthyological fauna. The birds relatively common here and therefore most often seen are the red-winged blackbird (Agelaius phoeniceus), cliff swallow (Petrochelidon pyrrhonata), barn swallow (Hirundo rustica), ruby-throated hummingbird (Archilocus colubris), European starling (Sturnus vulgaris) and American robin (Turdus migratorius). In addition to these species, many other migratory birds can be spotted around the site.
Across from the site, in the Sainte-Anne-de-Bellevue Rapids, the government has set up a fish sanctuary. The goal is to protect spawners, which gather in large numbers at certain recognized spawning sites.
Of the 23 fish species that visit the rapids, 12 are of particular interest. The most commonly found are the pumpkinseed (Lepomis gibbossus), brown bullhead (Ictalurus nebulosus), smallmouth bass (Micropterus dolomieui), northern pike (Esox lucius), common carp (Cyprinus carpio), European perch (Perca fluviatilis) and maskinonge (Esox masquinongy).
