Endangered Atlantic Salmon, the COSWIC listed American Eel and their 'critical habitats'. The Avon River Causeway has 'zero' fish passageway. Thus, impeding all fish species needing to migrate to their freshwater habitats, in order to complete their lifecycles. FAR reviewed and supported a report to have a more indepth study regarding the protection of fish species before the expansion of gypsum quarries within the river's watershed because of threats to river life, citing the use de-watering runoff from the quarries.

Within seven years, a four metre high island of silt formed on the seaward side of the causeway; and the effects were felt 20 kilometres downstream, where two metres of mud impaired navigation at

The causeway controls the Avon River's discharge and the incoming tidal waters of the Minas Basin through a series of flood control gates which are intended to regulate the river's flowage to prevent flooding of agricultural lands upriver near

Dr. Michael Risk of the
