Goodfish Lagoon Wastewater Treatment Plant, County of St. Paul, Alberta

Goodfish Lagoon is a wastewater treatment facility located on Range Road 125 in the County of St. Paul, Alberta, Canada. It serves a small rural population of 512 residents, reflecting the dispersed settlement pattern typical of the region. The plant is classified as a lagoon system, a common treatment approach in sparsely populated areas of the Canadian prairies. The plant provides secondary treatment, which meets the baseline standard for municipal wastewater in Canada under the federal Wastewater Systems Effluent Regulations (WSER). These regulations require secondary treatment or equivalent for all systems discharging to surface water, with additional monitoring for effluent quality. For a small community like County of St. Paul, lagoon-based secondary treatment is a cost-effective and reliable solution. The treated effluent from Goodfish Lagoon is discharged into local surface waters, likely a small creek or tributary within the North Saskatchewan River basin. The North Saskatchewan River flows eastward through Alberta and Saskatchewan, eventually draining into Lake Winnipeg via the Saskatchewan River system. This watershed supports diverse aquatic life and is important for regional water supply and recreation.

The plant discharges into a local watercourse within the North Saskatchewan River basin, which ultimately drains into Lake Winnipeg. This watershed is ecologically significant, supporting fish species such as walleye and northern pike, and providing habitat for migratory birds. The region's cold climate and seasonal flow variations require careful management of effluent to protect downstream water quality.
