Shall We Gather at the River?
Irrigation and the Future of Southern Alberta’s Rivers
BY LORNE FITCH
In the heat dome and severe low flows of 2021, our canoe left smears of colour on several barely submerged boulders of one of Alberta’s prairie rivers. These low water levels had me reflecting on the recent scheme by southern Alberta’s irrigation sector to expand irrigated acreage. I thought of the old hymn, “Shall we Gather at the River.”

The northern leopard frog is an iconic amphibian, likely the very image that comes to mind when you hear the word “frog.” This once ubiquitous resident of prairie wetlands has faced an ongoing struggle against a changing and increasingly human-centric environment.
Deadly Highway: Road and Rail Fatalities are Decimating Jasper Park’s Wildlife
