Welfare of Wild Animals Trapped in Agricultural Irrigation Systems

Irrigation canals, pumping systems, and water storage facilities trap and kill millions of small animals annually, with limited awareness of the problem and few mitigation measures in place.

Key Facts

Irrigation pump intakes are a leading cause of fish mortality in river-draw agricultural systems
Canal walls trap hedgehogs, turtles, small mammals, and amphibians that cannot climb out
Water storage ponds with steep sides drown deer, foxes, and other wildlife that fall in while drinking
Simple escape ramps in canals cost under 50 USD and can save thousands of animals per installation
Australia has documented programs installing escape ramps in irrigation canals with measured wildlife mortality reduction

Welfare Considerations

Agricultural irrigation systems are a largely invisible source of wildlife mortality and suffering. Animals that fall into canals cannot escape; wildlife drawn to water pumping stations are killed by intake suction; storage ponds become death traps for thirsty animals that cannot climb out. Simple, cheap modifications — escape ramps, pump screens, gently sloped pond edges — can dramatically reduce this toll. The challenge is awareness: most farmers have no idea their irrigation infrastructure is a wildlife mortality hotspot.

What You Can Do

Advocate for wildlife escape ramp requirements in agricultural irrigation system construction standards
Support organizations raising awareness of irrigation wildlife mortality with farming communities
Install escape ramps in any steep-sided water features on agricultural or garden properties
Donate to programs providing and installing irrigation wildlife mortality mitigation equipment
