Getting Across: Aquatic Organisms and Road-Stream Crossings, A Brief Introduction

Many culverts act as dams, or have water depths and flow velocities that otherwise block the passage of fish and other aquatic organisms. Not only does the health and diversity of the watershed depend on free passage upstream and downstream, but the Endangered Species and Clean Water Acts mandate free passage for aquatic species. This video explains why and how fixing culverts at road-stream crossings will restore habitats.
