Mud or fine silt poses a risk to fish such as trout and salmon. These fish lay their eggs in coarse gravel where they develop slowly over the winter. If the gravel bed is buried in silt .... the eggs or developing young suffocate.

Watercourses near developed areas are impacted heavily by siltation related to development. Precipitation runoff from paved or hardened surfaces is rapid, causing soil erosion. "Muddy" water enters the river and, in areas where the current slows, mud or silt sinks to the bottom.

The SRA works to prevent and/or reduce the input of silt to the Sackville River system and to facilitate the migration of fish through developed areas.
