Geographic Location:

Township: Toronto
Watershed: Don River
Stream Size: 4th order
UTM Grid Coordinates: 17 631988 E 4838351 N		  

Purpose:

Allow fish passage upstream, increase habitat diversity and improve aesthetics.

Objectives:

The Don River Fisheries Management Plan establishes the section of river where barriers for migratory species moving upstream are located. These barriers had to be mitigated to allow passage of migratory salmonids to suitable spawning habitat.

Description:

A 2m high barrier was mitigated to allow fish passage by constructing a series of pools and riffles on the downstream reach. Riffles were spaced based on the stream geometry and constructed of large armourstone and fieldstone to withstand flood and ice.

Estimated Cost: $200,000 Construction Date: 1997 Volunteer Effort: 0 hrs
