Pre-'99 Conservation Work - continued . . .

Silver Creek-Cedarvale Park

Summer 1995 and 1998 CRAA built a vortex weir test project, re-enforced eroding banks and planted numerous trees and shrubs to shade the river and prevent erosion. The vortex weir created a small holding run that is used by a number of juvenile steelhead and Atlantic salmon. The reforestation work has taken hold and the willows are up to 15' tall. Water temperatures have cooled slightly and the number of juvenile salmonids using the section has increased.

Levis Creek Rehabilitation project

Summer 1998 Levis Creek is a small tributary that enters the Credit at the north end of Mississauga. There has been some salmonid reproduction in the lower 1,000 m of the river, below a dam that blocked migration. The dam was removed in the summer of 1997 which has allowed access to another 7,000 m of Levis Creek. This summer we are conducting a temperature survey, an electro-fishing survey and completing both river rehabilitation work and reforestation work. A 1,500 m section with the lower middle sections of Levis Creek has been identified by CRAA as the most important priority. The before picture below shows one of the two properties that cover the area where we have permission from the land owner to complete our rehabilitation work. The section will be forested with cedars, willows and maple. Sections of the creek with severe erosion will also receive bio-engineering work and stabilization work.

Glen Williams

Below 10th line CRAA has approached the land owner to reforest the banks of this section to shade the river and prevent further erosion of the river banks. At this time the land owner has not agreed, but we hope to receive the go-ahead by the fall of this year. This 800 m stretch of the Credit River warms by as much as 12 F (6 C) from solar heating along the length of this property. This is the highest priority site we identified in the area above Norval.

Upper Glen Williams Summer, 1998 CRAA has received permission from the land owner to reforest his property and complete some rock placement to prevent the loss of the only large willow on the edge of the river. This property is immediately below the 10th line property mentioned above. This section is not nearly as unhealthy, but still warms the water a few degrees.
