May 30, 2017 – Credit Valley Conservation (CVC) confirms water levels at Island Lake Conservation Area have returned to normal following last summer’s drought. It was the most severe dry spell recorded in Southern Ontario in a decade. These conditions had many concerned about the long-term impact on the reservoir and the health of fish in the lake.

“The combination of winter snow-melt and spring rain has brought water levels in the reservoir back to seasonal levels,” said Tim Mereu, Director of Watershed Management at CVC. “We constantly monitor water levels to ensure consistent flow from the reservoir into the Credit River.”

The main purpose of the reservoir is to support the operation of Orangeville’s wastewater treatment plant, located south of the reservoir. CVC is required by provincial law to operate the dam so enough water flows into the Credit River to dilute discharges from the wastewater treatment plant. The water flow is necessary to make sure the river remains clean, and fish, insects and other wildlife can thrive downstream.

The reservoir also provides a very important recreation space in the community.  Fishing is among the most popular activities at Island Lake Conservation Area. Each year the park attracts local and out-of-town visitors for its annual bass fishing derby held in July.

“Low water levels can cause stress to fish and aquatic life,” said Bill Lidster, Manager of Conservation Parks at CVC. “We know there is no evidence that last summer’s drought had a negative impact on the fishery. This is very good news with the 2017 fishing season now underway.”

Island Lake is home to a variety of fish species including Northern pike, largemouth bass, yellow perch, black crappie and sunfish. Island Lake Conservation Area is one of CVC’s most popular parks. In 2016, it welcomed more than 231,000 visitors through its gates.

Credit Valley Conservation (CVC) is one of 36 conservation authorities in Ontario. Conservation authorities are provincial/municipal partnerships that manage the natural environment of a watershed, an area of land where the rain and snowmelt drain into a body of water. For more than 60 years, CVC has worked with its partners to build a thriving environment that protects, connects and sustains us. CVC is a member of Conservation Ontario.
