In Severn Sound the low water levels, over the past
years, have had significant negative effects on shipping, pleasure craft
marinas, navigation, shoreline properties and habitat. It is vitally
important that we understand the water level fluctuations in Severn
Sound in comparison with other points in Georgian Bay-Lake Huron-Lake
Michigan. As Midland Harbour is one of the few active federal ports on
Georgian Bay, it seemed logical that we have a water level gauge.
The Severn Sound Environmental Association (SSEA)
submitted a proposal to install a water level gauge in the Midland
Harbour to the Canadian Hydrographic Service (CHS). CHS took the
proposal to the international Great Lakes committee that oversees the
network of water level stations around the Great Lakes and the proposal
was accepted, provided funding partnership could be arranged.
SSEA joined with CHS, South Georgian Bay - Lake Simcoe
Source Water Protection Region, Lower Lakes Towing Ltd., and Unimin
Canada Ltd. to design, fabricate and install a water level gauge in
Midland Harbour. The Town of Midland is providing space at the Town
Dock and hydro for the station. The gauge will provide accurate water
level information for all users of Severn Sound waters. Ships entering
Midland Harbour will have the best information on fluctuating water
levels for safe and economical operation.
Over the long-term CHS will maintain and operate the
station to provide internet summaries and instantaneous voice
communication. The station can be accessed by visiting the CHS Lake Huron Water Levels web site,
where anyone can obtain hourly water levels or by phone - (705)
526-6413 - to hear the instantaneous water level and the high and low
water level over the past 12 hours at the Midland gauge. The project
will be of great benefit to the community and should serve as an
important source of information to commercial shipping and pleasure
craft using Midland Harbour for years to come. The data from the station
will also be useful for supporting hydraulic models of municipal
surface water intake protection zones, for mapping of Severn Sound
nearshore habitat and for use in assessing the impact of municipal
sewage discharges in Severn Sound.
