Fright & Flight Zone, by Laurent Robichaud

Since 1963 the Little Long Generating Complex on the Lower Mattagami River in Northern Ontario has been the source of an environmental crisis of immeasurable proportions. Thousands of Lake Sturgeon have been entrained through spillway gates and left stranded waiting to be captured and relocated back to their adopted man-made habitat, leaving waters not fit for survival. Adam Creek Spillway is well known province-wide as a thorn in hydro electric energy and should not be defined or qualified as GREEN energy.

Mattagami River – Little Long Dam Safety Project

Turbine and entrainment mortality, although poorly documented, are recognized threats to Lake Sturgeon subpopulations within fragmented rivers and are at risk from extreme changes in water flow velocity and pressure, cavitation, shear, turbulence, mechanical injuries, entrainment and impingement.

Media Release: Putting the ‘Blue’ Back in the ‘Green’ City

GUELPH –On September 10th, with the sounds of a jackhammer hammering in the background, the Hanlon Creek monitoring weir was removed within Preservation Park in the City of Guelph. The motivation behind the removal of the weir was multi-purpose. The project objectives were to remove the weir to improve the ability of fish to migrate upstream, while simultaneously lowering the upstream water level, which will narrow the channel and result in cooler stream temperatures.

Hanlon Creek Weir Removal Project – Complete

It’s done – the barrier to fish passage has been removed.

I’m happy to report that the Hanlon Creek Weir Removal Project was completed today!!  The middle portion of the weir has been removed and the stream bed rehabilitated.  Brook Trout are now able to access an additional 3.6 km of coldwater habitat and the stream has been made more resilient to a warming climate.

Warm thanks to all our volunteers and supporters for your generosity and caring!

A great article in the 8 September 2019 edition of the Guelph Today:

Calabogie Generating Station Redevelopment – Madawaska River

Peaking operations, with the variable flow discharge and ramping patterns, the rate and frequency of water level changes, and the amount of time the station is at its maximum discharge level, can all have a significant impact on the degree of channel and bank erosion.
