Water levels on Lake Poisson Blanc

Before criticizing the management of the water level, let’s not forget … that it is thanks to this reservoir of Hydro-Québec that we can enjoy our sites on the water’s edge. Without this reservoir we would all be in a field or just near a stream. We must accept that the reservoir’s level fluctuates regularly depending on the circumstances.

EMERGENCY:

Because of climate change, we must be prepare in case of any emergency (ex: flood, forest fire… ). Do you know what to do?

IN CASE OF FLOOD ALERT

General:

  • Store objects in height or on the upper floor.
  • Store chemical or harmful products (such as insecticides and waste oil) so that it is not accessible to children.
  • Block the sewer pipes in the basement.
  • Plug the drain in the basement.

Electricity and propane gas:

  • If the water seeps into the residence, contact Hydro-Québec as soon as possible at 1 800 790-2424 to interrupt the electricity. Do not touch anything.
  • Close the faucets on the propane tanks.
  • Close the tap which is located at the outlet of the oil tank.

Outside:

Remove or secure your goods that move easily in order to avoid losing them

Explaining why our water levels keep fluctuating:

1 What is a watershed?

The big picture is that we are part of the Ottawa River Watershed, do you know what it means?

**Word of the day: WATERSHED AKA drainage basin, catch basin, hydrographic basin, etc. **

Definition: A watershed is defined as an area of land where all the surface water drains into the same place, whether it’s a creek, a stream, a river or an ocean. Therefore, all precipitation, such as rain or snow, that falls on a watershed ends up flowing to the same place.

We’re part of the La Lièvre watershed

Our watershed

We are trying our best to keep you inform threw our Facebook page! Some of you don’t understand why our water keeps fluctuating???

Here is a video clip explaining why? https://www.facebook.com/hydroquebec1944/videos/2252068134856789/

2 About the Poisson Blanc reservoir:

Our reservoir effects many municipalities along La lièvre to Gatineau then combines with other reservoirs of the Ottawa river watershed. There are three authorities governing the dams so there must be coordination between all of them.

Sadly, for us, what is considered the most important for them is the safety & security of those living in the urban areas: Gatineau, Ottawa and Montréal. For us, there is a understanding that the water level should be stable till Labour Day afterwards the water level could go down rapidly for many reasons including maintenance of the different dams.

Legally, another association (which no longer exist) tried to regulate the level of our reservoir by legal means. The reason of the legal procedures was for the shoreline erosion but not really to prolong the period when the water level is stable till the end of September. So, presently for us, If we want to guarantee a certain level we must reach all owners affected including those living up north of the Poisson Blanc. For this to happen we must prepare our case which is a long process. If you are interested in working on a committee willing to work on this project please contact us!

3 History of all the procedures that were done to regulate the level of our reservoir:

Sources are from the archives of the «Association les amis de la lièvre» (this association is no longer active) and  also COBALI.

The official act of 1992 defining our water level:

Legal procedure to stop the erosion of the reservoir presented by :

ASSOCIATION DES RÉSIDENTS RIVERAINS DE LA LIÈVRE INC

In 2006 a plan was approved for the management of the water level:

General snapshot of our watershed in 2013:

Last official communication by our Association had concerning the water level. The letter was send by Ronald Thomas (VP of Newton Bay in 2015)

Brookfield Power and the other dam managers operating in the Lièvre River watershed have a primary objective of preventing flooding on the Lièvre River as well as on the Thousand Islands River. In flood and drought periods, the goal is to manage water in a way that minimizes damage to all involved stakeholders, including riparian owners.

In the watershed of the Lièvre River, 16 riparian municipalities, their citizens and the relevant departments and agencies are now better prepared to act in the event of a disaster. Supported by Dam Managers and Regional Emergency Organization, municipalities and departments completed an emergency response planning process and shared the results of their work with the public in the fall of 2010. Although this joint plan may be useful for any type of disaster, the scenario used for the approach was that of an exceptional flood or dam failure. For more details, consult your municipality.
