Water run-off in Brome Lake

RBL began a study in 2010 which would permit it to prioritize some of its actions and to draw up policies that would serve to protect Brome Lake. Thanks to this study, it will be possible to better understand the water run-off situation in the lake starting with the behaviour of the main tributaries when the flow is low, medium or high.

 

 

 

 

The results will permit a better response to such situations as: 

  • Does the water flowing from Quilliams Brook (the principal tributary, almost 50%  comes from this source) have much of an impact on the lake given its location so close to the outlet?
  • In the advent that fertilizer is spread in an area close to the lake, what is its probable penetration into the lake?
  • In the advent of a spill of toxic products along route 243 (chemin Lakeside), what would be the foreseeable impact?
  • How does the water flow when there is a major input of water, when there are high winds?
  • What is the impact on the lake when the gates are opened at the end of the lake (according to an agreement with Bromont, VLB must supply at all times at least 0.88 m3/sec.), etc.?

RBL mandated a team of researchers from the Engineering faculty at the Université de Sherbrooke. These specialists, hydrologists and experts in water quality in 2010 carried out a first hydraulic modelisation and hydro-dynamic phase (Quilliams watershed and the lake itself).
