  1. Bruce Ballentine Drag Lake

    Interesting that Mon on my way back from Toronto the trent at Bolsover was up to the lawns and dock edges. In other words close to flooding. Yet our lakes are down 3 ft.

  2. Appreciate you sharing your observation. At this time of year TSW is rapidly drawing down the reservoir lakes to achieve their winter set levels, causing high water flows. This final draw down must be completed by early October to not adversely impact the lake trout spawning.
