Bob Lake Preferred Water Level Survey

The BLA is working with the Coalition for Equitable Water Flow (CEWF) to provide information to the Trent Severn Waterway (TSW) on the impact of different water levels on property owners on Bob Lake.

Demands on the Trent Severn Waterway are continually increasing and we believe it is important that it be more aware of the impact of its operations on lake residents. This survey is part of a major effort by the CEWF to collect lake specific information on the Reservoir and Flow Through lakes in Haliburton County.

The primary period of concern is mid-May to mid-September (“the Navigation Season”). The Survey Form below will permit a property owner to record the impact of water levels on that owner’s property above and below the water level of Bob Lake on the date the Survey Form is filled in. (This is called the Date of Reference Water Level on the Form).

The impact of Higher Water Levels may include but is not limited to:

  • Low-lying cottages flooded
  • Shoreline erosion greatly increased
  • Wetlands swamped – nests flooded, habitat degradation
  • Clearance at bridges reduced
  • Unmarked navigational hazards hidden
  • Difficult to install and access certain styles of dock

The impact of Lower Water Levels may include but is not limited to:

  • Access to ‘water access’ properties restricted
  • Inability to remove boats from boat lifts
  • Inability to trailer boats at boat launches
  • Water intake lines prone to freezing, especially in areas with shallow shorelines
  • Unmarked navigational hazards created
  • Wetlands dry out
  • Damage to exposed shoreline, especially on shallow lakes, leading to barren zone between high and low water marks

The survey below contains four sections:

  1. Property & Owner Contact. This section also includes the date when water level measurements were taken.
  2. The impact (up to four instances) that would occur if water levels rise ABOVE the measurement taken. For example, if the water level were 6 inches higher, the bottom of your fixed dock would be under water, enter 6 as the “Number of inches ABOVE water level on reference date when an impact would occur“, and “The bottom of my fixed dock would be submerged in water” as the “Description of impact referenced above“.
  3. The impact (up to four instances) that would occur if water levels drop BELOW the measurement taken. For example, if the water level were 4 inches lower, your fixed water intake would be above water, enter 4 as the “Number of inches BELOW water level on reference date when an impact would occur“, and “My fixed water intake will be above water” as the “Description of impact referenced above“.
  4. A list of other water management issues/concerns you may have.
