Land Use Planning Study Township of McKellar

Environmental Component

Objectives

1.

Assess water quality of McKellar lakes

2.

Identify fish habitat along shoreline

3.

Evaluate recreational potential based on boating capacity

4.

Determine capacity to further development based on trophic state

5.

Recommend policies in context of environmental opportunities and constraints

Historical Data Search

Data collected included: water chemistry,

lake capacity assessments, fisheries, fish habitat, lake bathymetry, access, etc.

Data collected from the Ministry of the

Environment in Sudbury and the Ministry of Natural Resources in Parry Sound.

Some information still to be obtained (i.e.

wildlife habitat, species-at-risk).

Water Chemistry Sampling

2 rivers Manitouwabing and

Middle

17 lakes Simolea, Ryan, Mary

Jane, McKellar, Moffat, Oliver, McEwen, Armstrong, Little McKellar, Blackwater, Manson, Robinson, Manitouwabing, Little Ruebottom, Fresque, Hyde and Acton

Water Chemistry Sampling

Sites chosen based on bathymetry (i.e. Manitouwabing n=6,

Acton n=1).

Dissolved oxygen and temperature profiles Secchi disk (water transparency) Water chemistry parameters included:

Total phosphorus (shallow and deep water samples if

appropriate)

pH, alkalinity Colour, turbidity, total suspended solids, conductivity, dissolved

• rganic carbon

Total kjedahl nitrogen, nitrate, nitrite

Shoreline Assessments

Fish habitat

Aquatic plant beds, fallen trees, spawning

substrates, inflows

Boat counts and capacity analysis

Skiffs, runabouts, personal watercrafts, canoes,

windsurfers, sailboats

• Number and type of boat that cross centre

line transect cumulatively between 10:00 am and 6:00 pm.

• A snapshot of the number, speed and type
• f boats in study area every 10 min.

Next Steps

Compare water quality data with historical

levels, Provincial and Federal Water Quality Objectives, etc.

Determine sensitivity of lakes to development

based on water quality and recreational boating

Prepare atlas of McKellar lakes Assess data to identify opportunities and

constraints to development (i.e. policy implications)
