What a lake page holds
The sections are the same on every lake, in this order. A section with no record for that lake is left out rather than filled. Each is read from a named public record, and the page says which. The examples here are one lake’s own.
Surveyed depths
Every sounding the province took, drawn as bands of depth on the lake’s outline. The deepest is circled, with the survey year and method behind it.

The lake from above
The province’s own aerial photograph of the whole lake, in the season it was flown.

Water quality
Phosphorus and clarity at each monitored site, against the province’s own bands, season by season.
Water temperature
How a lake warms and layers through the summer, from the province’s own stations where it has them and from the nearest long-running record where it does not, labelled with the lake it was taken on.
- February, under ice
- May
- June

Fish
The species recorded, spawning areas mapped, stocking by year, the eating advice for each, and the zone’s seasons and limits.

Ice
The date an ice hut must come off, and the dates a century of records gives for the ice forming and leaving.
Getting on the water
Marinas, launches, beaches and locks, numbered on a map of the shore.

Islands and names
The islands, counted and measured, and the register’s names for every point, bay and shoal.

Questions
The questions people ask about the lake, each answered from the same records.
- How deep is Lake Rosseau?
Its maximum recorded depth is 90.1 meters, determined during Ontario’s 2000 to 2003 survey.
- How big is Lake Rosseau?
Its surface covers 62.9 square kilometers and it holds 96 islands. Of its 217 kilometers of shoreline, 139 kilometers is the mainland shore and 78 kilometers is the shore of the islands.
- What fish are in Lake Rosseau?
Ontario’s aquatic resource records name 27 species, among them lake trout, walleye, smallmouth bass, largemouth bass, northern pike and muskellunge. The lake’s spawning, consumption and stocking records also name rainbow trout and brook trout.
The lake, on paper
The same survey drawn as a wall map, in two colourways, with a place of your own marked on it.


Lake maps
Each lake, drawn as a wall map
Every depth sounding in the province’s survey, drawn as bands of colour on a printed sheet, with the named places and the ways onto the water. Printed to order in two colourways and four sizes, and a place of the customer’s own can be marked on it.

The buyer’s report
One property, read from the public record
A report on one rural or waterfront property: Crown interests, flood mapping, road access, wells, wetlands and services, drawn from provincial and federal records and read by a person before it is sent.
