Remi Lake

Where Remi Lake is

Remi Lake lies in the District of Cochrane, with shoreline in the Township of Moonbeam.

How deep is Remi Lake?

The deepest mapped contour on Remi Lake is 15.2 meters, and the water within that boundary descends even farther. Ontario’s bathymetry record holds 33 depth contours for Remi Lake.

Surveyed Depths

Ontario has surveyed the depths of several thousand of its lakes over more than half a century. Later surveys were conducted by boat with satellite positioning and produced hundreds of thousands of soundings per lake. Earlier surveys were charted by running transects across the water and drawing depth contours by hand.

Water quality

Ontario’s Lake Partner Program is a volunteer monitoring network. Participants collect water samples for phosphorus analysis and measure water clarity through the summer with a Secchi disk. Most sites are sampled for phosphorus once a year, in spring, and some several times a year between spring and fall. Phosphorus in many lakes rises through the summer, so the two kinds of average are measured on different bases.

Phosphorus is the nutrient that controls how much algae a lake can grow. A lake with little phosphorus stays clear and supports cold-water fish such as lake trout. As phosphorus rises, algae increase, the water clouds, and oxygen in the deep water falls as the algae decay. The province classifies each monitoring site by its average phosphorus:

• Oligotrophic, below 10 micrograms per litre: clear water and low algae.
• Mesotrophic, from 10 to 20: moderately productive water, with more algae and weed growth than an oligotrophic lake but rarely a bloom.
• Eutrophic, above 20: nutrient-rich water, prone to algal blooms and low oxygen at depth.

Remi Lake has 2 Lake Partner monitoring sites. Two have reported phosphorus for the three or more years the province requires before a status is assigned. All are classified mesotrophic.

The longest record is held by site 4604/3 at N92, M96, NE end, with phosphorus sampled once a year over 7 years to 2024. Its long-term mean phosphorus concentration is 11.57 micrograms per litre, within the mesotrophic band, which runs from 10 to 20.

A Secchi disk is a white or black-and-white plate lowered on a marked line until it disappears from view. The depth at which it vanishes is the Secchi depth, a direct measure of water clarity. Clearer water gives a deeper reading.

The 2 clarity readings at site 4604/3 give a median Secchi depth of 2.8 meters.

Remi Lake Weather

The weather page for Remi Lake carries the forecast over the water, wave heights across the lake, and the modelled water temperature.

Water temperature

Ontario’s aquatic resource records class Remi Lake as a cool-water lake, with a mean depth of 3.4 meters against its maximum of 15.2.

A lake separates into layers through the summer where it is deep enough. Sunlight and wind warm and mix the upper few meters, and beneath a band of rapid cooling, the thermocline, the water stays cold. A shallow lake mixes to the bottom instead and warms through, sooner in spring and later into autumn.

No provincial monitoring station records water temperature on Remi Lake. The LastLake model computes the temperature of its surface water for each day from the daily mean air temperature at Environment Canada’s Kapuskasing Cda On climate station, 20 kilometers from the lake, or the next nearest station when its record is incomplete, and from the lake’s area of 2,490 hectares and its mean depth of 3.4 meters.

Each day’s figure carries the model’s typical error for that month on lakes of the same size. The figure in the chart below is the temperature near the surface, away from the shoreline. Bays, shallows and water deeper below the surface differ in temperature. Temperature is not measured when ice covers the lake. The weather page for Remi Lake carries the model’s figures for the past weeks and the coming week.

Fish in Remi Lake

Ontario’s aquatic resource records name 23 fish species in Remi Lake.

• Ciscotrout and whitefish
• Northern Pikepike
• Walleyeperch
• Yellow Perchperch

Spawning areas

Ontario maps 6 fish spawning records within the Remi Lake outline, for two different species, and all of them are mapped below.

By number of records

By area mapped

• Walleye5 areas16.5 ha
• Northern Pike1 area3.2 ha

The federal Fisheries Act prohibits the harmful alteration, disruption or destruction of fish habitat without an authorization, so a dock, dredging, infill or shoreline work at a mapped spawning area is reviewed on that basis.

Stocking history

Ontario’s stocking records for Remi Lake run from 1947 to 1995 and hold 12 releases. Walleye account for most of the fish: 1,070,014 released in five of the years between 1947 and 1995. The last recorded release was 64,000 walleye frys in 1995.

The province’s record of stocking for recreational fishing, kept from 2016, lists no release into Remi Lake.

Eating the fish

The 2026 Guide to Eating Ontario Fish carries consumption advice for four species taken from Remi Lake, tested for contaminants at a sampling location in Gurney & Fauquier Twps., Cochrane Dist. Each figure below is the most meals a month the guide advises for a fish of that length. Where mercury sets the advice, the figure falls as the fish gets longer, because mercury accumulates over a fish’s life. Where the guide has no result yet for certain contaminants at a location, it sets a precautionary limit of 16 meals a month. A zero means the guide advises no meals of that fish at that size.
