Where Kamaniskeg Lake is

Kamaniskeg Lake lies in the County of Renfrew and the County of Hastings, with shoreline in the Municipality of Hastings Highlands and the Township of Madawaska Valley.

How deep is Kamaniskeg Lake?

The deepest mapped contour on Kamaniskeg Lake is 39.6 meters, and the water within that boundary descends even farther. Ontario’s bathymetry record holds 56 depth contours for Kamaniskeg 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.

Kamaniskeg Lake has 8 Lake Partner monitoring sites. Six have reported phosphorus for the three or more years the province requires before a status is assigned. All are classified oligotrophic.

The longest record is held by site 2223/6 at North Basin, with phosphorus sampled once a year over 16 years to 2025. Its long-term mean phosphorus concentration is 6.55 micrograms per litre, within the oligotrophic band, which extends to 10.

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 85 clarity readings at site 2223/6 give a median Secchi depth of 4.5 meters.

Kamaniskeg Lake Weather

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

Kamaniskeg Lake weather

Water temperature

Ontario’s aquatic resource records class Kamaniskeg Lake as a cold-water lake.

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 Kamaniskeg Lake. The weather page for Kamaniskeg Lake carries the LastLake model’s surface water temperature for each day of the coming week. The province’s longest in-water record is kept on eight research lakes near Dorset, sampled since 1976. A reading is taken at the surface, at one meter, at each meter to seven and then every two meters to the bottom, about every two weeks through the open-water season and about monthly under ice. The record holds 5,240 readings at a depth of one meter.

At one meter the eight lakes track one another closely. On a day when several were sampled, the warmest and the coolest lake differed by about one degree in every month of the year, and a 12 meter deep lake and a 37 meter deep lake read within 0.2 degrees of each other from June to October. The weather of the year, and not the lake, sets most of the width of the band below.

Water temperature at a depth of one meter, by half-month, on eight research lakes near Dorset, 1976 to 2025. The band holds the middle 80% of the 5,240 readings taken at one meter; the line is the median.

How depth changes the temperature

The chart below is the province’s record on Harp Lake, 37 meters deep, drawn as the median temperature at each depth for each month over 49 years. In July the water at one meter is 23 degrees, at five meters 15, at seven meters 9, and from 13 meters to the bottom under 6. By October the warm layer has deepened to seven meters and cooled to 11 degrees. In February the whole column sits between 1 and 4 degrees under the ice, coldest at the top.

Spawning areas

Ontario maps 8 fish spawning records within the Kamaniskeg Lake outline, for two different species, and all of them are mapped below. Every record is recorded as verified and presently suitable, and none is classed as sensitive.

Spawning records mapped by the province within the Kamaniskeg Lake outline. A record under 100 square meters is drawn as a dot.

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 Kamaniskeg Lake run from 1947 to 1992 and hold 63 releases. Walleye account for most of the fish: 2,685,803 released in eight of the years between 1948 and 1991. The last recorded release was 26,000 lake trout yearlings in 1992.

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

Eating the fish

The 2026 Guide to Eating Ontario Fish carries consumption advice for seven species taken from Kamaniskeg Lake, tested for contaminants at a sampling location in Bangor & Sherwood Twps., Hastings & Renfrew Cos. 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.

Kamaniskeg Lake Ice Fishing

An ice hut on Kamaniskeg Lake must be removed by March 31. The province sets dates for ice hut removal as a safety measure to ensure huts are removed before thawing occurs. One date applies to an entire fisheries management zone (FMZ). Kamaniskeg Lake lies within FMZ 15.

An ice hut must also be removed before the ice breaks up, whether or not that date has passed. The deadline clears huts from the ice ahead of the thaw and does not close the fishing season.

Registration is required in FMZ 15 for an ice hut built of anything other than fabric, and for a fabric tent covering seven square meters or more. Registration is free, and the number is displayed on the outside of the hut.

Ice In / Out Date

No ice record is kept on Kamaniskeg Lake. The province’s nearest long record covers eight lakes near Dorset, about 99 kilometers away. It holds a date for every winter since 1975, observed by eye and from cameras set on the shore.

On those eight lakes the median date of complete ice cover is December 7 and the median date of complete ice loss is April 20, a median season of 134 days.

The date the ice forms has moved later through the record: a November 26 average across 1971 to 1980, and December 11 across 2011 to 2020. The date it leaves has moved by less than a day each decade over the same period. The two charts below are drawn to one scale of 26 days, so they can be read against each other.
