Our mission is to preserve the environmental integrity of Pike Lake and the contiguous area, guaranteeing the ongoing availability of the lake for recreational use. We also wish to serve as a vehicle of information regarding the interests of the property owners who live around and on Pike Lake.

AIS Inspections (THank you Canosia TOWNSHIP)


The 2017 public landing educational inspections are underway.  The Pike Lake Association is very grateful for Canosia Township’s management of the program.  Please thank your Canosia Township Supervisors.  The total budgeted hours for 2017 are 1200 for Pike Lake and 800 for Caribou Lake.  The program is staffed by eight certified inspectors managed by Alyssa Hagemeyer.

The inspectors received all day training and were tested on Saturday May 6, 2017 at the Canosia Town Hall. All inspectors were given a written exam and were required to score 80% or higher to become certified.

The training was done by Jessica Moore of the MN DNR. She is an AIS Trainer. Also on hand was a MN DNR officer, who brought a boat to the training site. This allowed the inspectors to have firsthand training on what, and where, to look for invasive species.

Canosia Township is Supervising the AIS Program. You may direct any questions to Kevin L. Comnick, Canosia Supervisor @ 590-6473. E-mail is comnick@msn.com.


Current Algae Bloom

On June 12, Elaine Ruzycki of the Center for Water & the Environment from the Natural Resources Research Institute examined a specimen of Pike Lakes current algae bloom. She identified the algae as Spirogyra, a genus of filamentous green algae. Spirogyra can be found in most any lake or pond.   This type of algae is not dangerous to humans.  However high concentrations are a nuisance and can clog filter intakes.   Potential causes and mitigation information available in next newsletter.

Excessive phosphorus in surface water leads to an overabundance of algae and other aquatic plants.

Look for the middle number: The three numbers on a fertilizer container lists its percent nitrogen, phosphorus and potassium content, in that order. A zero in the middle means a phosphorus-free fertilizer.

Excessive phosphorus in surface water leads to an overabundance of algae and other aquatic plants.

Phosphorus levels in soils are measured in parts per million (ppm). In lakes and rivers, phosphorus levels are measured in parts per billion (ppb) – a unit 1,000 times smaller. This gives an indication how sensitive lakes and rivers are to additional inputs of phosphorus. Where it takes 25 ppm of soil phosphorus to grow healthy turf, 25 ppb – a quantity 1,000 times smaller can promote excessive algae growth in lakes.

This sensitivity of lakes and rivers to phosphorus means even small sources of phosphorus in runoff, that by themselves may seem inconsequential, can result in water quality problems when combined with other similar sources across a watershed.

Pike Lake had chloride concentrations considerably higher than the ecoregion expectations. This is most likely due to “urban” runoff.

PIKE LAKE HISTORY / 100 years after fire 

Audrey Eaton (fall of 2012) speaks of great fire of 1918 that hit Pike Lake, near Duluth MN.
