Zebra Mussels

 Zebra Mussels Threaten Northern Lakes from Cottage Life. The article is available here.

Lake Partner Program

As you may or may not know, I have been designated the Lake Partner contact for Echo Lake. As such I am expected to take water quality measurements once a year in the spring, and then water clarity and temperatures measurements hopefully twice a month. I will endeavour to keep you all informed of the current numbers via this page. I have marked the location of the sample point (the deepest part of the lake - 45 feet / 13.7 m) on the map below. A special thanks to Dr. Truscott for providing me with that point courtesy of his fish finder. 

Why measure water clarity and phosphorus?
