Lake Partner Program – LPP

There are two measurement points. Site 1 is in the arm of North Otter that connects the Salmon Lake Road culvert and the rest of the lake (opposite the Evans’ property). Site 2 is near the Scout camp. Both sites measure around the middle/deepest part of the lake.

Cyanobacteria (Blue-Green Algae)

The Kingston Field Naturalists (KFN) has recently put online a workshop on blue-green algae (BGA). It was made by a KFN member and two Queens students and consists of two videos on YouTube. The first covers mainly research into BGA and runs for 53 minutes, and the second deals with identifying different cyanobacteria and runs for 20 minutes.

These are particularly relevant as they cover research carried out at Queens on nearby Dog Lake. Some of the content is quite technical, but there is a lot to learn if you are interested.

The videos are:

Otter Lake Binder Records

The Otter Lake Binder Records contain an informal record of the state of Otter Lake and its natural history, as reported by NSOLA members at each AGM.

If you were not able to fill out the form at the AGM and would like to add your observations to the record, the blank form is available here. Please download the form and when completed email it to Pam Wheaton (the address is on the form).

Here are a few photos I took this year of the various stages of the gypsy moth

This 70 page document, Predators of the Gypsy Moth, was published over 40 years ago by the USDA. I’m sure some of the information is outdated, but I found it interesting to read the role that many native creatures have in controlling the gypsy moth.
