July is Lakes Appreciation Month and we’re celebrating with a contest! To raise awareness about water quality, we're encouraging people who enjoy lakes to participate in a "Secchi Dip-In" for a chance to win a $100 gift card and a one-year membership to the North American Lake Management Association (NALMS). What is the “Secchi Dip-In”? The "Secchi Dip-In" is an annual citizen science event created by NALMS in 1994. It was developed in order to involve lake-goers and associations across North America in using a simple Secchi disk to monitor the transparency or turbidity of their local waterway. This data collected is evaluated on a regional scale by NALMS and helps lake managers further understand the water quality of lakes in their region. Since 1994, more than 10,000 trained volunteers have generated 42,000 transparency records, giving a glimpse of lake water transparency at sites across North America and the world, according to NALMS. How do I collect a Secchi sample? Click below to watch a video demonstration from Senior Aquatics Manager Christopher L. Mikolajczyk, CLM. Chris explains how to properly use a Secchi disk, how to read the results, and how this simple method helps inform lake and pond management strategies. [embed]https://youtu.be/cj7YEctvqRQ?si=BxaOu4DqoA5alCWi[/embed] If you'd prefer to read (vs. watching), we've got you covered with these step-by-step instructions: 1. What is a Secchi disk and what data is collected with it? The typical Secchi disk used in lakes is an 8-inch disk with alternating black and white quadrants. It’s lowered into the water until the observer can no longer see it. The depth of disappearance, called the Secchi depth, is a measure of the transparency of the water. The disk is named in honor of Father Pietro Angelo Secchi, astronomer and scientific advisor to the Pope, who tested this new instrument in the Mediterranean Sea on April 20, 1865. 2. Where can I get a Secchi disk? Secchi disks are a low-cost investment and a great tool to have for measuring water quality. You can purchase a Secchi disk on the internet for $20-$30. Alternatively, you can always ask a friend or your local lake manager to borrow one. Some people even make their own! 3. How do I take a measurement? How many times do I do it? A measurement is taken by lowering the disk on the sunny side of the boat. To eliminate sun glare, an underwater viewer (viewscope) can also be used if so desired. Allow sufficient time (preferably 2 minutes) when looking at the disk near its vanishing point for the eyes to adapt completely to the prevailing luminance level. Record the depth at which the disk disappears. Slowly raise the disk and record the depth of reappearance. The “Secchi depth” is the average depth of disappearance and reappearance. For further accuracy, several people can each record several Secchi depths. Then, all of the depths can be averaged into one single reading. Please note: the water depth should be at least 50% greater than the Secchi depth so that the disk is viewed against the water background, not bottom-reflected light. 4. What's the best time of day to collect a sample? The best time of day to collect a sample is when the sun is at its highest point in the sky, generally around midday. Most volunteers generally collect data between the hours of 10:00 AM and 2:00 PM. 5. What do the results mean? The Secchi disk measures transparency, which serves as an indicator of changing water quality. Transparency decreases as the amount of particles in the water— such as algae and sediment—increases.

One lucky winner will be randomly selected on August 1, 2018. The selected winner will receive a $100 gift card to Amazon and a one-year membership to NALMS. We’ll reach out to you via social media to collect your email and address for prize distribution. If the winner does not respond within 5 working days with the appropriate information, we will select another winner at random. Good luck, everyone!

We’re thrilled to announce that Princeton Hydro Founder Dr. Stephen J Souza received the North American Lake Management Society’s “2017 Lake Management Success Stories Award” for his work with Lake Mohawk.
While accepting his award Dr. Souza stated, "this would not have been possible had it not been for the foresight of the Lake Mohawk Country Club and the support we have received over the years from the Lake Board, the current General Manager Barbara Wortman, Steve Waehler and the Lake Committee, Ernie Hofer and Gene DePerz of the Lake Mohawk Preservation Foundation, and of course the late Fran Smith."
Steve went on to thank his staff at Princeton Hydro, especially Chris Mikolajczyk and Dr. Fred Lubnow, for their efforts over the years "collecting and analyzing a variety of lake data and implementing the innovative restoration practices responsible for the lake's water quality improvements."
Since 1990, Dr. Souza has worked with the Lake Mohawk Country Club and the Lake Mohawk Preservation Foundation to develop and implement successful lake management strategies to restore and protect the health of the lake and its surrounding watershed.
The NALMS award recognizes an individual or team with notable accomplishment of lake and reservoir management efforts that demonstrate improvements in lake/reservoir condition or watershed management in a cost-effective manner.
Many thanks to Lake Mohawk for the continued partnership and steadfast commitment to water quality. And, thanks to NALMS for bestowing Dr. Souza with this great honor.
