Plankton (microscopic free floating organisms) are a very important aspect of the ecology of the lakes within the Glen Lake/Crystal River Watershed. This video highlights the method by which the plankton are collected in our lakes using a plankton net along with locations in our watershed where we collect the plankton and how often they are collected. The plankton samples are analyzed in the laboratory using a compound microscope. We especially look for a rich biodiversity and whether we are encountering any invasive species. This video features Laura Wiesen and Rob Karner as the plankton peeps who do the collecting and analyzing.
Ever wonder what determines the water level of Glen Lake and consequently the water flow in the Crystal River? If so, read on. The next few paragraphs will briefly outline where the water comes from, where it goes, and the management plan philosophy we have developed to serve the Glen Lake-Crystal River community.
The water comes from the precipitation we receive throughout the year in the form of rain and snow. It finds its way into the lake two different ways: directly from the sky and through the surrounding area which is called the Glen Lake watershed. The water that flows in from the surrounding streams and underground springs (predominantly located along the East and South shores of Big Glen) contributes significantly, but water seeps in from all the hills and lands surrounding the lake. This watershed rain and snow melt filters through the surrounding properties, lawns, and forests down through the sand and gravel into the lake. Fortunately this filtration has a significant time lag so we continue to have water coming into the lake during the dry weeks of the summer. Something to keep in mind is that any chemicals, fertilizers, fuels, or septage that is spread, spilled or buried in the watershed eventually makes its way into the lakes too. So the importance of keeping ground and streams clean is obvious.
Stewardship plays a critical and grassroots role for protecting the Glen Lake/Crystal River Watershed. Doing the right thing for the lake is not always followed for a variety of reasons. In this video, the Glen Lake Association has recognized the Lymans’ home on the east shore of Big Glen as being careful to be ecologically respectful for not only their landscaping, but building their house as a LEED certified home. As you will see, the Lymans are passionate about protecting the water and setting a great example for all of us to follow that sets the stage now and for future generations that living on the shoreline has its rewards and its responsibilities. If you want more information about living in harmony with nature and protecting the water of Glen Lake, please contact the association and we will be happy to help you accomplish our common goal.
Did you miss the 2016 Discovery Boat tours? If you would like to join us in 2017, please sign-up here for free and we’ll let you know via email as soon as we schedule the boats for 2017. (We will probably know the dates in May and you can signup then.)
What is Discovery Boat? Join the Glen Lake Association Watershed Biologist, Rob Karner on a pontoon boat for a two-hour scientific study of Glen Lake. Using various scientific equipment, students learn all about plankton, water chemistry, swimmers itch life cycle, hydrology, bottom sediments, aquatic succession, and aquatic plants.
Learn about and see a plankton net, a compound microscope, Ekman Dredge, sonar devices, aqua view underwater camera, and the hydrolab.
In this video, you will learn some of the basics of how the Glen Lake Association attempts to regulate lake levels throughout the year. Many GLA members may have never seen the dam and/or know how it is managed. Bill talks about the many factors that play into managing the dam and the technology that helps the water level committee make important decisions about lake levels that are in turn, affecting water quality. Shoreline erosion and ice damage to shorelines are among the many topics discussed along with the fall salmon run up the Crystal River.
This video was made at The Leelanau School during the Michigan Swimmer’s Itch Partnership conference. The interview is between Rob Karner, Watershed Biologist, and Ron Reimink of SiCon, LLC. This video highlights the recommendations of SiCon to the Glen Lake Association for the next 8-10 months as it relates to what steps should be taken to reduce swimmer’s itch. Ron Reimink is the world’s leading researcher with respect to Common Mergansers and live trapping them off lakes that have swimmer’s itch. Watch and learn about this important topic for the Glen Lake Association members.
This video is filmed on location at Hatlem Pond. Watershed biologist Rob Karner interviews the engineer of Spicer Engineering. This video highlights the work being done during the fall of 2016 that will measure the sediment that has been “trappped” by the pond upstream from the dam. Once we know the depth of the pond after two years of dredging it, we can determine how fast the pond is filling up again and forecast how long it may take before a decision is made for another maintenance dredge to happen sometime in the future. Stay tuned for the results of this important study.
Meet our new president Bill Witler. In this video, he talks about what being a GLA president means to him along with his short- and long-term goals are. This is a chance to meet him as he is interviewed by Laura Wiesen aboard the GLA’s “Lake Guardian” boat on Big Glen.
Welcome to our newly redesigned Glen Lake Association website. Our aim with this site is to make information easier to find and to be more responsive to member needs.
We also are offering significant technology enhancements that enable us to reduce administrative costs and improve recordkeeping. While the majority of our membership (72%) prefers email correspondence, we will maintain our regular mail communications for those members who don’t have an email address or are uncomfortable with online communications.
You can learn more about how to maneuver through the new website, how to utilize the site to pay your annual dues or make a contribution, view community calendars and the current GLA newsletter and learn how to register for upcoming
events at our annual meeting Aug. 13. An “easy steps” information card will be available on how to understand the site for everyone in attendance at the annual meeting.
