Emily Heald, Water Program Coordinator at North Lakeland Discovery Center, sent an email out last week about and interesting article . . .
"Katie Hein, the scientist who has been analyzing our lake level data, wrote
an incredibly interesting article in the most recent publication of Lake Tides."

Emily is also our contact at the Discovery Center for the lake level monitoring. Here's a link to the Discovery Center that explains the procedure.
Discovery Center Citizen Lake Monitoring
Every spring they come out and install a gauge right off the shoreline. The gauge is calibrated so that readings from day to day and year to year can be compared.
This is a photo of the most current page in the monitoring booklet. On May 11 the zero point was calibrated at 305.3. You add the reading (65) to the zero point and the initial reading for 2019 was 370.3. If you add the 305.3 to the reading from today (56), you'll come up the actual level of 361.5.
At the end of each month, we submit a photo of the current month and we receive a chart (see below) that shows the lake levels for that month added on the past data.
This year Emily asked if there was one year for which she could do a graph showing the change in levels. I think 2014 is an interesting year. It started out at the highest level and, in five weeks, they had to come out and re-install the gauge in deeper water. They installed the gauge on 5/13/14 and the actual elevation was 395.7 (333.7 + 62 cm). On June 21 the actual elevation was 343.7 (333.7 + 10 cm).
As you can see from the graph, the water level kept falling throughout the summer and started climbing around August when the rain started coming again. The other interesting thing about 2014 is we had 4" of snow on October 31, a day before they took the gauge out.
The highest point since 2014 was last summer when all the docks started floating away.
There's another change this year that should be interesting. A few weeks ago they came out and did a reading that will enable them to compare our lake level to sea level and to lakes around the world. As soon as we get some information I'll post it on the blog.
