Lake Level Monitor

I'm trying out an idea. I wanted to find a way to measure the lake level in real-time. Here's how it works. I use a range sensor, the kind that measures distance using an acoustic pulse (from Vernier). The sensor is mounted several feet above the lake and pointing down to the water surface. The range measurement to the surface tells you the lake level. I average several readings to try to smooth out the effects of waves.

The lake level is about normal level right now. Shorter readings indicate a rise in the lake level and longer readings a drop in the level. I wrote a gui in microsoft c# that takes the readings, plots a graph and sends it up to the web page server. Well, we'll see how it goes... See for the chart.

High quality ice-out video available

If you don't mind downloading a large file (285MB) you can watch a high quality time-lapse of Sebec Lake ice-out 2010. The video is 4 days long and begins 2 days before ice-out which was on April 3, 2010. VIDEO

Please be patient as it may take a while for the video to begin.
