If your only interested in a month of data and not concerned about a long-term deployment, I would just put the Mayfly/hardware/batteries in a nice IP 67 or 68 enclosure with a voltaic solar panel and strap it to a something like a spare buoy. The picture attached isn’t pretty but would probably work for long-term deployment in small inland lakes.
