Installation of floating islands, a community eventThis floating islands project was initiated when Friends of Hicklin Lake asked for floating islands as an alternative to future alum treatments.  Biomatrix Water / Herrera Environmental were selected to provide platforms installation in July 2013.

The installation was a community event made possible with the participation of numerous volunteers.

This report gives a good overview of the maintenance required and the lessons learned following the initial installation.  Water quality monitoring and metals concentration were also measured.
