A commercially produced floating island was installed in the river otter enclosure at Zoo Montana in 2007. In 2009 and the beginning of 2010, a few larger islands were launched to provide nesting habitat for Caspian tern colonies. The largest of the islands, at a record-setting , was launched into the water at Sheepy Lake. These islands are a collaboration between the United States Army Corps of Engineers, Oregon State University, and Floating Islands West, a Floating Island International license holder.
