Why this matters

Floating islands, often called tumbagas or peat rafts, form when vegetation detaches from shorelines and accumulates organic matter. Their sudden appearance in managed reservoirs like Williston Lake can signal shifting water levels, ecological changes, or debris accumulation, impacting local navigation, recreation safety, and watershed monitoring.
