A study recently published by the National Academy of Sciences shows a poor outlook for the future of Adirondack brook trout populations in lakes. According to the Adirondack Daily Enterprise, the study learned that in 2023, only an estimated 4.8% of 1,468 Adirondack lakes contain suitable habitat for trout. That suitability is a significant decrease from the 1980s, when 23.4% of those lakes contained suitable habitat.
