Mccloud Redband Reintroduction California Trout The trout from above the impassable middle falls of the mccloud river have been genetically isolated for thousands of years and have evolved into their own distinct fish know as mccloud river redband trout. Rescued fish and offspring reared and released to the wild! severe drought and shrinking stream habitat in 2013 and 2014 led to emergency rescues of mccloud river redband trout from headwater streams in the upper mccloud river basin.
