Crayfish were counted, measured (carapace length in mm, CL), sexed, and life stage determined. Number, size and life stage of crayfish per burrow varied within and among months. Burrow excavation yielded ovigerous females in spring and a new cohort of young-of-the-year (YOY) crayfish in June 2005 and 2006. Burrows contained both sexes of adult (≥27 mm CL) and juvenile (
