The weir was used during 2001, 2002, and 2003 and the remote video recorder was used during 2001 and 2002. The weir was installed by June 2 each year and operated through mid to late July. Video equipment was operated between June 13 and July 26 during 2001 and between June 4 and July 15, 2002. Information on run-timing and age, sex, and length compositions were collected at the weir site.
