This array is located at the terminus of the Dworshak National Hatchery adult fish ladder. The ladder is 321 feet in length and originates in the North Fork Clearwater River. Fish ladder operations are intermittent and coincide with broodstock collection needs. All fish that ascend the ladder are ponded and held until they are inventoried and sorted. Wild fish are returned to the river, hatchery fish are held until spawning and those fish that are excess to broodstock needs are outplanted. Outplant locations vary with species and time of year.

As a rule May would be the only time our ladder is likely to be closed for the entire month. Pretty much every other month it will be open at sometime. The ladder is opened for minutes to days, depending on run strength and hatchery needs. The variability is large across years and I would wager that very few years are similar overall. |
