The R.O.V. was lowered into a vertical intake, took a 90 degree turn at the bottom of the intake, & penetrated 200' of tunnel carved into the native rock to the penstock. It was confirmed there was no blockage & this marked the first viewing of the inside of this tunnel since 1928. 2009: Ward Lake Dam Valve Repair Diversified Diving Service was hired to do a valve repair at the Ward Lake dam.

The barrier net allows the hatchery to control the number of salmon returning to the hatchery.
