SUMMARY: Staff requests authorization to spend not more than $4,000 of FY 2003-2004 Mitigation Program funds to purchase materials to retrofit pool #2 (Tank 2) at the Sleepy Hollow Steelhead Rearing Facility (Facility).
RECOMMENDATION: Authorize the General Manager to expend funds not exceeding $4,000 for the purchase of materials to retrofit Tank 2. The Administrative Committee considered this item on March 10, 2004, and recommended approval on a vote of 3 to 0.
BACKGROUND: There are three large fish holding tanks at the Facility, two at 22-foot diameter and one with 30-foot diameter. These tanks are intended to hold the larger juvenile fish rescued from the lower valley. Staff has also held large batches of small fish in them at times. The tanks are set-up on a flow-through system, with clean river water continually refreshing the tank. But, due to the large volume of water and relatively flat bottom, disease organisms shed by the fish may remain in the tanks for a long period of time, potentially infecting other fish.
The Department of Fish and Game (DFG) pathologists have recommended retrofiting the tanks to allow the water to flow through more quickly, thus reducing the spread of infection. Staff proposes to modify one of the 22-foot tanks as a pilot project by constructing a spiral concrete wall around the inside of the tank and lining the new channel with HypalonŠ (a nylon reinforced watertight rubber) material. Weirs will be installed at regular intervals to hold the water in pools within the spiral channel.
IMPACTS TO STAFF/RESOURCES: Funds for this project expense are included in the FY 2003-2004 District Budget under Aquatic Resources Fisheries as line item No. 2-4-1D, Retrofit Pool No. 2, $4,000. Approximately 240 hours of staff time will be needed for this project spread between fisheries and river maintenance staff.
