Looking towards the river and pumphouse (east). On the backside of the pumphouse is where most of the work to remove the sediment will happen. Note the work space and drivable space available in this photo.

Slight turn the the south, showing edge of diesel tanks and a bit more of the paved area. The hoses that will carry the sediment out of the water will run across this paved pad from the white building along the ground where the escavator is parked and end just behind the diesel tank in a barracade area.

Slight shift to the right to show the north side of the pumphouse. There is a paved walkway that allows access to the river from the right side. This is helpful when pumping out the sediment in front of the intake area and the area directly north of the gates that block large debris from entering (grousers).

Standing at the northwest side of the pumphouse looking south. Containment area for the sediment is just behind the tan fuel tanks.

Looking east out towards the river, standing on the northside of the pumphouse. The paved walkway goes out past the overhead I beams and allows a different access point for deploying pumps and hoses.

Standing at the end of the paved walkway that overlooks the river and backside of the pumphouse.

Looking west at the hatchery.

Turning south to look at the backside of the pumphouse where the intake for the hatchery is located.

The “V” like concrete intake just in front of the railings is where most of the work will occur for this project.

Photo looking down into the main sediment deposit zone. On the backside of the pumphouse. The two intake gates can be seen in the to right of the photo. The water entering this area from our ponds (top left of the photo) will be turned off during this project. A wooden float platform with space to hold the water pump will be deployed into this basin as well.

Looking north from the end of the walkway. This area in the river gets cleaned as well. We deploy a float and suck the sediment close to the spot where this photo was taken.

Overlooking the railing in the above photo down into the river area where we will remove sediment from the outside of the intake area. Just beyond the metal grating (grousers).

Metal grating helps block large debris from entering the hatchery. This area is pumped out as well and used to secure the float that houses the pumpp for part of the project.

Standing on the south side of the pumphouse looking northeast. The river is just beyond the concrete blocks. Roll up door and man door provide access to the inside of the pumphouse where the chambers are that house the pumps and screens. These chambers need to be pumped out as well as the outside in river area of the intake.

Looking into the intake basin from the south side of the pumphouse. Note previous intake photos were taken from the concrete walkway in the top section of this photo. Also in this picture are the metal barrier gates (grousers) that hold back large woody debris from entering the hatchery water system.

This chamber/basin area in the photo is where most of the work will happen.

Photo showing metal eyelets along the east concrete wall. These eyelets are used to string up the discharge hose that will be connected to a pump, which is deployed on a wooden float inside this area.

Inside the pumphouse there are 4 vaults with attached ladders that allows access to the area under the pumphouse. 2 chambers are before the water screens and 2 are after (this photo is 1 vault after the screens). These are confined space areas and will need appropriate PPE).

North side pumphouse vault 1 (pre-pump)

Fixed ladder access.

Southside vault (pre-pump)

Another northside picture of vault. Vaults on the otherside of the water screens have the same size entrance, they are just located on the east side of the building. These ones in the photos are on the west side of the building. There are 4 total that need to be accessed.

Sediment that is removed is pumped into this barracade area behind the tan fuel tanks. This holding area allows the sediment to build up, dewater, and essentially be scooped out and moved to its final deposit location.

Corral for sediment.

Looking northeast towards the pumphouse from the sediment containment area. Hoses will be run to the barracade for discharge.
