The
Diversion Structure at Low Water
At low water, this picture
shows the red water level sensor well in the center and the downstream
edge of the main diversion trash rack tower. The new trash curtain
would extend from this diversion structure downstream ot the pier
out of the photo. |

Inlet
Area Looking North
Inlet area showing the
trash rack on the right, the trash barge in the middle, the power
line service drop, and the right hand dam pier on the left of the
photo. The new trash curtain would close off this area to debris,
remanding woody debris to stay in the river.

Upstream
Cross Beams
The west end of the passage
between the gate tower and the trash rack tower. The red column
is a water level well. Note the dark ring on the cement at the normal
water level.

Downstream
Crossbeam in Diversion Structure
The sheet pilings on
the left are the west end of the parking lot. The redish conctete
covered beams cross between the trash rack tower and the gate tower.
There is ample passage for water under these cross beams. The space
is trapazoidal roughly 15 feet wide by an average of 6 feet deep.

Parking
Lot Corner
Foot square "I"
beams hold sheet piling for the parking lot. This photo looks almost
straight down on the corner of the parking lot captuing a corner
of the guard rail.

Trash
Conveyer
Most trash ends up on
this conveyer which dumps it into a truck for removal.

Diversion
Structure at Very Low Water
Normal water lever is
about 3 feet higher than this photo as can be seen by the "tidal"
ring. This shows the top of the passage between the trash rack tower
and the gate tower on the left.

Trash
Removal Parking Area
This is the lower parking
area, used almost exclusively by the operators when removing trash
from the area.

The Upstream
Gap Looking Downstream at the Dam
Looking downstream along
the parking lot guard rail and sheet piling toward the dam inlet
area. The inlet grizzly is just to the right of the rounded pier
- in the center of this photo.

The parking
lot / trash rack tower water gap at low water.
The front of the shadow
on the water is the area that will have a loose curtain to keep
trash out of the area downstream of the diversion. The parking lot
is on the right behind the guard rails, and the upstream end of
the PG&E trash rack is shown on the left. The horizonal gap
at water level between the trash rack tower and the parking lot
sheet piling retention I beams is about 10 feet.

Inlet
Area from Road
This shows the power
line in the center. The gap between the diversion structure on the
left and the rounded dam pier on the right will have a hanging trash
curtain to assist in trash management. This picture shows the little
trash that is accumulated over many months.

Entire
Diversion Area from Across the River
This view shows the parking
lot of the right, the diversion trash rack, the distribution line
coming down the hill, the trash barge, and the log boom. The phone
line conduits coming down the hill is visible but partially buried
in the brush at the left behind the lamp post.
