Randa and I have been working on a program to present when we are roving at the Visitor Center. We are calling it "The Big Birds of Bonneville" Here are some of the photos that we have gathered and printed for display. Do you know these birds?

Bonneville Map
Here is a map of our work location. Our trailer is parked at the west end of Robins Island about where the "I" is in Island. Most of the time is spent at the Bradford Island Visitor Center. We also
work at the Washington Shore Visitor Complex,( known here as the VOB, the Visitor Orientation Building. To get there we are able to drive across the dam to get there. We can do that because we have special name tags that have built in chips that open gates.Starting this week the Navigation Lock Visitor Area opened during the afternoons. Visitors can stop by to view ships using the lock. Our duty time there will be talking to folks who stop by watch ships rise up 60 ft.

Barges
Today we had training at the Navigation Lock. Huge barges travel up and down the Columbia carrying freight (mostly grain ) down river to ... [ I need to ask about the destination ]
They pass right by our rig. The lock channel is about 100 feet from us. Without the many trees, we would have a fabulous view of passing traffic. As it is, there are many breaks in the greenery to watch the progress.
One of the units that pass here almost every evening is a barge carrying juvenile fish . The dam has several programs to benefit the salmon run. The fish ladders direct the adults around the dams and upstream.
The juvenile salmon are the focus of many changes.
The turbines that generate electricity have been redesigned to minimize fish deaths passing through them. (The survival rate passing through the dam is 95 - 98%.)
The way water goes through the spillways has been modified to make that trip less stressful for the young fish going out to sea.
There is now a diversion stream of water that pipes water and fish around the dam in a 2 mile long tube and back into the river. In addition, a a huge sprinkler system sprays water in the air at the output area to keep birds, (gulls) from gobbling up the fish as they re-enter the river.
Then there is the barge. It goes by our site about 7 o'clock. It travels down several miles to about Beacon Rock where the load of juveniles are released after dark to try to fool the sea lions.
Then there are the sea lions. California Sea Lions and Stellar Sea Lions. Guess what sea lions like to eat? You guessed it, Salmon.
Fishermen say, "Kill Em !"
Ecologists say, " You can't Kill them, They're endangered !"
Big controversy. Big!!!! So what's being done? You already know what the dam and the Corps of Engineers are doing. The USDA and the Department of Fish and Wildlife of Oregon and Washington are trying to help. There are folks trapping sea lions to determine and branding them to see if there are certain ones that are the real "bad guys". Also, get this" there are people hired by the USDA to shoot "Flash Bangs" near sea lions to "discourage" them from hanging out in the area of the dam. I talked to one the guys and he was a happy guy. " I get free camping, work 40 hours a week on my schedule and get to shoot a gun legally. He was provided a single shot 12 gauge with special shells. His job is to drive around the site and watch for the critters. When he sees them he puts a couple of rounds of these special shells into the air or water nearby to harass them into moving elsewhere. Not sure how well the program works but at least they are trying. When he leaves here next month he will go to the John Day Dam and shoot gulls who eat the little salmon.
The money spent on salmon restoration is enormous. I have heard that the budget for the harassment program is about $1,000,000 a year. Yipes. I had no idea of the enormity of the problem.

This is the Juvenile barge coming back from dropping off fish.
Here it's coming up along side our site

This is a photo taken of the fish viewing window at one of the powerhouses. It is one of the most visited areas of the dam. Folks what to see the fish. These are windows on the fish ladders. I will talk more about them soon.

The Lock
The lock at Bonneville are one of 7 on the Columbia/Snake River navigation channel. Each on is large enough to accommodate 5 barges at the same time. River traffic is an important part of the mission of the Bonneville Lock and Dam. Over 50% of wheat produced for export in the US is shipped on barges coming down the river.
Here is a barge entering the lock at 9pm last night.

But other vessels also use the lock. This morning this river cruise ship passed through. The ship moored at Stevenson, Wa. and the passengers were bussed to the dam for a visit.
Private pleasure boats are able to take advantage of the lock as well for free.
