|Flying down Henderson Creek near dam #18|
Eagle watching is a popular enough pastime at these locks that the Corps has installed observation platforms at each lock. These platforms generally provide the best access for viewing, because they get you up above the lock so that you can see the open water below the dam. The one exception is lock & dam 14 at Pleasant Valley, IA (just north of I-80 and Davenport). Here, there's a much longer viewing deck right at the western river bank in a location that doesn't have to look over top of the lock. Number 14 provides the best access for shooting eagles, assuming there are any eagles there to be photographed. If you want to get a shot of an eagle plucking a fish from the water, #14 is where to go. However, because it's one of the more urban dams, the numbers are generally lower there than at other dams.

It was a fun trip with my daughter, but it was a lot of driving for not very much shooting. I think it would have been better if we'd had more eagles at dam 14. Next time, we'll allow time for a few side trips, such as the frozen waterfalls of Starved Rock State Park or the American Gothic house.
When choosing your gear, remember that the Mississippi River can be half a mile wide below the dams, and the eagles might be on the far side of it. You're definitely going to need a long lens to get any decent shots.

My 70-200mm (or 280mm with the teleconverter) lens certainly wasn't long enough to reach across the river, so I rented a Canon 100-400mm f/5.6 L lens for the trip. 400mm with the 1.6x crop sensor was still frequently not long enough. Adding my 1.4x teleconverter helped, but that put me at f/8, where my Canon 7D was unable to autofocus reliably except in excellent light (meaning I was back to manual focus). I shot with the teleconverter about half the time -- only when the birds were so far off that the cropping at 400mm would have been excessive. Next time around, I'll seriously consider renting either a longer lens or a faster one that can still autofocus with a teleconverter. Although I took the 70-200 with me, I never used it. I think the widest shot I took (not including super-wide environmental shots) was about 200mm, and that was on a single eagle that flew overhead very near us.

When shooting birds in flight, it really helps to have a camera with lots of autofocus points. The standard 9-point AF pattern on low-end Canon cameras (like the 50D) really sucks, because if your center focus point drifts off the bird, the AF will hunt all over trying to focus on the sky. The Canon 7D's 19-point AF pattern is much better, as the points are more densely packed and make it easier to keep at least one point on the bird. I can only imagine how nice a 60-point pro body would be in this environment.

As I mentioned before, there weren't many eagles at dam #14 near Le Claire / Pleasant Valley. We saw maybe ten of them, but most were too far off to get interesting shots. The one exception was an adult eagle that camped out in a tree right above the parking lot. At one point, he flew out, grabbed a fish, and ate it in that tree for us. I got a number of fun shots of him, but that was literally the only interesting thing to shoot in the hour we were there, which was a disappointment. Most of the best eagle shots I've seen were taken at #14, so I had high hopes for this spot. Maybe next time...

We spent the next morning at dam #18 north of Burlington, IA. The lock's observation deck is closed for construction until March, but the Henderson Creek Rec Area that surrounds the lock has a boat dock 100 yards downstream, so we parked there & walked up the shore until the lock itself started obscuring our view. There were easily 1000 birds visible (confirming the Corps' count). The open patch of water was mostly on the far 2/3 of the river, so we were too far away to get any shots of the birds pulling up fish. There were lots of eagles flying directly overhead, though, so we did get plenty of close in-flight shots. If the observation deck had been open, the angles and distance would have been better for fishing shots. This video illustrates our shooting location on the bank below lock #14:
After an hour or so on the bank, we left the river and went back to the bridge where the lock's entry road passes over Henderson Creek. It's maybe a quarter mile east of the river. There were dozens of eagles roosting in the trees and playing on the frozen creek, and they were closer than what we saw on the river. I managed to sneak up the side of the creek and get a few of my best shots of the eagles that didn't mind me getting close. In retrospect, this was probably a bad idea, as it did scare off most of the birds. This video shows the view from the Henderson Creek bridge:
All in all, it was a great way to spend a weekend with my daughter, but I probably wouldn't do it every year unless the conditions were great.
