Rice Lake -- Let Nature Do It

The Army Corps of Engineers is proposing a more than $11 million project at the Rice Lake State Fish and Wildlife Area along the Illinois River. I really hope they don't go through with the project.

The project plan includes new river pumps, levees, and water transmission ditches, as well as the planting of 400 acres in trees. In my opinion, planting trees in an area on Duck Island that is currently being farmed is a fine thing to do. However, removing large numbers of trees that eagles use in the winter to roost and in the spring and summer to nest, in order to build levees and drainage ditches and to install large pumps is way too damaging to the environment. The construction would do nearly as much damage, if not more, to parts of this internationally listed migrating bird habitat as it would help.

The corps plans to build 2,500 foot spillway that requires them to remove two feet of soil each foot of the length of the spillway, reducing the height to 10.5 feet. Water levels along this part of the Illinois River regularly top that. The plan requires the corps to remove more than 20 acres of mature trees for the levee and channel construction, which will impact bald eagle roosts as well as osprey nesting sites.

Many of the site's existing problems are due to lack of state funds to maintain current equipment and poor management. How will IDNR provide adequate funds for the additional costs of operating four new pumps, ditch and channel maintenance and levee maintenance, estimated at a cost of almost $50,000 annually? This number far exceeds the funds available over the past years for such maintenance.

The goal for this project is to enhance wetland and aquatic habitats. However, the best estimate by the Corps is a success rate of only 30 % for moist-soil plants production over a 10-year period! This isn't success! And it comes at a steep cost to the existing environment.

Construction disturbance for this project is expected to last at least three years, causing disruption to species and habitat loss.

Write IDNR Director Miller and Illinois Governor Quinn and ask them to stop this project before $11 million is spent for a 30% success rate and acres of trees lost in the process.

Rice Lake on the Rebound Two Weeks Later

Two weeks after the tour with Bill Douglas and Bill Kapitko, I returned to Rice Lake to see how it was doing without flood waters saturating the land.

Someone has marked trees along the road leading to Copperas Landing, presumably to be removed.

Green carpeted the floors where just 2 weeks ago water was standing. Farther out where mudflats were exposed, a flock of pelicans rested.


At the Voorhees Unit, green carpeted the bottomland forest floor. You can see by the high water line on the trees just how deep the water had been in this area for the past several years.


I wanted to take a photo of the field where Decurrent False Aster grew several years ago before the high water inundated the area. I parked at the entrance of the Copperas Creek Walk-in Unit. However, as soon as I rounded the bend, I saw an IDNR truck and realized I was blocking their way. As I walked back to my car, a black contractor's truck stopped. The driver told me I needed to move my car, which I was on my way to do. He said he and his team were surveying the area for the Army Corps of Engineers proposed project to revamp the area. I was intrigued. I parked my car well out of the way, and decided to walk out to the Narrows Dam, which I had visited by boat with Bill Douglas and Bill Kapitko just two weeks ago.

As I walked down the path from the road, I spotted a stray Decurrent False Aster. It is a state threatened species, and I am glad to find even a small sample of it after the years of high water the area has endured.

The water marks on the trees along the path to the Narrows Dam showed how high the water had been before it was released two weeks ago.

The surveyors had parked their vehicles out on the levee leading to Slim Lake, where the Corps of Engineers plan to build a canal from a pumping station that they want to build to replace the existing pumps in returning water to the area in the fall.

I continued walking out to the dam. The canal that I traveled by boat two weeks ago is just as beautiful from the levee road I was walking to the Narrows Dam.

You can clearly see how high the water had been for so long by the lack of leaves on the lower half of the Button Bushes growing between the canal and the levee path.

A Monarch butterfly posed for me on some blooming Smartweed.

A Common Buckeye butterfly spread open his wings on the path.

Large numbers of Great Blue Herons flew along the edge of Hoaxie Ridge. There were 12-15 herons in all.

The path ends at the Narrows Dam. From there I could see former Peoria Mayor Bud Grieves's windmill and the chimney belching water vapor at Duck Creek power plant.


A family of Wood Ducks swam in the canal near the opening to Rice Lake.


A flock of American White Pelicans were gathered far out on the lake.


A few of them flew over my head, but it was hard to get a decent photo since I was using the mono-pod. It kind of went flying up in the air as I attempted to track the birds. It's a good thing no one was around to get wacked!


Spring Lake State Fish & Wildlife Area

I drove the east side of the river on my way back from Pekin. I wanted to see the swans at Spring Lake. The lake was covered with American Lotus and Water Lily pads.
