Big Bureau Creek
The Big Bureau Creek is a 〔U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed May 26, 2011〕 tributary of the Illinois River in north central Illinois. It rises approximately north of Mendota and flows southwest into Bureau County, turning south at Princeton and then flowing east into the Illinois River floodplain.〔 Among the creek's more notable features is the Red Covered Bridge, built in 1863, which passes over Big Bureau Creek and was once part of the Peoria Galena Trail. The bridge, located just north of Interstate 80, is listed on the National Register of Historic Places.
==Ecology==
Currently, there is an effort underway to maintain this watershed as well to evaluate its current condition with the Big Bureau Creek Watershed Inventory and Evaluation (I&E) begun in 2003 (See the Forward and Acknowledgment section for the year 2003).〔ftp://199.133.90.201/pub/outgoing/Downloads/IL_Big_Bureau_Creek/Big_Bureau_Creek_Watershed_Inventory.pdf〕 Nitrogen levels from surrounding farmland, sedimentation, and low water levels are the main problems to be assessed.
