REMARKS FOR CURRENT YEAR.--Habitat measurements, including physical and geomorphic, were collected as part of the National Water-Quality Assessment program (NAWQA) in the lower Illinois River Basin. The measurements were collected according to Meador and others (1993). Reach A begins 607 ft upstream of the road 450 N bridge (1.95 mi upstream of the gage) and continues upstream for 568 ft. |

The following links list up to five tab-delimited text files containing habitat data collected at several sites. An explanation of column headers in these files can be accessed at this link.
Reach -- General description of the sampled reach.
Geomorphic Channel Unit (GCU) -- Fluvial geomorphic descriptors of channel shape and stream velocity (for example pool, riffle, or run).
Transect -- Channel and bank measurements made along transects (cross sections) within each reach.
Channel features -- Measurements of bars, shelves, and islands at each transect (cross section).
Transect Points -- Channel and substrate measurements and observations at points along a transect (cross section).
