1. Long Term Resource Monitoring Program study areas and locations of field stations.
2. Mean discharge (m3/sec x 1,000) at the St. Paul, Winona, Keokuk, and St. Louis gaging stations, Upper Mississippi River System, 2001.
3. Water elevations (feet above mean sea level) for Pool 4, January–December 2001, Upper Mississippi River System.
4. Water elevations (feet above mean sea level) for Pool 8, January–December 2001, Upper Mississippi River System.
5. Water elevations (feet above mean sea level) for Pool 13, January–December 2001, Upper Mississippi River System.
6. Water elevations (feet above mean sea level) for Pool 26, January–December 2001, Upper Mississippi River System.
7. Water elevations (feet above mean sea level) for the Open River Reach, January–December 2001, Upper Mississippi River System.
8. Water elevations (feet above mean sea level) for La Grange Pool, January–December 2001, Upper Mississippi River System.
9. Land cover/land use (LCU) data for Pool 13, Upper Mississippi River System (UMRS).
10. Electronic data sheet used for field data entry.
11. Dissolved oxygen and snow and ice cover in stratified random sampling of backwaters in Pools 4, 8, and 13 in winter (January-February).
12. Since 1996, chlorophyll a (µg/L) concentrations in Pool 26 in summer stratified random sampling show increasing concentrations and higher variability.
13. Illinois River (upper right) combining with a Mississippi River side channel (lower left) near Grafton, Illinois, in 1997.
14. Annual means of the daily average discharge (cfs) from 1930 to 2001 show that the Long Term Resource Monitoring Program (LTRMP) has monitored one long-term flow cycle (about 11 years).
15.
Monthly transport of nitrate past Pool 14 (Clinton, Iowa) in the floods of 1993 (dashed line) and 2001 (green solid line) as shown by Long Term Resource Monitoring Program data.
16.
Percent frequency of occurrence of submersed aquatic vegetation collected during stratified random sampling.
17. Abundance Index of submersed aquatic vegetation collected during stratified random sampling.
18. Spatial clusters of 14 Upper Mississippi River System (UMRS) navigation pools based on fish community composition (presence or absence data).
19. Spatial clusters of 14 Upper Mississippi River System (UMRS) navigation pools based on fish community structure (ranked abundance data).
20. Multivariate ordination of the 10 gears used to monitor fishes in the Upper Mississippi River System (UMRS) under the Long Term Resource Monitoring Program.
21. Estimated mean mayfly (Ephemeridae; number m-2) by study area, weighted by area of strata from 1993 to 2001, Upper Mississippi River System.
22. Estimated mean fingernail clam (Sphaeriidae; number m-2) by study area, weighted by area of strata from 1993 to 2001, Upper Mississippi River System.
23. Estimated mean midge (Chironomidae; number m-2) by study area, weighted by area of strata from 1993 to 2001, Upper Mississippi River System.
24. The University of Illinois Geographic Modeling Systems Laboratory merged light detection and ranging data from STS, Inc., and bathymetry data from the U.S. Geological Survey Upper Midwest Environmental Sciences Center to produce this seamless image of The Nature Conservancy's Emiquon tract in Illinois.
25. Georeferenced map of sampling locations for freshwater mussels, by sampling method, in Pool 8 of the Upper Mississippi River. Data purchased from Malacological Consultants in 2001.
26. Comparison of fish species caught using Long Term Resource Monitoring Program trawl (gray line) and Missouri trawl (black line) in the Open River Reach of the Mississippi River. Lines represent cumulative number of fish species caught at selected sampling intervals.
27. Length ranges of blue catfish (Ictalurus furcatus), channel catfish (I. punctatus), freshwater drum (Aplodinotus grunniens), and white bass (Morone chrysops) using three trawl types (10.2-m, Missouri, and Long Term Resource Monitoring Program [LTRMP]) in three reaches of the Mississippi River.
28. Diagram of mapped wing dam (dike).
29. Scour hole depths behind wing dams (dike).
30. Interpolated data of approximately 100 waypoints obtained below wing dam (dike) 32.2 on the Middle Mississippi River to create a topographic image of the scour hole.
