Crediting Language
These data are a product of the U.S. Army Corps of Engineers' Upper Mississippi
River Restoration Program (UMRR) Long Term Resource Monitoring (LTRM) element
implemented by the U.S. Geological Survey in collaboration with the five
Upper Mississippi River System (UMRS) states of Illinois, Iowa, Minnesota,
Missouri, and Wisconsin. The U.S. Army Corps of Engineers (Corps)
provides guidance and has overall program responsibility.
-------------------------------------------------------------------------------
MACROINVERTEBRATE TREND ANALYSIS DATA
Annual macroinvertebrate monitoring on the Upper Mississippi River System
(UMRS) was implemented in 1992 under the Long Term Resource Monitoring Program
(LTRMP). Mayflies (Ephemeridae), fingernail clams (Sphaeriidae), and the
exotic Corbicula species were selected for monitoring. Midges (Chironomidae)
were added to the monitoring scheme in 1993, with the addition of zebra
mussels (Dreissena polymorpha) in 1995. Mayflies, fingernail clams, and
midges, found in the soft-sediment substrate, were chosen because they play an
important ecological role in the UMRS. The exotic Corbicula species and zebra
mussel were chosen for sampling because of possible detrimental impacts they
may have on the economy and biology of the UMRS.
-------------------------------------------------------------------------------
FOREWARD
Use of LTRMP Trend Data for Macroinvertebrate Monitoring
The sampling design for macroinvertebrates is relatively simple; however, all
potential users of these data are strongly encouraged to read and understand
the Macroinvertebrate Monitoring section of the LTRMP Procedures Manual (Thiel
and Sauer 1999), which describes current procedures, before undertaking any
analysis or interpretation of data. This document is accessible by request

SUMMARY
LTRMP Macroinvertebrate Sampling Design
The LTRMP conducts annual monitoring of macroinvertebrates in six study areas
of the Upper Mississippi River System: Navigation Pools 4, 8, 13 and
26, and an unimpounded reach near Cape Girardeau, Missouri, on the Upper
Mississippi River; and La Grange Pool on the Illinois River. The LTRMP
conducts highly standardized macroinvertebrate sampling in main channel
border, side channel, contiguous (to the main channel or side channels)
backwater, and impounded aquatic areas in each study areas. Sampling is
conducted using a standard Ponar grab dredge (Wildlife Supply Company,
Saginaw, Michigan).
Sampling is based on a stratified random design and is conducted at
approximately 125 sites in each study reach. The aquatic areas serve a
strata. Sites include a few locations where benthic samples were collected
historically. Each field station is required to conduct macroinvertebrate
sampling at the same time each year, prior to mayfly emergence.
