The Long Term Resource Monitoring Program (LTRMP), a component of the Environmental Management Program for the Upper Mississippi River System (UMRS), is funded by the U.S. Army Corps of Engineers and administered by the U.S. Geological Survey's Upper Midwest Environmental Sciences Center (Center) in La Crosse, Wisconsin. The LTRMP supports six field stations operated by state agencies in Illinois, Iowa, Minnesota, Missouri, and Wisconsin ( Figure 1) to collect most of the monitoring data. Data on important ecosystem components, including water quality, vegetation, macroinvertebrates, and fish are obtained using standardized operating procedures. Monitoring activities focus primarily on six study areas: Navigation...
Two new localities from Pool 26 of the Mississippi River are reported for the western sand darter (Ammocrypta clara) for Missouri and Illinois. One locality is at River Mile 219.4, Perry Island, St. Charles County, Missouri; the other is at River Mile 235.0 236.0, Hat Island, Calhoun County, Illinois. Specimens were collected at the first locality in one year (1992) out of five years (1989 1993) of sampling and at the second in two years (1989, 1992) out of five. The specimens of this species accounted for 0.4% of all fish collected in 1989, and 0.07% of all fish collected in 1992. All collecting sites had a sand substrate with significant current.
Data from the original General Land Office (GLO) survey (1815) of the 5th Principal Meridian were used to evaluate presettlement vegetation patterns in eastern Missouri and Arkansas. Data were divided into three physiographic sections: Mississippi Alluvial Plain, Ozark Plateau, and Dissected Till Plain. Distances to bearing trees and diameters were used to estimate tree density and to evaluate the relative structure and composition of presettlement vegetation. The Mississippi Alluvial Plain was the most densely timbered physiographic section. White oak (Quercus alba), black oak (Q. velutina), sweet gum (Liquidambar styraciflua), and hickory (Carya spp.) had high importance values. Significantly lower tree densities...
This paper examines the characteristics of waves and drawdown generated by barge traffic in inland waterways. The analysis was made on the basis of field data for 77 events collected from several sites along the Illinois and Mississippi Rivers. To illustrate the range of variations in waves and drawdown in the inland waterways, three case studies were selected. A synchronized comparison between waves and drawdown, local velocity, and turbidity level at the nearshore zone is also presented.
Fish, water quality and vegetation data are collected each year through the Upper Mississippi River Restoration‐ Environmental Management Program‐ Long Term Resource Monitoring Program (LTRMP). A complete description of the program can be found at: http://www.umesc.usgs.gov/ltrmp.html. Personnel from the Wisconsin Department of Natural Resources collect data in Navigation Pool 8, one of 6 study reaches included in the program. Data have been collected under a stratified random framework for fish and water quality since 1993 and for vegetation since 1998. This report summarizes the 2012 dataset.
The timing, amplitude, frequency, and duration of water level fluctuations greatly affect river life. On regulated rivers like the Mississippi, water level and current velocity fluctuations are caused by natural hydrologic events that change river discharge and by operation of water control structures. Opportunities exist for modifying river regulation to improve habitat conditions and productivity of the river ecosystem. Modifications to the present system of river regulation must be made within constraints imposed by the hydrology of the basin, engineering characteristics of the system, and within legal and administrative requirements. Hydrologic, engineering, legal, and administrative constraints on river regulation...
This study undertook the identification of constraints on a one foot pool raise at Mississippi River Lock and Dam 18. Pool 18 is approximately 26.5 miles long with a thalweg gradient of 0.28 foot per mile. A pool raise, as measured at the dam, would have variable spatial effect depending on main stem and tributary discharge which creates a sloping water surface at all but extreme low flow conditions. At low or no flow conditions, a one foot pool raise at the dam would flood shoreline vegetation throughout the pool. At the most probable flow the fall migration period, a one foot pool raise could flood approximately 300 acres of low elevation and shoreline vegetation in the lower 16 miles of the pool. Constraints...
Distribution and frequency of submersed aquatic vegetation in the Upper Mississippi River System are monitored as part of the Long Term Resource Monitoring Program. This report summarizes results of sampling aquatic vegetation along fixed transects in Navigation Pools 4, 8, 13, and 26 in the Upper Mississippi River and La Grange Pool in the Illinois River in 1996. Plants were sampled at regular intervals along fixed transects using a modified rake technique. Sampling was conducted twice during the growing season (spring and summer). Twenty-four submersed and rooted floating-leaved species were found. Most species were found in Pools 4, 8, and 13. Pool 26 had the fewest (3) number of species and Pool 4 had the greatest...
Continuous dissolved oxygen and temperature readings were taken along with early morning readings in Big Lake Bay, Finger Lakes, and the Pool 8 Islands area to document and provide preproject data on each location. Similar readings were taken in Lake Onalaska to provide postproject data. Sampling took place from August 13 through September 5, 1990. All sites displayed daily fluctuations in dissolved oxygen and water temperature. Daily variation in dissolved oxygen and temperature relate directly to the daily weather conditions. Overcast, cloudy days have less fluctuation in dissolved oxygen and temperature than do sunny days. Density of aquatic vegetation and lake size also influenced the extent of variability in...
Resource Trend Analysis water quality and sediment sampling in Upper Mississippi River Pool 13, was initiated in August 1988 as a part of the Long Term Resource Monitoring Program. Mississippi Monitoring Station personnel began water quality sampling on Pool 13 the first week of August using equipment and techniques based on the Procedures Manual for the Long Term Resource Monitoring Program. Over 2600 water quality measurements were made under the Resource Trend Analysis component of the Long Term Resource Monitoring Program on Pool 13 during the sampling period, August 1, 1988 through October 31, 1988. Dissolved oxygen increased throughout the sampling period. Means at channel habitats were slightly higher than...
Consistent, friendly, and professional customer service is not only a reasonable expectation but an absolute requirement if contemporary information systems support organizations are to accomplish assigned missions. Most automation support offices are comprised of a multi- disciplinary array of professionals who, for the most part, have a common goal: to do the best job possible (the good). Lack of understanding of customer needs, poor communication, or sloppy interpersonal skills by automation support professionals can result in the perception that such is not the case (the bad). In some cases, individuals providing customer service are highly enamored of their own position and/or responsibilities and may give...
Vessel traffic and river environment descriptor variables have been listed and the magnitudes of their ranges defined. Target physical variables were selected on the basis of their likelihood of having biological effects. The total number of variables is 34, not including several basic quantities like water density and viscosity, which were introduced in a discussion of dimensional analysis. Dimensional analysis was used as a rational approach to a conceptual model of the physical impacts of navigation on constructed waterways. Eight parameters characterizing the physical effects of tow passages were discussed in detail. Because of its complexity, special attention was given the effects of the propulsion system....
This metadata catalog was developed to provide potential users of Environmental Management Technical Center (EMTC) spatial data with information about available spatial data and how these data files were developed. However, since new data files are continually in progress, this catalog may not contain information about some of the more recently developed spatial data files. Catalog updates will be provided on a quarterly basis. The data listed in this manual primarily cover the Long Term Resource Monitoring Program study area. The study area is contained within the floodplain of the Upper Mississippi River System (UMRS), including the Illinois River and navigable tributaries between Minneapolis, Minnesota, and Cairo,...
The 1991 river boating study focused on the Twin Cities metropolitan area. It encompassed the Mississippi River from Coon Rapids Dam to Dam 5, and the commercially navigable reaches of the lower St. Croix and Minnesota River. The study was conducted from July 3 to September 2. The primary goal of the study was to collect the information needed to construct a mathematical origin-destination model of boat trips in the study area and, ultimately, to build such as model. The model would permit the manipulation of boat access development (locations and sizes of ramps and marinas) and would estimate the resultant impact of these manipulations on summer boating patterns on different reaches of the rivers. A similar model...
Construction of locks and dams along the Illinois River, especially in the reach extending from Grafton to the Lake DePue area, has created a large number of backwater areas within the main floodplains of the river. These backwater areas are called backwater lakes, and they are subject to natural variations in water depths and sediment deposition. Moreover, over the last 100 years or so all the river basins in Illinois have been subjected to intense human activities and alterations. As a result of these natural and human interventions, the Illinois River valley has experienced a tremendous amount of sediment deposition in recent years. Many of the 53 or so backwater lakes along this river have lost 30% to 100% of...
Field investigations were undertaken to document physical and water quality impacts associated with recreational boating activities in upper Pool 4 of the Upper Mississippi River System. The study documented high erosion rates irrespective of geomorphic position in the Main Channel and development of a diurnal turbidity plume in the littoral zone. A comparison of commercial tow, wind, and recreational boat surface wave characteristics, along with other observations and the use of a control channel provided the perspective necessary to determine relative responsibility for the observed impacts. Recreational boating was found to be the contributing influence most responsible for the high shoreline erosion rates documented...
The Upper Midwest Environmental Sciences Center of the U.S. Geological Survey and its state partners monitor the aquatic vegetation as well as fish, water quality, and macroinvertebrates in the Upper Mississippi River System. The objective is to accumulate incremental data on aquatic vegetation over a long term using a standardized protocol across the system. The data provide basic information on the vegetation growth within pools for use by resource managers and planners as well as the public for the protection and enhancement of the Upper Mississippi River System. This report summarizes the annual stratified random sampling monitoring results of aquatic vegetation in the Upper Mississippi River System.

This report is the first of a series of reports on the status and trends of the nation's plants, animals, and ecosystems. It represents an effort to bridge the gap between scientists and resource managers, policy makers, and the general public. Usually, scientists tend to write for scientific journals and communicate with other scientists: this report attempts to collect a great variety of scientific data and interpret it for the nonscientist while maintaining the full credibility of the data. Published by U.S. Department of the Interior, in 1995.
