841:		Title:	Sediment and nutrient monitoring at selected watersheds within the Illinois River Watershed for evaluating the effectiveness of the Illinois River Conservation Reserve Enhancement Program (CREP).
		Volume/Number:	2001
		Issuing Agency:
		Description:	This report documents the progress that has been made to date on the Conservation Reserve Enhancement Program (CREP) monitoring project. The Illinois Department of Natural Resources (IDNR) through the CREP provides support for this project. This monitoring program collects hydrologic, sediment, and nutrient data for selected watersheds within the Illinois River watershed to assist in the evaluation of the effectiveness of the program. The Illinois River CREP is a new initiative by the State of Illinois and the United States Department of Agriculture to implement conservation practices in the Illinois River watershed over a 15-year period that improve water quality and habitat for wildlife. Monitoring programs were established for sediment and nutrients for two pairs of watersheds within the Illinois River basin to collect hydrologic, sediment, and nutrient data during the implementation phase of the project. The two pairs of watersheds are the Court and Haw Creek watersheds (Spoon River basin) and the Panther-Cox Creek watershed (Sangamon River basin). This report details the location, equipment, and installation techniques used at the five monitoring stations and associated raingages that were installed as part of the data collection effort for this project. Samples of the data collection format and frequency are presented and described. Stage, nutrient concentration, and suspended sediment concentrations for data collected through June 2000 are also presented as appendices.

850:		Title:	Streamflow assessment model for the Little Wabash River Watershed : hydrologic analysis
		Volume/Number:	2001
		Issuing Agency:
		Description:	The Illinois Streamflow Assessment Model (ILSAM) is an analytical and information tool developed to predict the frequency of streamflows, and water use impacts on streamflows, for every stream in selected major watersheds in Illinois. The current version of ILSAM was developed to operate on a personal computer having a Microsoft Windows 95/98/2000/NT operating system. The model user can obtain streamflow frequency estimates for any location in the watershed by identifying the desired stream and location. The ILSAM has been developed for use with streams in five such watersheds: the Sangamon, Fox, Kaskaskia, Kankakee, and Little Wabash River. This report includes a description of the steps used to develop ILSAM for application to the Little Wabash River watershed, along with a description of the physical characteristics of the watershed, its surface water hydrology, and the factors that influence streamflow variability. The Little Wabash River watershed is located in the southeastern portion of Illinois and has a total area of approximately 3238 square miles. The river and its major tributaries provide the source of water supply for all of the major communities in the watershed, either through direct withdrawals from the river or from the storage of water in impounding reservoirs. Many of these communities were forced to undertake emergency measures to sustain their water supply from these sources during the major droughts of the early- and mid-1900s. Thus, an understanding of the frequency of low flows and drought flows is critical for assessing surface water availability and yields for these communities. Streamflow frequency predictions produced by the model are also useful for evaluating instream flow levels for the protection of aquatic habitat, providing streamflow estimates for water quality analyses and regulations, and classifying Illinois streams by their hydrologic character for use in watershed management. The hydrologic analyses used to develop the model include evaluating the flow frequency from all streamgage records in the Little Wabash River region, evaluating impacts to flow quantity from dams, water supply, and treated wastewaters, and developing regional equations to estimate flows at ungaged sites throughout the watershed. All streamflow frequency estimates produced by the model are representative of the long-term expected flow conditions of streams, reflecting hydrologic conditions over a base period of nearly 50 years (1952-1999).

851:		Title:	Operation of rain gauge and groundwater monitoring networks for the Imperial Valley Water Authority. Year Eight : September 1999-August 2000.
		Volume/Number:	2001
		Issuing Agency:
		Description:	The Illinois State Water Survey (ISWS), under contract to the Imperial Valley Water Authority (IVWA), has operated a network of rain gauges in Mason and Tazewell Counties since August 1992. The ISWS also established a network of groundwater observation wells in the Mason-Tazewell area in 1994. These networks are located in the most heavily irrigated region of the state. The region's major source of water for irrigation, municipal, and domestic water supplies is groundwater pumped from thick sand-and-gravel deposits associated with the confluence of two major ancient river valleys, the Mississippi and the Mahomet-Teays. Relatively recent extreme weather events (e.g., the drought of 1988 and the great flood of 1993) resulted in large fluctuations in groundwater levels in the Imperial Valley area. The purpose of the rain gauge network and the groundwater observation well network is to collect long-term data to determine the rate of groundwater drawdown in dry periods and during the growing season, and the rate at which the aquifer recharges. This report presents data accumulated from the rain gauge and observation well networks since their inception through August 2000. Precipitation is recorded continuously at 20 rain gauges for each storm that traverses the Imperial Valley. Groundwater levels at the 13 observation wells are measured the first of each month. The database from these networks consists of eight years of precipitation data and six years of groundwater observations. At the beginning of groundwater observations in late 1994, the water levels were at their highest in the six years of observation. These high groundwater levels were the result of the very wet 1992-1995 period when annual precipitation was above the 30-year normals at both Havana and Mason City. From September 1995-August 1997, precipitation in the region was well below the 30-year normal followed by the 1997-1998 and 1998-1999 observation years with rainfall totals that were slightly above and slightly below normal, respectively. Groundwater levels in the observation wells reflected the multi-year rainfall patterns, showing a general downward trend during the dry years, a recovery in the wet 1997-1998 year, and a leveling off in 1998-1999. Precipitation in the region during observation year 1999-2000 was well below normal, mirroring the quite low totals observed during the dry years of 1995-1997. In response, groundwater levels fell to levels similar to those experienced in 1996-1997. Analysis indicates that groundwater levels are affected by both the precipitation in the Imperial Valley area and, for wells close to the Illinois River, by river stage. Generally, water levels in wells follow antecedent precipitation and Illinois River stage by one to two months, i.e., June groundwater levels are most highly correlated with the Illinois River stage or precipitation that occurs in April or May. The analyses conducted indicate the need for continued operation of both networks due to inconsistencies associated with groundwater levels, precipitation, and the Illinois River stage. For instance, although observation well number 2 (MTOW-2) is located near the center of Mason County, well away from the Illinois River, it has an equal correlation with the Illinois River stage and area precipitation. Additional data collection and analyses are needed to determine the reasons for this and other data disparities.

852:		Title:	Management strategies for flood protection in the Lower Illinois River, Phase II: real-time simulation of flooding with UNET model.
		Volume/Number:	2001
		Issuing Agency:
		Description:	This report documents the structure and the use of a windows-based interface developed by the Illinois State Water Survey for the Office of Water Resources, Illinois Department of Natural Resources. The current version of the interface program is able to download historic, real-time, and forecasted stage and flow data from the U.S. Geological Survey, U.S. Army Corps of Engineers, and the National Weather Service websites interactively. These data are used to update existing Data Storage System (DSS) database or to create new ones; to run the UNET model for historic, design, real-time, and forecasted flood events in the Lower Illinois River; and to post-process model outputs from DSS files in tabular and graphical formats.. This interface program uses the original UNET generic geometry and boundary condition files to maintain the same level of accuracy as the UNET model, but it also allows the user to change some of the parameters, such as, the simulation time interval, time windows, and numerical Corant number, and etc., in the BC file. The real-time simulation of a flood event simulates the flood stage profiles using forecasted stage and real-time flow data downloaded from related websites. With the primary focus on simulations of levee failures, the interface program lets the users modify parameters to simulate simple levee failures through the simple spillway approach for two types of complicated embankment failures, overtopping and piping. A new simulation can be performed using the modified levee information. The change of water surface elevation induced by modifying the levees can be compared with another simulation graphically and also in table format. Stage profiles from all the simulations can be plotted together with the levee heights on both sides of the channel along the Lower Illinois River to provide a visual view of the locations of overtopping. Overtopping locations and magnitudes will be tabulated should they occur.

853:		Title:	Benchmark sedimentation survey of the lower Cache River wetlands.
		Volume/Number:	2001
		Issuing Agency:
		Description:	The Cache River located in the southernmost part of Illinois flows through an area containing the Cache River Wetlands. These unique and important wetlands were designated as a Ramsar Site in 1996. Drainage activities divided the Cache River in half in the early 1900s, effectively separating the river into the Upper and Lower Cache Rivers. The Lower Cache River contains a remnant of a vast wetland system called the Lower Cache River State Natural Area (LCRSNA), commonly referred to as Buttonland Swamp. Sediment inflow from several tributary streams has an impact on the wetland. Previous research has determined that 217,000 tons of sediment were deposited in Buttonland Swamp between 1986 and 1988. The wetlands of the Lower Cache River have been targeted for preservation and restoration by state, federal, and private environmental organizations. A program to monitor the sediment deposition rate within the wetland area at regular intervals would be useful in evaluating and guiding preservation and restoration efforts. This project established a benchmark measure of the deposition rates and cross-sectional profiles at selected locations in the LCRSNA wetland.

854:		Title:	Watershed monitoring for the Lake Decatur Watershed, 1999-2000.
		Volume/Number:	2002
		Issuing Agency:
		Description:	Lake Decatur is the water supply reservoir for the City of Decatur. The reservoir was created in 1922 by constructing a dam to impound the flow of the Sangamon River. The dam was modified in 1956 to increase the maximum capacity of the lake to 28,000 acre-feet. The drainage area of the Sangamon River upstream of Decatur is 925 square miles and includes portions of seven counties in east-central Illinois. Lake Decatur has high concentrations of total dissolved solids and nitrates, and nitrate-N concentrations have been exceeding drinking water standards in recent years. This has created a serious situation for the drinking water supply of the City of Decatur, since nitrate-nitrogen (N) cannot be removed from finished drinking water through regular water purification processes. Nitrate-N concentrations in Lake Decatur have exceeded the Illinois Environmental Protection Agency (IEPA) drinking water standard of 10 milligrams per liter (mg/l) on occasions each year for the period between 1970 and 2000, except from 1993 to 1995. Since 1993, the Illinois State Water Survey has been monitoring the Lake Decatur watershed for trends in nitrate-N concentrations and loads and to identify any significant changes in the watershed. The purpose of the monitoring is to collect reliable hydrologic and water quality data throughout the watershed for use by city planners and resource managers to develop watershed management alternatives based on scientific data. This report presents the annual data for all seven years of monitoring (May 1993-April 2000) and monthly data for Year 7 of monitoring (May 1999-April 2000). Based on the seven years of data, it can be concluded that the unit of nitrate-N loads are relatively uniform over the entire watershed but tend to be slightly higher at the tributary streams in the upper Sangamon River watershed than at the Sangamon River stations closer to the lake. Nitrate-N loads vary with concentrations and streamflow and were the lowest in Year 7 because of the low streamflows during that year. Flow-weighted nitrate-N concentrations have been increasing during the study period at the Monticello station. The highest nitrate-N concentrations during the monitoring period were observed in years 6 and 7.

856:		Title:	Effects of riparian tree management on flood conveyance study of Manning's Roughness in vegetated floodplains with an application on the Embarras River in Illinois
		Volume/Number:	2002
		Issuing Agency:
		Description:	Riparian forests have been proposed by the Technical Advisory Subcommittee of the Upper Embarras River Basin Commission in its alternatives for mitigating flood damages in the Village of Villa Grove and nearby farmlands. In order to evaluate potential reduction in flood stages in Villa Grove, methods for accounting for flow resistances induced by the riparian forests are needed in the hydraulic model for the Upper Embarras River. This project has been designed to better apply the available knowledge in practical field applications, particularly, how to evaluate the vegetal roughness in terms of Manning's andlt;EMandgt;nandlt;/EMandgt; coefficient for specified planting scenarios. Approaches presented in this report are literature review on Manning's roughness with emphasis on vegetative roughness, and evaluation and selection of methods for computing vegetative roughness due to riparian forests. The Petryk and Bosmajian (1975) method was selected for evaluating Manning's andlt;EMandgt;nandlt;/EMandgt; for mature trees because parameters could be reasonably obtained with available general field information. Using this approach, effects of riparian forest on floods were evaluated with the scenarios that the two-year floodplain has two densities of trees. The study reach was the channel between Villa Grove and Camargo. Also investigated were the options of having uniform tree density for the whole reach or half of the reach. An interface has been developed for implementing the computed andlt;EMandgt;nandlt;/EMandgt; values to a HEC-RAS hydraulic model, and capacity curves were developed to illustrate the effects on flood conveyance among these scenarios. The capacity curves thoroughly included possible boundary conditions and were presented in simple nomographs that relate discharge and downstream elevations to a specified flood elevation in Villa Grove. Therefore it was easier to evaluate the resulting effects of different alternatives.

857:		Title:	Sediment management alternatives for the Fox Chain of Lakes along the Fox River in Illinois
		Volume/Number:	2002
		Issuing Agency:
		Description:	The Fox Chain of Lakes is a series of interconnected glacial lakes that are essentially located along the main stem of the Fox River. Originating in Wisconsin, the Fox River flows through northern Illinois before becoming a major tributary of the Illinois River. About 75 percent of the Fox River above the lowest section of the Fox Chain of Lakes lies in Wisconsin. The drainage area above the lowest point of the chain is about 1,184 square miles. The Fox Chain of Lakes has a surface area of more than 6,000 acres. Over the years, significant land-use changes have occurred on this watershed. These changes and the geographical location of the Fox River have resulted in extensive sediment deposition within these lakes. This is especially true for those lakes in the direct path of the Fox River. For example, Grass Lake and Nippersink Lake have lost most of their capacities to sediment deposition. The average depth of Grass Lake in 1975 was 2.7 feet, and the sediment is extremely soft. Within the present research activity, the original research conducted in 1974-1975 by the authors is being examined along with additional data collected by others within the last 25 years. These initial analyses indicated that both in-lake and off-lake sediment management techniques must be implemented to increase water depths within the lakes and decrease sediment loads. Among the in-lake management alternatives that should be considered are dredging and disposing of sediment outside the lake, discharging hydraulically dredged sediment into geotubes or some other type of containment facility within the lake, and creating artificial islands within the lake with dredged sediments. The watershed-based sediment management alternatives could include implementation of best management practices on the watershed, flow and sediment retention basins, side channel sediment traps, sediment management within the stream channel, and the implementation of a systemwide sediment management alternative.

858:		Title:	Embarras River watershed digital floodplain mapping, Champaign County, Illinois
		Volume/Number:	2002
		Issuing Agency:
		Description:	The project objective was to assimilate the best available data to prepare digital maps of critical riparian corridors and areas at risk of flooding for the upper Embarras River, East Branch Embarras River, and Black Slough in Champaign County. Hydrologic, hydraulic, and digital data defining streams and floodplains were reconciled with digital orthophotos of the Embarras watershed. Using orthophotos as base maps, digital data sets were prepared of streams and rivers and floodplain boundaries expected for a flood having a one percent chance of occurrence in any given year. These maps were developed to provide easy-to-interpret information that identifies areas at risk during flood events. The maps were developed using ESRI ArcGIS 8.1 software and are on the attached CD-ROM in ready-to-print PDF format. The CD-ROM format is compatible with Microsoft Windows Operating System Version 95 or later. The CD-ROM contains the HEC-RAS hydraulic model used to simulate flood elevations, digital coverages used to compose the maps, digital photos of bridge crossings and landscapes of the watershed, and this report. Graphs of channel thalweg and water surface profiles showing the depth of flooding for the biennial flood event (2-year flood) and the one-percent annual chance of occurrence flood (100-year flood) provide additional information.
