National Park Service Visitor Spending Effects
The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...
North American Waterfowl Management Plan
The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats.
Developing a USGS Legacy Data Inventory to Preserve and Release Historical USGS Data
Legacy data (n) - Information stored in an old or obsolete format or computer system that is, therefore, difficult to access or process. (Business Dictionary, 2016) For over 135 years, the U.S. Geological Survey has collected diverse information about the natural world and how it interacts with society. Much of this legacy information is one-of-a-kind and in danger of being lost forever...

The National Map Small-Scale Collection
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
Long Term Resource Monitoring
This web resource provides decision makers with the information needed to maintain the Upper Mississippi River System as a viable multiple-use large river ecosystem.

Estimated Withdrawals and Other Elements of Water Use in the Great Lakes Basin of the United States in 2005
Estimates of water withdrawals in the United States part of the Great Lakes Basin and 107 of its watersheds designated by the 8-digit hydrologic unit code (HUCs) indicate that about 30.3 billion gallons per day (Bgal/d) were withdrawn for practically all categories of use in 2005. Virtually all water withdrawn was freshwater. Surface-water...
Mills, P.C.; Sharpe, Jennifer B.The April 18, 2008 Illinois earthquake: an ANSS monitoring success
The largest-magnitude earthquake in the past 20 years struck near Mt. Carmel in southeastern Illinois on Friday morning, 18 April 2008 at 09:36:59 UTC (04:37 CDT). The Mw 5.2 earthquake was felt over an area that spanned Chicago and Atlanta, with about 40,000 reports submitted to the U.S. Geological Survey (USGS) “Did You Feel It?” system. There...
Herrmann, Robert B.; Withers, M.; Benz, H.Preliminary results of a dam-removal analysis on brewster creek near st. Charles, Illinois, 2002-2004
The benefits of gradually removing a dam (through multiple notches) are to reduce the total project cost and reduce possible environmental effects by allowing the impounded sediment to slowly move downstream, and a stable stream and revegetated floodplain to form upstream. Notching, in this study of a dam on Brewster Creek, near St. Charles,...
Kosky, K.M.; Straub, T.D.; Roseboom, D.P.; Johnson, G.P.St. Louis Metro East region sediment and geomorphic study
Judy's Branch, a small basin (8.64 mi2) near Glen Carbon, Illinois, is selected as a pilot site to determine sediment yield and channel erosion of streams draining the bluffs of the American Bottoms in the Metro East area of Illinois. This paper presents results of an on-going sediment and geomorphic study in Judy's Branch. The average suspended-...
Straub, T.D.Delineation of the Troy Bedrock Valley and particle-tracking analysis of ground-water flow underlying Belvidere, Illinois
The U.S. Geological Survey, U.S. Environmental Protection Agency, and Illinois Environmental Protection Agency began a study of the hydrogeology, flow system, and distribution of contaminants in the aquifers underlying Belvidere, Ill., and vicinity in 1992. As part of the study, the ancestral Troy Bedrock Valley, located about 1.5 miles west of...
Mills, P.C.; Halford, Keith J.; Cobb, R.P.Use of isotopes to identify sources of ground water, estimate ground-water-flow rates, and assess aquifer vulnerability in the Calumet Region of northwestern Indiana and northeastern Illinois
Isotope data collected in the Calumet Region of northwestern Indiana and northeastern Illinois, one of the most heavily industrialized regions of the United States, indicated that water in the surficial Calumet aquifer is well mixed. The Calumet aquifer is recharged areally by precipitation and locally may be recharged by surface water. The...
Kay, Robert T.; Bayless, E. Randall; Solak, Robert A.Estimated water withdrawals, water use, and water consumption in Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, and Wisconsin, 1950-95
From 1950 through 1995, the U.S. Geological Survey tabulated water withdrawals throughout the United States, including the northcentral States of Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, and Wisconsin. During this period, total water withdrawals increased in each of the north-central States by at least a factor of two. Illinois led...
Kay, Robert T.In Search of Easy-to-Use Methods for Calibrating ADCP's for Velocity and Discharge Measurements
A cost-effective procedure for calibrating acoustic Doppler current profilers (ADCP) in the field was presented. The advantages and disadvantages of various methods which are used for calibrating ADCP were discussed. The proposed method requires the use of differential global positioning system (DGPS) with sub-meter accuracy and standard software...
Oberg, K.Hydrogeology and simulation of ground-water flow in the aquifers underlying Belvidere, Illinois
The U.S. Geological Survey investigated the ground-water-flow system and distribution of contaminants in the vicinity of Belvidere, Illinois, during 1992?2000. The study included the compilation, collection, and analyses of hydrogeologic and water-quality data and simulation of the ground-water-flow system. Hydrogeologic data include...
Mills, P.C.; Nazimek, J.E.; Halford, K.J.; Yeskis, D.J.Equations for estimating Clark Unit-hydrograph parameters for small rural watersheds in Illinois
Equations for estimating the time of concentration (TC) and storage coefficient (R) of the Clark unit-hydrograph method were developed for small rural watersheds [0.02-2.3 square miles (mi2)] in Illinois. The equations will provide State and local engineers and planners with more accurate methods to estimate the TC and R for use in simulating...
Straub, Timothy D.; Melching, Charles S.; Kocher, Kyle E.Estimated water withdrawals and use in Illinois, 1992
The total amount of water withdrawn in Illinois during 1992 was about 19,076 (Mgal/d) million gallons per day. About 16,101 Mgal/d, or about 84 percent of this total, was withdrawn for thermoelectric-power generation, and about 1,877 Mgal/d was withdrawn by and delivered from public-supply facilities. About 1,910 Mgal/d of surface water was...
Avery, CharlesReaeration equations derived from U.S. geological survey database
Accurate estimation of the reaeration-rate coefficient (K2) is extremely important for waste-load allocation. Currently, available K2 estimation equations generally yield poor estimates when applied to stream conditions different from those for which the equations were derived because they were derived from small databases composed of potentially...
