1st report never published by the state; an extract from it is given in the Transactions of the Geological Society of Pennsylvania, v. 1, p. 240-243. A brief summary of the 2d report was published in the Tennessee House journal for 1833, p. 303-305. A 10th report was presented to the House in 1850 and printed, but no copy of it can now be found.--cf. L.C. Glenn, in American geologist, v. 35, no. 2, p. 82-89.

Survey of Users of the USGS Stream-Gaging Network in Iowa, 1996, HR-383, 1996

A survey was sent to over 200 Federal, State, and local agencies that might use streamflow data collected by the U. S. Geological Survey in Iowa. A total of 181 forms were returned and 112 agencies indicated that they use streamflow data. The responses show that streamflow data from the Iowa USGS stream-gaging network, which in 1996 is composed of 117 stations, are used by many agencies for many purposes and that many stations provide streamflow data that fulfill a variety of joint purposes. The median number of respondents per station that use data from the station was 6 and the median number of data-use categories indicated per station was 9. The survey results can be used by agencies that fund the Iowa USGS stream-gaging network to help them decide which stations to continue to support if it becomes necessary to reduce the size of the stream-gaging network.

Iowa's frog and toad survey, 1995-2003.

This survey began in response to widespread interest of declines in amphibians. More recently, a comprehensive statewide planning group discovered 44% of Iowa’s herpetofauna (amphibians and reptiles) to be of special concern. In response to these concerns, the Iowa Department of Natural Resources Wildlife Diversity Program (WDP) initiated an auditory survey for calling anurans to determine geographic distributions within the state. This survey has established itself as an extensive, long term monitoring program. This 2005 report is the second edition since the first report of this survey was shared in 1998 by then program biologist Lisa Hemesath. The goals of the survey are to: (1) determine the distributions of Iowa’s anuran species, (2) determine population trends for each species, and (3) promote education about aquatic life by using volunteers to conduct the survey. In addition to Iowa, volunteer-based auditory surveys for frogs and toads are currently being used in the Midwest by Wisconsin, Minnesota, Missouri, and Illinois.

St. Louis, Missouri and vicinity, 1903 (Raster Image)

This layer is a georeferenced raster image of the historic, topographic paper map entitled: Saint Louis quadrangle, Missouri - Illinois, [by the] Department of the Interior, U.S. Geological Survey; H. M. Wilson, geographer; topography by Chas. E. Cooke, Wm. O. Tufts, Gilbert Young and City of St. Louis; control by U.S.C. and G.S. and Geo. T. Hawkins. Ed. of Apr. 1904, reprinted 1932. Surveyed 1903. It was published by U.S.G.S. Scale 1:62,500. Covers City of Saint Louis, and portions of Saint Louis County, Missouri, and Saint Clair and Madison Counties, Illinois. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Missouri East State Plane Coordinate System NAD27 (in Feet) (Fipszone 2401). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This is a typical topographic map portraying both natural and manmade features. It shows and names works of nature, such as mountains, valleys, lakes, rivers, vegetation, etc. It also identify the principal works of humans, such as roads, railroads, boundaries, transmission lines, major buildings, etc. Relief is shown with standard contour intervals of 20 feet and spot heights. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
