These historic photographs may be useful in documenting changes in the condition of the Platte River. Each of the photographs were scanned at 600dpi and compressed using M.zip software from LizardTech. M.zip compressed images may be viewed using a free viewing software package available from LizardTech. Software extensions allowing M.zip images to be used in Adobe Photoshop are also available. These photos are available on USGS Nebraska Water Science Center website at: http://ne.water.usgs.gov/platte/historical1938.html In addition to being provide in this ScienceBase record, the photographs are stored on USGS National Geospatial Program servers (web domain http://thor-f5.er.usgs.gov/platteriver/1938).

Description of Work USGS is creating forecasting tools for managers to determine how water withdrawals or other hydrologic or land use changes in watersheds may affect Great Lakes ecosystems. This project is determining fish distributions in Great Lakes tributaries and how changes in stream flow may affect them. This information will help guide restoration efforts to achieve maximum effectiveness and success. Estimates were produced using WATER - a TOPMODEL based tool that estimates streamflow at any point along the stream network. The pour point is selected using a point-and-click GUI that samples information about the basin using a geodatabase of topographic and soil data spatial layers.

Description of Work The Science in the Great Lakes (SiGL) Mapper is a map-based discovery tool that spatially displays basin-wide multi-disciplinary monitoring and research activities conducted by both USGS and partners from all five Great Lakes. It was designed to help Great Lakes researchers and managers strategically plan, implement, and analyze monitoring and restoration activities by providing easy access to historical and on-going project metadata while allowing them to identify gaps (spatially and topically) that have been underrepresented in previous efforts or need further study. SiGL provides a user-friendly and efficient way to explore Great Lakes projects and data through robust search options while...

This network of inland streams, wetlands and water bodies is a composite of two layers from the National Hydrography Dataset Plus (NHD+ flow lines and water bodies), and all available wetlands from the National Wetlands Inventory (NWI) and Wisconsin Wetlands Inventory (WWI). In combination, these layers provide a network template of inland corridors for assessing relative vulnerability to future invasions of Phragmites.

Habitat suitability was estimated for invasive Phragmites in the coastal Great Lakes region (shoreline to 10 km inland). These estimates were based on current distribution patterns and environmental conditions. Phragmites presence or absence was defined based on a distribution map produced by cooperative research between the GLSC and Michigan Technical Research Institute. Environmental variables were processed in a Geographic Information System (GIS) and came from existing publicly available sources. Variables include descriptors of soils, nutrients, topography, ecoregion, anthropogenic disturbance, and climate. Environmental conditions and Phragmites presence/absence were sampled in a GIS at points established...

The U.S. Geological Survey (USGS) GLRI effort is being coordinated and managed by the USGS Midwest Area in accordance with the USGS science strategy - one that is driven by cross-disciplinary integrative science and conducted in collaboration with partners to provide resource managers with the information and decision-making tools they need to help restore the Great Lakes.
