Great Lakes SPARROW Mapper, 2002

This mapper displays SPARROW nutrient load and yield data specifically for U.S. tributaries to the Great Lakes. The results are based on the SPARROW models developed for the Great Lakes, Ohio, Upper Mississippi, Red River Basins (MRB3). Modeling results can be exported as an Excel spreadsheet or a geospatial dataset.

Mississippi/Atchafalaya River Basin (MARB) SPARROW Mapper, 2002

The mapper displays SPARROW nutrient load and yield data and the importance of various nutrient sources for the MARB, given nutrient inputs similar to 2002. Rankings can be shown by major watershed, state, HUC8, tributary, and catchment. Nutrient data can be explored using maps and interactive graphs and tables. Modeling results can be exported as an Excel spreadsheet or a geospatial dataset...

Colorado Flood Database and Interactive Map

Data on 6,767 flood events at 1,597 individual sites throughout Colorado were compiled to generate the flood database. The data sources of flood information are indirect discharge measurements that were stored in U.S. Geological Survey offices (water years 1867–2011), flood data from indirect discharge measurements referenced in U.S. Geological Survey reports.
