Basin Characterization Model - Simulating Effects of Iowa Soil Management on Water Availability

As a result of climate change, heavy rainfall, as well as extended dry periods, are becoming more common in the Midwestern United States. These trends are only expected to continue. So, increasing the capacity of soil to store water has become more critical. Storing water increases availability in dry conditions. And the absorption of additional water in wet conditions reduces potential...

Defining Native Ranges of U.S. Inland Fishes

Understanding the native versus non-native range of a species can provide useful information about dispersal, population distribution patterns, and human mediated movement across hydrologic barriers. The USGS Nonindigenous Aquatic Species (NAS) Program is working with partners to define native ranges of inland fishes in the United States to help identify which species should be included in the...

Iowa Alluvial Aquifer

This study is part of ongoing research in Iowa to investigate the availability (quantity and quality) of water in alluvial aquifers that are used for agricultural, domestic, municipal, and industrial supplies. Previous research included modeling and delineation of ground water flow in the Mississippi River, Des Moines River, iowa, and Cedar River alluvial aquifers. The water quality of these...

The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)

Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
