USGS Iowa Water Science Center

The U.S. Geological Survey's (USGS) mission is to provide reliable scientific information about the Nation's natural resources. An integral part of that mission is to provide consistent, long-term water-resources data to customers, cooperators, and the public. To accomplish our mission, we operate a widespread surface and ground-water data collection network as well as research a wide range of scientific issues throughout Iowa.

USGS Iowa Continuous Real-Time Water Quality Monitoring

The "Real-time" map tracks short-term changes (over several hours) of water quality. Although the general appearance of the map changes very little from one hour to the next, individual sites may change rapidly in response to major rain events or to reservoir releases. The data used to produce this map are provisional.

Iowa's Section 303(d) Impaired Waters Listings

Under Section 303(d) of the Clean Water Act, states are required from "time to time" to submit a list of waters for which effluent limits will not be sufficient to meet all state water quality standards. EPA has defined "time to time" to mean April 1 of even numbered years. The failure to meet water quality standards might be due to an individual pollutant, multiple pollutants, "pollution," or an unknown cause of impairment. The 303(d) listing process includes waters impaired by point sources and non-point sources of pollutants.

Iowa Department of Agriculture and Land Stewardship - Division of Soil Conservation & Water Quality

Land stewardship is central to the work of the Department of Agriculture and Land Stewardship. The Division of Soil Conservation provides farmers with expertise and funds to help them install practices that preserve our highly productive soil, prevent erosion and protect our critical waterways. The Department is focused on making sure future Iowans can experience the same high quality of life that past generations have enjoyed in our state.

Iowa Water Center

Established in 1964, the Iowa Center (IWC) is a federally funded program. Its purposes are to identify research needs and fund selected projects about Iowa’s water quality, water quantity, and the human dimensions of water-resources management, provide outreach and education opportunities to familiarize water-resource professionals, teachers, and students with current research about Iowa’s water resources, disseminate information about Iowa’s water resources to water-resource specialists, teachers, students, policymakers, and the general public.

Iowa Flood Center

The Iowa Flood Center (IFC) provides Iowans information to help individuals and communities understand flood risks. The IFC is actively engaged in flood projects in several Iowa communities and employs several graduate and undergraduate students participating in flood-related research. IFC researchers have designed a cost-efficient sensor network to better monitor stream flow in the state; have developed a library of flood-inundation maps for several Iowa communities; and are working on a large project to develop new floodplain map for 85 of Iowa’s 99 counties.
