Water Resources of New Hampshire and Vermont provides the latest information on drought conditions and rainfall data for the area; water data including streamflow and ground-water levels; and streamflow maps showing watersheds. There are also U.S. Geological Survey (USGS) publications, including reports on USGS projects; USGS news and events; and educational links. Full description.

The U.S. Geological Survey (USGS) Water Resources of South Dakota site contains hydrologic data, including realtime streamflow, precipitation, and water use data. There are USGS water resources publications and information on projects such as the Black Hills Hydrology Study; the National Water-Quality Assessment (NAWQA) Volatile Organic Chemicals National Synthesis; the Belle Fourche Watershed Assessment ...

This activity demonstrates how different sizes of rock materials that make up an aquifer affect water movement. Students discover that ground water must be able to move through underground materials at rates fast enough to supply useful amounts of water to wells or springs in order for those materials to be classified as an aquifer. They also learn that for water to move in an aquifer, some of the ... Full description.

This activity will help younger students learn what groundwater is and observe some of the components of a groundwater system. Students will see what groundwater looks like and learn some basic groundwater vocabulary. They will observe aquifers, surface water, water table, saturation zone, infiltration, and recharge. The activity requires common household items and can easily be done as a home project ... Full description.

ThinkQuest is a global network of students, teachers, parents, and technologists dedicated to youth-centered learning on the internet. This site contains information about limnology and its relevance. Topics covered include the water cycle, water types, catchments, algae, and limnology tests (pH, phosphate, salinity, turbidity, nitrates). There are experiments for the classroom and a case study on ... Full description.

In this activity, students look at the topography and cross-section of El Paso Texas and Edwards Aquifer in virtual reality, using historical data of the Edwards Aquifer that contains information on recharge, discharge and precipitation. From this data, conclusions can be made about future discharges of the aquifer. Full description.

U.S. Geological Survey (USGS) Water Resources of Georgia contains a map of current streamflow conditions; Georgia HydroWatch, a portal to hydrologic data and related information for Georgia; a listing of projects being conducted by the USGS in Georgia; and publications such as abstracts and full reports for USGS projects in Georgia. The water data includes flood-frequency information, low-flow frequency ... Full description.

This course addresses basic questions of how watersheds function at the plot-hillslope-catchment scale, such as: 'Where does water go when it rains?', 'How long does it reside in the watershed?', and 'What pathway does it take to the stream channel?' Materials include a series of benchmark papers and other textual resources, and a series of video lectures and virtual field trips. Full description.

This resource explains that water levels are part of the ebb and flow of nature and the difference between the amount of water coming into a lake and the amount going out is the determining factor in whether the water level will rise, fall or remain stable. Students will learn that there are three types of water level fluctuations: short-term changes due to winds or changes in barometric pressure, ... Full description.
