New Monitoring Wells Along the San Joaquin River

jnickles - at - usgs.gov (Jim Nickles) — Wed, 19 Aug 2009 00:00:00 EST

The US Geological Survey has begun drilling monitoring wells as part of the San Joaquin River Restoration Program, in California's Central Valley. This video documents how USGS research drillers are installing wells to monitor groundwater at several river locations.

These wells will help USGS and other agencies track groundwater conditions near the river as additional water is released from Friant Dam as part of the restoration effort.

The San Joaquin River Restoration Program (SJRRP) is a comprehensive long-term effort to restore flows to the San Joaquin River from Friant Dam to the confluence of the Merced River and restore a self-sustaining Chinook salmon fishery in the river while reducing or avoiding adverse water supply impacts from restoration flows.

The Role of Hydrography in The National Map

Thu, 13 Aug 2009 00:00:00 EST

Water is vital to our Nation and the U.S. Geological Survey plays an important role in the tracking and mapping our water resources. The National Hydrography Dataset component of The National Map supports this mission and is widely used in the study of hydrology, natural resources, and pollution control. Users of USGS geospatial data discuss the role of the National Hydrography Dataset in water rights management in California, fisheries management in Michigan, and drinking water threat analysis nationwide.

Model of Floodplain Inundation (1998)

The Mississippi embayment — Where Does the Water Come From?

brclark - at - usgs.gov (Brian Clark) — Mon, 26 Jan 2009 00:00:00 EST

As the animation begins, the land surface of the Mississippi embayment fades away to reveal underground geologic formations (shown as shades of blue, brown, and gray surfaces). A slice deep into the earth cuts off the eastern half of the embayment so we can peer into the formations (aquifers) beneath the surface. The lower portion of different colored water wells (orange, light blue, and dark blue lines) come into view as the formations rotate. Each color of the wells represents a different layer of sand (aquifer) from which water is pumped. The wells are drilled from tens of feet deep to over 1,000 feet below land surface. There are thousands of wells represented here, but there are many thousands more that are not shown. All together, these wells pump, on average, enough water out of the ground to cover an average size county in about six inches of water -- everyday. This animation is another piece of the 3D computer model puzzle used to help manage the valuable water resource.

The Mississippi embayment — a look underground

brclark - at - usgs.gov (Brian Clark) — Tue, 16 Dec 2008 00:00:00 EST

Water, oil, and gas wells (shown as green lines) are drilled to hundreds or thousands of feet below land surface in an area known as the Mississippi embayment. Information gathered from these wells was used to create a 3D computer model of underground formations. Many of these formations (shown as shades of grey, blue, brown, or tan surfaces) consist of layers of sand and clay. These formations are important because they contain ground water that can be pumped out of the ground and used for anything from drinking water for public supplies to irrigation water for crops to washing, cooling, or transporting products in industrial settings. With the ever increasing demand for water and concerns about availability and sustainability, visual tools such as this are important and helpful.
