Groundwater Level Network

The Water Monitoring Section of the Iowa Department of Natural Resources and the United States Geological Survey cooperate on the Water Level Well Network. This network consists of 159 wells in different aquifers (see map) whose water levels are measured at least quarterly. The aquifers monitored are Alluvium, Pleistocene, Cretaceous, Mississippian/Pennsylvanian, Silurian/Devonian, and Cambrian/Ordovician. The formal water level network was started in 1982, however some water level data exists prior to this time period for certain wells. Monitoring was suspended in 2004 due to budget cuts and will resume in 2005 for the Cambrian-Ordovician aquifer.
