Ground-Water Information and Data
The U.S. Geological Survey (USGS) ground-water network for Montana currently consists of 28 wells. Ground-water levels are continuously monitored in 18 wells, ground-water levels in the other 10 wells are manually measured 4 times a year. The 18 continuously monitored wells are located throughout the state. Water levels in many of the continuously recorded wells located in Western Montana are influenced by irrigation. Satellite telemetry equipment installed at two of the wells transmit realtime data every 4 hours. The other 16 continously monitoried wells in the network record data at the wellhead and are retrieved every 6-8 weeks. The 10 manually measured wells are located in the northwest part of the state.

Ground-Water Networks
- Active Water-Level Network:
 Quick look:
The Active Ground-Water Level Network contains water levels and well information from more than 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 365 days. This network includes all of these wells, regardless of measurement frequency, aquifer monitored, or the monitoring objective. For more information about this topic, click now.( )

- Climate Response Network: Quick look:
The USGS maintains a network of wells to monitor the effects of droughts and other climate variability on ground-water levels. The network consists of a national network of about 140 wells monitored as part of the Ground-Water Resources Program, supplemented by wells in some States monitored as part of the Cooperative Water Program.

- Real-Time Network Quick look:
Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.
