Explanation
§ The funding from this agreement is used to maintain the rain and stream gauge system in the City of Charlotte stream network.
§ Since 1961, the City of Charlotte has worked with the United State Geological Survey (USGS) to gather rainfall and stream flow information through a cost-sharing program. The previous agreement was for a five-year period and approved by City Council on November 13, 2017.
§ The rain and stream gauge system for the City of Charlotte is part of a nationwide network that measures quantity and quality of surface water resources.
- A rain gauge electronically collects and transmits the amount of rain at the location the gauge is stationed. The gauge transmits rainfall amounts to the USGS office for compilation.
- A stream gauge electronically collects and transmits information about the water within streams and lakes. The gauge collects and transmits elevation, temperature, and flow information to the USGS office for compilation.
- There are 29 stream gauge stations and 38 rain gauge stations in the City of Charlotte stream network.
§ Data from the gauge system is used to:
- Determine flood-prone areas,
- Review rain event impacts,
- Determine long-term trends,
- Aid in surface water quality investigations,
- Assist in drainage infrastructure design, and
- Notify emergency personnel of potential threats to life and property.
§ The agreement with USGS is for a five-year period. The total five-year cost is $3,597,800. The city’s share payable to USGS on 29 stream gauges and 38 rain gauges is $2,254,100, with USGS funding the remaining $1,343,700.
§ Mecklenburg County has a separate annual agreement with USGS and shares the cost on 24 stream gauges and 36 rain gauges.
