Media Advisory: Officials, Scientists to Dedicate Showcase Gage on Rapid Creek

Release Date:

A U.S. Geological Survey streamgage will be dedicated by Congressional and city officials on September 3 in Rapid City. This showcase streamgage is located on Rapid Creek at Rapid City in Founders Park and will provide visitors with critical information about how streamflow is measured and other water-resource issues related to floods, droughts, water supply and recreation.

Reporters: A photograph of the showcase gage is available online.

The Rapid Creek at Rapid City streamgage has one of the longest periods of record in South Dakota, with continuous discharge since July 1942.  The new showcase gage has an outreach or public education purpose in addition to measuring flow. The gage house was designed to fit in and be part of Founder's Park.

The streamgage features three display windows that can be changed and updated over time. Current displays explain how a streamgage operates, describes the history of flooding along Rapid Creek, and provides a summary of the efforts by the City of Rapid City to improve water quality of urban runoff.  A graph of the historical flows is provided with a QR code that will allow visitors to rapidly learn the current gage height and streamflow discharge from a smartphone or other mobile device.

The largest peak discharge at this location was estimated as 50,000 cubic feet per second during the historic 1972 flood. This flash flood took 238 lives and was among the deadliest flash floods in U.S. history.

The streamgage is operated in cooperation with the City of Rapid City and the U.S. Army Corps of Engineers.

For more than 125 years, the USGS has monitored flow in selected streams and rivers across the U.S. The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, determination of flood risk and for many recreational activities.
