The State Water Board has requested services from United States Geological Survey (USGS) for streamflow gaging on Shasta River (tributary to the Klamath River). The monitoring will follow standard USGS streamflow gaging practices and will specifically include bridge-mounted installation consisting of a bubble-gage orifice (gas purge system and pressure transducer) and a data collection platform (DCP) for data storage and telemetry. The data will be telemetered and posted to the USGS National Water Information System (NWIS) website.

Reasons for Exemption
This stream flow monitoring project is strictly for information gathering purposes.
