Radio-telemetry network used by the U. S. Geological Survey for reporting hydrologic data in Western Washington

This paper describes the extent of the hydrologic data telemetry network, the type and capability of equipment used for reporting and processing the data, the types of sensors being employed, and some of the many problems experienced in installing and operating the network in western Washington. The equipment was installed by the U.S. Geological Survey in cooperation with the City of Tacoma and the Puget Sound Power and Light Company. At present it consists of a computer-operated base station, two repeater radios, four remote telemetry stations reporting data from snow survey courses, and six remote telemetry stations reporting data from stream gages. The form of data reporting is analog and processing is digital.
