ABSTRACT:
	Stream discharge data is collected at several small gaged catchments at the the Andrews Forest and other experimental watershed studies in Oregon (South Umpqua, Bull Run and Alsea). This database accompanies the discharge databases and describes the calibration equations used (also known as rating curves that determine discharge from stage height) and their application dates for many of these catchments. The calibration measurements used to develop rating curves are also presented for most of the Andrews Forest sites. Correction tables used to correct raw stage height data are also available for many time periods. Collection points consisting of synchronized hook gage stage height measurements alongside direct height measurements inside the flume are used to monitor this hook-gage to flume relationship over time for WS 1, 2, and 3. Descriptions of the weirs and rating curve histories are pending for posting along with watershed area and other spatial characteristics.

ENTITY TITLES:
2	Stream rating curve calibration measurements (Nov 19 1953 - Oct 18 2017)	METADATA	DATA
	Described measurement points are used in the creation of rating tables and curves for gaged watersheds
3	Rating equations for gaged watersheds (Oct 1 1949 - Sep 30 2017)	METADATA	DATA
	Rating equations used to convert stream stage height to stream discharge
4	Date ranges where individual rating curves are applied (Aug 25 1949 - Oct 1 2018)	METADATA	DATA
