Description Usage Format Source Examples

Description

The daily mean gage height at streamgages in the Big Wood River Valley, Idaho. Gage height records bracket the 1987-2014 and are based on records with quality assurance codes of working (‘W’), in review (‘R’), and approved (‘A’).

Format

An object of data.frame class with 9,980 records and the following variables:

Date

date during which gage height was averaged.

13135500

daily mean gage height in meters, recorded at the USGS 13135500 Big Wood River near Ketchum streamgage.

13139510

daily mean gage height in meters, recorded at the USGS 13139510 Big Wood River at Hailey streamgage.

13140800

daily mean gage height in meters, recorded at the USGS 13140800 Big Wood River at Stanton Crossing near Bellevue streamgages.

Source

Data queried from the National Water Information System (NWIS) database on December 15, 2014, by Ross Dickinson (USGS). Records recorded on May 26-28, 1991 and March 15-22, 1995 were reassigned quality assurance codes of ‘I’ because of assumed ice build-up. Missing data at the Big Wood River near Ketchum gage was estimated using a linear regression model based on recorded gage-height data at the Big Wood River at Hailey and Near Ketchum streamgages. Missing data at the Stanton Crossing near Bellevue gage was replaced with average gage-height values recorded at this gage.
