| Dataset | Dates of field visits | Classification method | Number of sites | ||
|---|---|---|---|---|---|
| No. | Source | Name | |||
| 1 | Idaho Department of Environmental Quality | IDEQ BURP | Summer/autumn 1993–2006 | Streams were coded perennial if measured flow during field visits was greater than or equal to 0.1 ft3/s; otherwise, streams were coded intermittent. | 1,804 |
| 2 | U.S. Environmental Protection Agency | EMAP office | No dates; determinations made in 1999 | Made using several office-based approaches, including examining maps and GIS coverages and talking to regional biologists and State employees with knowledge of the area. No field visits. | 114 |
| 3 | U.S. Environmental Protection Agency | EMAP field | Summer/autumn 2000–2003 | Streams were coded perennial if enough water was present to sample during field visits; otherwise, streams were coded intermittent. | 123 |
| 4 | U.S. Geological Survey | USGS low flow | Throughout year 1945–2001 | Field visits made throughout the year, but mostly in summer/autumn. Sites were used for model comparison only if site was dry, water was pooled, or measured flow was <0.1 ft3/s (to be comparable with BURP sites). Sites selected were considered intermittent. | 207 |
