Table 4. Agreement rules for comparing independent datasets with the U.S. Geological Survey perennial streams model for Idaho.
[Stream classification, USGS model: Perennial, stream reach with 7Q2 flow greater than or equal to 0.1 ft3/s; Transitional, stream reach where 7Q2 is 0.1 ft3/s ± 1 standard error; Not mapped, stream reach not on USGS model and assumed intermittent. Stream classification, Comparison dataset: See table 3. Abbreviations: USGS, U.S. Geological Survey; 7Q2, 7-day 2-year low flow, ft3/s, cubic foot per second]
