Stream gage levels in Nevada, relative to 30 year average.

Explanation
	High
	> 90th percentile
	76th - 90th percentile
	25th - 75th percentile
	10th - 24th percentile
	< 10th percentile
	Low
	Not ranked

The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.

The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

The data on these pages is made possible with the cooperation from Federal, Tribal, State, and local agencies.

Current conditions data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to the Nevada Water Science Center Office hourly. Recording and transmission times may be more frequent during critical events. Data from current condition sites are relayed to the Nevada Water Science Center via satellite; telephone and radio are also available at some sites for viewing data within minutes of arrival. All current conditions data are provisional and subject to revision.
