  NOTE: Attempts to retrieve a large set of data may fail.
Consider obtaining data in comma-separated-value (CSV) format or SHEF format for more than 800 data points. Or retrieve daily data, where available, for long time periods rather than hourly or event data.

For reference, check the Station Information page for a list of Real-Time Stations, Daily Stations, Monthly Stations, precipitation sensors, reservoir stations, or river gage stations. To generate custom lists, please use the CDEC Station Search.
