2024 Restoration Flow Release Schedule

Current Flows

Most data shown here are from the USGS via the waterservices site, plus the USBR and CDWR via the California Data Exchange. Data are provisional and may be recalculated before final approval. The TRRP site checks for new sub-daily values every 15 minutes and for new daily values twice per day. Note that “Full Natural Flow” is an automated estimate from CDWR of the flow that would naturally pass the Trinity Dam site if unimpeded – it is very sensitive to small variations in lake level measurements that may result in negative values when flows would naturally be low, but is more useful for storm events, snowmelt, and averages over longer times. The graphic for water released to the Trinity River versus the water diverted to the Central Valley tends to show higher values for the river ​until summer, when water exports ​to the Central Valley ​typically increase.
