This flow information reflects conditions only at the time measurements were taken.  Flows marked "est" or "rough" are estimates based on other flow values, and may therefore be wildly inaccurate (see Estimate Information).  In addition, release changes, rainfall or snowmelt can cause dramatic changes to all flows.  Therefore, actual flows may differ significantly from the ones listed here.

Estimate Information

All Dreamflows estimates are estimates - which means they may well be incorrect.  For this reason, don't undertake expensive or time-consuming trips based solely on the estimate (or if you do, accept the possibility of being skunked).  Always try to confirm the sanity of the estimate by means of rainfall, snowpack, similar flows in similar drainages, word of mouth, etc.

Note 1  Confidence information appearing in the Comments column of the report means Dreamflows calculated the flow using a statistically-derived model.  In that case, two things.  Firstly, that confidence information is theoretical - it's based on the available historical data, which may or may not cover the current water year type.  Secondly, a confidence of (say) 85% sounds wonderful, but don't forget that also means there's a 15% chance the actual flow will be outside the given range.  You can report the accuracy of an estimate by visiting the river-levels webpage.

Note 2  Reservoir calculations are based on storage change.  Though useful indicators of flow trends, they can at times be amazingly inaccurate, especially if the reservoir is large.  See the Dreamflows FAQ for details.

Note 3  When gauge height is available but river flow is not, where possible, Dreamflows converts gauge height to river flow using a rating table.  The rating table used is the most currently-available, but still usually out-of-date, so the reported flow will probably be inaccurate to some extent.  You can report the accuracy of an estimate by visiting the river-levels webpage.

Note 4  Good-faith projections by the operating utility are usually reliable, but even so the scheduled releases might not occur, or be different than projected.  Reasons for this include (but are not limited to) operational, health, safety and legal.

Note 5  Informal projections by the operating utility are usually fairly reliable, however they can (and sometimes do) change radically without notice.  It's good to take these predictions with a grain of salt.
