Okay, I'm going to be a dick, that's a retarded question.
Two things get people's panties wet for no reason: ice on gauges telling you that Byers canyon has 2,000 cfs in January and sticks in gauges that tell you Boulder creek is running 1,500 in mid-April. Anytime its the off season, or just too good to be true, click on the gauge and see if the flow looks at all natural. If the rise isn't a smooth curve, then it's a equipment error.
The only time this rule does not apply is dam/tunnel releases, and even then it's within reason and they'll step up the flow in increments so as not to blast all the gravel beds to Kansas.
