One email when the flow at the gauge you pick crosses what you choose. We check the public USGS reading every 2 hours and email at most once every 6 hours, several waters in one message. Flow alone is not a fishing forecast or a safety call.

USGS gauge: HUERFANO RIVER NEAR BOONE, CO. (USGS 07116500)

When should we email you?

When the flow moves into or out of its usual range for the dateThe usual range is the 10th to 90th percentile of daily mean flow for the date, from 47 years of USGS record at this gauge: the range the flow cards call fishable. You hear when it goes low, comes back, or runs high.
When it crosses a flow I setYou pick the flow and the direction; the other way round re-arms the alert without an email.

The flow fields are used only with “a flow I set”.

Email address

How it works

The first reading after you follow is the starting point, so nothing is sent for it. After that we email only when a reading crosses what you chose, not every time we look; if several waters change, they come in one email. Every email names the gauge, the reading and its time, links the USGS gauge page, and has one-click links to stop alerts for this water or all flow alerts.

USGS marks recent readings provisional; they can be revised. A gauge that stops reporting sends nothing until it reports again.
