Beaver
2 monitoring stations within this area in United States, holding 63 values between 1912 and 2026. A United States federal hydrologic unit at the eight-digit subbasin level — a drainage area, not a river. Many subbasins take the name of the largest river within them, and the gauges below are anywhere inside the area, including on tributaries.
The monitoring network within this area
Hydrionis holds 63 values from 2 gauges within it. Discharge is a property of a gauge and its reach, not of this drainage area, so this page reports the network and its records rather than a single figure.
Flood peaks, as measured
This gauge's flood record, as measured. Unlike a daily mean it is the discharge at the moment the river was highest, which is the figure flood frequency analysis is built on.
Published by the gauge's own operator from its sub-daily record; Hydrionis stores the figure rather than recomputing it. A year the gauge did not cover produces no value rather than a low one, and the gaps are stated below the chart. A peak is a property of this gauge and its reach: a larger flood upstream or downstream of it is not in this series.
What the shaded periods are (1 event)
A shaded period marks when something was recorded, not what caused the shape of the line. Where the two coincide, they coincided.

| How the values came to exist | Measured |
| Period held | 1982–2024 |
| Completeness | 86.0% of the periods in that span are held. Gaps are drawn as breaks and never interpolated. |
| Known gaps |

| Continuity | The record begins in 1982 and is not continuous from it: 43 years separate the first value from the last, and 86% of the years between them are held. The span is not the record. |

How these gauges were attached to this water
Assigned by the publisher to a numbered basin Every gauge here is assigned to this drainage area by its own publisher, which issues the area an official code — 10050014. A drainage area is not a river: it contains the tributaries as well as the main channel, and a gauge in it may be on any of them.
| Gauge | Evidence | Established |

What this record holds
Hydrionis decides which waters get a page, and which of those are offered to search, from what is actually held rather than from how the page reads. Five signals are counted; this record has 2 of them, which makes it a profile, not indexed.
| Signal | Held | Counts |
|---|---|---|
| Gauges holding a real record | 0 | no |
| Years spanned | 115 | yes, 20 or more |
| Values held | 63 | no |
| Distinct measurements | 2 | yes, 2 or more |
| Publishers measuring it | 1 | no |
| Official identifiers | 1 | recorded, not counted |

Where these figures come from
Source: USGS — National Water Information System, USGS site 06166000, annual peak streamflow. Licence: Open.
Method: The instantaneous maximum discharge of each water year as published by USGS, dated to the day it occurred. One value per October-to-September water year; where the publisher lists both a systematic and a historic peak for a year, the larger is the annual maximum. Values the publisher marks as maximum daily averages are not held here, because they are not instantaneous peaks. Values marked as bounded rather than measured are held as censored observations carrying the bound. Cubic feet per second are converted to cubic metres per second and the publisher unit is recorded alongside.
Rating curves are extrapolated at extreme discharges, so the largest values in a peak series carry the largest measurement uncertainty. Data from the U.S. Geological Survey National Water Information System, a work of the United States government and therefore in the public domain.
