The monitoring network within this area

Hydrionis holds 611 values from 7 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.

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 — 05050001. 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.

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.

Source: USGSNational Water Information System, USGS site 03161000, parameter 00060, annual mean statistics. Licence: Open.

Method: Annual mean discharge as published by the USGS statistics service, computed by USGS from its own quality-controlled daily record. Hydrionis converts cubic feet per second to cubic metres per second and records the publisher unit alongside; it does not recompute the mean.

Data from the U.S. Geological Survey National Water Information System, a work of the United States government and therefore in the public domain.
