- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
PERIOD OF RECORD.--DAILY GAGE HEIGHT--October 2000 to current year.
The peak flows published from 1906-1934 for the Cannonball River near Timmer, ND were used to transfer the corresponding peak flow to Cannonball River at Breien based on a drainage area conversion done in the 1950s. Equation is Q=(DA1/DA2)^C, where Q is calculated Cannonball River at Breien's discharge, DA1 is Breien drainage area, DA2 is Timmer drainage area, and the coefficient (C) used was 0.50. The Timmer peaks from 1903-1905 were not included in the transfer due to the inability of accurately determining the momentary peaks from these years.
Peaks from 1906, 1908, 1913, and 1934 are based on unpublished momentary peaks from Timmer. The peaks from these years were not revised due to the uncertainty of the momentary peaks.
Datum of the gage is 1,675.02 feet above North American Vertical Datum of 1988 (NAVD88) and 1,673.54 feet above National Geodetic Vertical Datum of 1929 (NGVD29).
For a detailed gage datum history, please use the blue ‘questions or comments’ tab on the bottom of the site’s monitoring location page.
Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years.
