Crest-stage gaging stations in Oregon: a compilation of peak data collected from October 1952 to September 1974

Open-File Report

Prepared in cooperation with Oregon State Highway Commission, Federal Highway Commission, Bureau of Land Management



A crest-stage gaging station provides an excellent means for determining peak water-surface elevations at a selected location on a stream channel. When related to streamflow, these data provide hydrologists with a knowledge of the flood experience of a drainage basin. If an adequate flood history is known, it is possible to estimate the probable magnitude and frequency of floods likely to occur in that basin, and this information is a valuable asset to anyone who must estimate design floods at proposed drainage structures. However, most design problems involve estimating peak flows on ungaged streams. This is difficult because the rate of storm runoff is not the same in all basins due to the influence of various basin characteristics which can either assist or retard the runoff. The crest-stage gaging program in Oregon is designed to provide a representative sampliing of peak flows at basins having a wide range in characteristics. Then, after sufficient data are collected, a statistical analysis can be made which will provide a means for estimating design floods at ungaged sites on the basis of known basin characteristics.

This report is one of a series presenting a compilation of peak data collected at 232 crest-stage gaging stations in Oregon. The collection and publication of these data are made possible through mutual funding by State and Federal agencies. The Geological Survey, the Oregon State Highway Commission, the Federal Highway Administration, and the Bureau of Land Management are currently supporting 160 active crest-stage stations in Oregon.
