The Bonneville Power Administration (BPA), the United States Army Corps of Engineers (USACE), and the U.S. Bureau of Reclamation (USBR) perform hydroregulation studies of the Columbia River basin for analysis of environmental impacts, changes to operation criteria from Biological Opinions, power revenue forecasts, flood control studies, operations planning, . Objective 1: To assess and further develop statistical seasonal streamflow forecasting model for forecasting reservoir inflows across the MDB. The relationship between El Niño/Southern Oscillation (ENSO) and climate is the scientific basis of seasonal climate forecasts provided by research institutions andFile Size: 77KB.

Wellman, Janice M. Gordon, and Robert L. Moffatt ABSTRACT Statistical summaries of streamflow data at stream-gaging sites are presented to aid in appraising the hydrology of river basins in by: 7. Updated statistical summaries of streamflow characteristics are presented for streamflow-gaging sites in Montana and adjacent areas having 10 or more years of record for water years through Data include the magnitude and probability of annual low and high flow, the magnitude and probability of low flow for three seasons (March.
Statistical summaries of streamflow data at stream-gaging sites are presented in this report to aid in appraising the hydrology of river basins in Western Oregon. Records for 21 gaging stations were compiled into separate periods owing to changes in regulation during the period of Cited by: 3.

states and additional territories. Our hydrologic monitoring stations continue to send data in near real-time to NWISWeb, and we are continuing critical water monitoring activities to. Statistical summaries of streamflow records through for gaging stations in Oklahoma and parts of adjacent states are presented for stations with at least 10 years of streamflow record.
Streamflow at of the stations is regulated for specific periods. Data for these periods were analyzed separately to account for changes in streamflow because of regulation by dams or.

Existing tools, features, and web data services are being fully maintained as before, but new tools and enhancements will no longer be developed. The fourth program (QSTATS) is designed to facilitate statistical analysis of streamflow data.
The fifth program (MkDF) is a preprocessor to create batch input files for the U.S. Environmental Protection Agency DFLOW3 program for calculating low-flow statistics. Mean Daily Flow: cfs @ 05/10/ Instantaneous Flow: cfs @ 05/11/ Instantaneous Stage: ft @ 05/11/ In the first phase, we undertook a two-year field validation study of a Interim SDAM for Oregon.
We then constructed a new, more accurate method based on statistical analysis of the Oregon field data identifying the best indicators to discriminate streamflow duration classes.
information is presented in the USGS Open-File Report titled “Statistical Summaries of Streamflow Data in Oregon: Volume – Mo1 nthly and Annual Streamflow, and Flow-Duration Values.” Exceedance statistics for Washington gaged basins near the Oregon border are in the USGS Open-File Reports A and B.
The U.S. Geological Survey stream-gaging program provides streamflow data for a variety of purposes. The uses of streamflow data are described, and the growth of the stream-gaging program is related to legislation and the need to manage the Nation's water resources more effectively.
A brief description is provided of the data-collection. Chapter 5 Streamflow Data Introduction Streamflow data collected by various agencies de-scribe the flow characteristics of a stream at a given point.
Normally, data are collected by using a measur-ing device commonly called a stream gage. Streamflow data are used to indicate the present hydrologic conditions and the discharge amounts of a. Washington Current Streamflow Summary Map: description: Typically this means insufficient historical data exists to compute a percentile, or there is no current estimated flow information available.

Time series, trend and dependability analysis were performed.
The methods used and the results of analysis are given in this chapter.in Oregon highlighted the need for an alternative method to more accurately determine streamlow duration.
Analyses of the Oregon data found that a subset of the Interim Method and supplemental indicators appeared to have the strongest explanatory power in separating the perennial, intermittent, and ephemeral stream classes.
