Water resource and hydrology investigations require summaries and analysis that use available hydrologic data in standard formats, period, and methods so that the information is consistent and allows direct comparison from one site to another. To fulfill this goal a project was initiated in the 1995-1996 fiscal year with funding by the Corporate Resource Inventory Initiative (CRII). The culmination of this project was the production of the report, British Columbia Streamflow Inventory (BCSI), by the Resources Inventory Branch in the 1997-1998 fiscal year. That report presents a summary of streamflow data compiled in datasheet, map and graphical forms and covers the whole province. The purpose of this information is to enable hydrologists and engineers to make hydrologic estimates for water management and the planning and preliminary design of water resource projects. A separate project, which is a direct progression of the above work, was initiated in the 1998-1999 fiscal year and was also, funded by CRII. The purpose of this study was to characterize the variability of streamflow parameters in ministry regions, based on the summary data and hydrologic zones defined in the BCSI report. This approach with subregional hydrologic zones, or subzones, and graphs will enable more accurate estimates, suitable for design streamflows, to be applied to ungauged watersheds. The subzones are a product of the application of additional hydrologic data and regionalization procedures to those applied in the study of the BCSI report. This work will form the basis of a future revision of the BCSI hydrologic zones. The first of a series of reports in this study was published in December 1998 for the Southern Interior region and the second in September 1999 for the Cariboo region. This report is a continuation of the current CRII study and covers the ministry Omineca-Peace region that incorporates hydrologic zone 5 and 6 and the contiguous portions of the eastern and southern zones, as defined in the BCSI report. The report contains summary data that were extracted from the BCSI report, the graphical procedures used to derive the subzones and the procedures for estimating streamflow at ungauged watersheds. However, before any estimates are finalized using this report, reference should be made to the Water Inventory Section hydrology report and map libraries and the Ministry library in Victoria for comparison and any additional hydrologic data that may prove useful. |
