Peace Project Water Use Plan Annual Report: 2010 5 Summary of Peace WUP Projects This section outlines the status of each of the Peace WUP projects as of 30 June 2010 (financial status is covered in Section 6, below). Each subsection describes one project and includes: � the project objective, � a description of the project, � the contractor and the executive summary or equivalent from its latest annual report, and � the current status of the project. Physical works are described first, in Section 5.1, followed by monitoring programs in Section 5.2. 5.1 Peace WUP Physical Works Projects 5.1.1 GMSWORKS#1 – Peace River Aerial Photos Order Clause: Schedule C clause 1 BC Hydro Project Manager: Kim Hawkins 5.1.1.1 Overview Project Objective: The objectives of this project are to: � Conduct a mapping inventory to organize a bibliography of all existing maps associated with the Peace River, and � In Years 1 and 9 of this project, acquire aerial photos of the Peace River between the Peace Canyon Dam and the confluence with the Pine River, at five different flows within normal operating range. Project Description: The Peace River Aerial Photos project supports physical works and monitoring programs within all of the Peace River management plans. Specifically, this project will provide spatial data to support the PSP and the PCR Flood Pulse, PCR Side Channel, and PCR Ramping Plans. The project entails capturing photos, at a scale of 1:5000, at flows of approximately 10K cfs, 20K cfs, 70K cfs and 2 additional flow rates between 20K and 70K cfs. At least one set of photos is to be taken when foliage is present to form the basis of vegetation maps. The photos are to be orthorectified and both digital and hard copies of the map files delivered. Completion of any aerial photography not taken in Years 1 and 9 is to be conducted in Years 2 and 10. A status report will be completed after each year of work. Contractor: The mapping inventory work was conducted by Geomatics and Research. Aerial photography work is being conducted by Selkirk Remote Sensing Ltd., photogrammetrics scanning by Aero Geometrics Ltd. and aerial triangulation by BC Hydro Page 8
Peace Project Water Use Plan Annual Report: 2010 4DGIS Ltd. All three contractors have conducted similar work for BC Hydro in the past. The BC Hydro Photogrammetry Services Department provided project coordination, supervision and compilation assistance. ToR Status: In March 2009 the CWR approved a budget increase of $198,625 to reflect updated project implementation costs. The project complies with the revised ToR; no further resubmission is anticipated at this time. 5.1.1.2 Contractor’s Report 5.1.1.3 Status In 2009 the BCH Photogrammetry Services Department contracted and completed the following work on GMS Works #1: � On September 13, 2009 acquired 1:5000 scale photography of the Peace River from Peace Canyon Dam to the confluence of the Pine and Peace Rivers. The mission was flown with a constant discharge rate from Peace Canyon Dam at a flow of 10, 733 ft3/s. � On September 20, 2009 acquired 1:5000 scale photography of the Peace River from Peace Canyon Dam to the confluence of the Pine and Peace Rivers. The mission was flown with a constant discharge rate from Peace Canyon Dam at a flow of 21, 329 ft3/s. � The aerial photo negatives were processed and then scanned at a pixel size of 14 microns, as per Photogrammetric standards, the resulting scans were adjusted through a computer process of aerial triangulation and controlled by previous aerial triangulation of 2008 Photos. � After the aerial triangulation process was complete the aerial photographs were set into the Photogrammetric workstations and checked as to quality and completeness of coverage. The Photogrammetric department then imported the previously completed Digital Elevation Model and used this DEM to drape the photography in order to produce a high resolution orthophoto. � The final products were distributed to various users and archived in the BCH Photogrammetry department. This work was initiated in October 2008 when one set of photos were taken at midrange flow. In September 2009, two low flow situations were photographed. The remaining high flow photos will be taken between July and August 2010. A second set of photos are to be taken in Yr 9 (2016), and completed in Yr 10 (2017) if necessary. The bibliography of Peace River maps was completed in April 2009. 5.1.2 GMSWORKS#2 – Peace River Baseline TGP and Temperature Order Clause: Schedule D clause 1 BC Hydro Project Manager: Kim Hawkins BC Hydro Page 9
