AI summary The RETScreen model uses a 30% exceedance case from the Cornwallis River as a conservative estimate for annual generation. The design flow of 3.39 m³/s is based on existing infrastructure and historical data, but its accuracy is limited by the lack of site-specific records. Sensitivity scenarios (10%, 30%, 70%) were used to evaluate project performance under varying water availability conditions.

3.5 Creager Diagram A series of Canadian floods was plotted on the Creager Diagram (Neill, 1986) as shown i[n Figure 3.3.](#page-0-82) The Creager Diagram is an envelope for Probable Maximum Flood (PMF) based on gauged extreme events by re...

AI summary The Creager Diagram is used to plot Canadian floods, including the Probable Maximum Flood (PMF) for Factorydale Dam, which has a watershed area of 92.3 km2 and a predicted PMF peak runoff of 557 m3/s. The diagram shows the PMF envelope based on drainage area and unit discharge, with Factorydale Dam falling within the lower quartile but aligned with other extreme Canadian flood events.

A surface level evaluation of the impacts of a dam breach and the present flood mapping from the 2011 EPP was completed as part of this assessment. When the flood mapping was completed in 2007, surveying and dimensioning was completed down...

AI summary The assessment evaluated the impacts of a dam breach using the 2011 EPP flood mapping, identifying 20 residences and 5 bridges at risk during an AEP1,000 event. It noted that the 2007 assessment may have overclassified the dam by not accounting for incremental flood failure risk or using the CDA standard. The DV value is used to assess life safety risks, with the OMNR guideline assuming no fatality risk for DV values below 4 ft²/s.
