4. The Sooke watershed has an area of 34.92km^2.The characteristics of the watershed include a large lake (Sooke Lake), which takes up a significant amount of the watershed. The outlet of the watershed is the Sooke Dam, at the south end of Sooke Lake. Its characteristics include entirely forested, with an elevation ranging from 182-841m. It is a very important watershed, it supplies water to 350 000 people in the greater Victoria Area (CRD). According to the hypsometric profile, the Sooke watershed is composed of primarily lower elevations, with 50% of the basin falling below approximately 320m. Also according to the profile, the maximum elevation in the Sooke Watershed is 841m, and less than 10% of the basin is above 558m.The movement in the watershed would move from the high rides in the north, east, and west, and would drain into Sooke Lake, and then would make its way to the Lake outlet/dam over time. Due to the numerous small streams, it would take some time for the water to make it from the watershed divide, at 841m, to the outlet at dam. Due to the large area of the Sooke Lake, the water in the Sooke Watershed would likely have a relatively long residence time, as water would spend a large amount of time in the lake before making it to the outlet at the south end of the lake, although evaporation is another important factor to consider.5. A 30m resolution will not represent the basin characteristics nearly as accurate as a 2m resolution DEM used in the Sooke Watershed. A 30m resolution will not show nearly as many small terrain features, and therefore when calculating flow direction and flow accumulation there will be much more generalization as to which direction the water will flow and where it will accumulate. Therefore small streams will not be represented nearly as well, and the flow accumulation will be dominated by the larger streams. This can be seen in figure 5, only the larger streams are showing up on the DEM. This can also be seen in figure 7, where the Google Earth image shows many side valleys that would likely contain a stream, and only the larger
