Detailed examination of the proposed dam site on Smith Creek has shown it to be suitable for either a concrete or earthern dam of the height proposed. The rocks in the main foundation area and both abutments are hard tough siltstones and sandstones. They have been affected by weathering to only a shallow depth, necessitating some excavation for the foundations. No faults were observed but the rocks are cut by numerous joints which require treatment by grouting, chiefly in the main foundation area, to minimise leakage. A suitable site for a side spillway is available or the excess flow could be spilled over the top of a concrete dam if such is built. Some of the materials of construction are available close to the site.
