preservation of wet season flow may be a viable, though costly (because the high regional evaporation rates which demand deep storages) alternative. 4.4 Gully Dams Gully (embankment) dams across creeks, are the most versatile of all farm reservoirs, and are generally used for irrigation water storage in gently undulating country. It should be noted that structural failures are high amongst gully storages, as they require a high standard of design, construction and management. In general, in a pastoral situation, gully dams are built on a rock foundation as a last resort and at very high cost. Though the terrain over much of Waterloo is gently undulating to hilly, the construction of these dams is generally not considered economical because of the hard rock (basalt or sandstone) foundation, and high evaporation rates. This option is generally outweighed by the presence of groundwater (relatively unaffected by evaporation) from good aquifers in these rock types. The basalt and sandstone are very difficult materials to excavate for the purpose of providing a good seal in the embankment area, or to provide a spillway for excess runoff. Leakage due to jointing in the rock may also be important in some areas. Similarly costs of importing large volumes of impermeable material (eg. blacksoil) for embankment core construction may be high in some areas. The minimum average depth of a gully storage in Waterloo should be about 5 m to compensate for annual evaporation rates of about 2.4 m. Embankments of more than 3 m high will need to be licenced with Water Resources Division. They are not generally recommended for surface warter storage on Waterloo Station. However, should these dams be required for irrigation purposes it is recommended that the advice of a geotechnical or civil engineer is sought. 4.5 Recommended Surface Water Storage Types The excavated tank type of surface water storage is suitable for the flat country in the floodplains of West Baines River, with hillside storages being the preferred type in the shale and cracking clay country with moderate slope. The recommended minimum depth for the excavated tank is 5 m. The reliability of the tank is determined by the depth of the stored water. Three types are suitable for the floodplain area, these being onstream, off creek, and tanks excavated in a drainage area without a clearly defined creek system (hereafter called simply an offstream tank), the latter being the preferred option. The onstream excavated tank requires a high standard of design and construction and is prone to erosion or silting. The off creek design uses a manmade channel to divert water from a
