The first process in facing up to a season without water is to set some rules and make certain assumptions. Assumptions can be based on previous experience, fact or fiction and can incorporate any degree of risk. In essence, its a question of looking at the known e.g. available land, water currently available from the dam and on farm storage, then taking a position in respect of future outcomes. For example, expected average rainfall, (more or less) and the likelihood of future irrigation water from storage and surplus flows. Then, you need to provide enough flexibility in the system to take advantage of changed circumstances and opportunities.
