* Catchment rainfall is the average of rainfalls recorded in and around the dam catchment.

** On 21 January 2016, temporary full supply levels were enacted for Somerset Dam and Wivenhoe Dam (part of the Somerset Dam Improvement Project). These equate to storage percentages of approximately 80% for Somerset Dam and 90% for Wivenhoe Dam. These temporary full supply levels will remain in place until current dam improvement works at Somerset Dam are completed. Seqwater will commence flood releases from Wivenhoe and Somerset dams if storage levels exceed the enacted temporary full supply levels as a result of rainfall in the dam catchments.
