Description / Abstract: Stream flow and water quality measurements were made along the reaches of the Katherine and Daly Rivers in October 2014. The flow increases progressively downstream with a maximum flow of 29.8 cumecs measured in the Daly River at Mount Nancar. The results illustrate the contribution of flows from the different aquifers and sub catchments relative to the total runoff in the Daly River. The October 2014 stream flows are well above the average annual minimum flows from 1961 to 2013 at the primary monitoring locations. The stream flow measurements do indicate that October flows have been steadily decreasing since 2011. Recharge patterns identified during this October 2014 exercise, support similar trends seen in previous end of dry monitoring exercises, conducted in October 2009 and 2013. For the first time groundwater levels were also measured at a number of locations during this exercise. Aim: Late dry season snapshot measurements were undertaken on the Katherine and Daly River to establish water quality and quantity conditions at the end of the dry season when river flows are at their annual minimum. Snapshot measurements are used to: 1. Refine and calibrate hydrological models used to assess resource availability and impact of extraction allocations. 2. Verify model predictions at key river locations used for announced allocations on 1st May each year. 3. Refine the location of aquifer recharge/discharge zones along the river, and 4. Provide a dataset of comparable flow and water quality measurements at identical periods in the annual water cycle.
