Figure 43). Prior to the Nimmie-Caira water action Eulimbah Swamp and Waugorah Lagoon were mostly dry while Telephone Creek was about 60% inundated. Waugorah Lagoon was inundated to 60% of its wetland extent in December 2015 and then contracted to less than 20% by January 2016. Eulimbah Swamp was fully inundated by late November-early December 2015 also inundating the adjacent floodway downstream at this time. Eulimbah Swamp remained mostly full until late March 2016 and so inundation duration was about four months. Telephone Creek remained mostly (>85%) full from November 2015 to late April 2016 and so inundation duration of this area was for about five and a half months. Yanga National Park (Redbank zone) Commonwealth environmental water was delivered using the most direct flow path to Tarwillie Swamp and so from the pre-watering extents (~2000 ha) there was only a small 300 ha expansion of inundated area to about 2,300 ha on 1 December 2015 (Figure 44). This expansion was confined to the flow path region in North Yanga around the east of Two Bridges and in Two Bridges Swamp, which then started receding by mid-January and was dry by March 2016 (Figure 43 and Figure 44). Adjacent wetlands (e.g. Piggery Lake) were not inundated by this watering action and were able to dry out over summer (Figure 43 and Figure 44) having been inundated for over 12 months (since late November 2014). Inundation extent in Tarwillie Swamp remained about the same as the pre-watering extents (~150 ha) through November to January and then started to recede in February 2016 until it was dry by April 2016 (Figure 44). By mid-January 2016 about 80% of the 150 ha of Tarwillie Swamp had been inundated for just over 12 months (since late November 2014). Overall the total area of floodplain wetland inundated by the Yanga National Park action was 2,555 ha.
