Historically the creek section was likely perennial (due to refilling from ground water springs), but farm dam abstraction has resulted in these pools now receiving only intermittent surface water flow. This is most apparent in dry years, and over the last 5 years there have been critical water shortages in this section of Rodwell Creek. In fact there were no surface water flows in 2007 and 2008, and subsequently receding water levels over summer and autumn seasonally threatened this River Blackfish population. During summer and autumn, lower water levels had decreased habitat area and disconnected the standing water from emergent vegetation, and dissolved oxygen concentrations had diminished considerably. These deteriorating conditions have prompted emergency invention (since autumn 2008) that has involved environmental watering and aeration, on the regional basis, of the main River Blackfish refuge. These management actions have ensured the short-term survival of River Blackfish, as it was predicted that Rodwell Creek would have completely dried in 2008. In 2010, the creek experienced flow conditions, which subsequently increased flow and water levels and connectivity through the section. Encouragingly, significant recruitment and expansion in population size and local distribution were realised in response these improved flow conditions.
