Yesterday, the Taieri River dipped below its minimum flow levels at Outram and did the same at Waipiata at the weekend.
This means irrigators cannot take water in those areas.
Mr Wilson said while it was a very dry summer, most farmers had good feed reserves from last year.
"We came into spring with good soil moisture levels. The stock have done well.''
When rivers dropped below minimum flow levels it "really put a strain'' on farmers, he said.
That was why the company was investigating options for increasing water storage at the Loganburn Reservoir, he said.
La Nina weather patterns were also predicted by some to bring rain around Christmas, he said.
"We live in a dry area. You have to be optimistic.''
The Taieri River last hit its minimum flow levels in 2015.
Otago Regional Council environmental monitoring and operations director Scott MacLean said while many Otago rivers were low, the Taieri was the only one to hit its minimum flow levels.
This was due to the current spell of dry weather, combined with little snow cap to augment river levels from snow melt, he said.
Over the last few dry seasons, the community worked together and managed the water resource "very well'', he said.
"Every water take influences flows and, if carefully managed, such as that happening in the upper Taieri, the environmental gains from the voluntary rostering efforts are maximised.
"If the community works together to manage water responsibly, the vulnerable river ecology will be protected.''
