Limited and costly availability of water had dismissed any hopes of farmers sowing summer crop seeds.

But sufficient rainfall in recent years has built high expectations for the seasons ahead as many farmers sow their first summer crops since 2001.

Jemalong Irrigation chairman Stuart French said there were eight or nine growers giving it a shot this season within the Jemalong Irrigation District.

"Two are growing rice, four growing maize and I think three growing cotton," Mr French said.

Despite more rainfall received than expected the quality of the crops on his Forbes property "Manna Station" has not at all been compromised.

"The maize, with the milder summer, looks very good," he said. "As wet as it has been we've saved probably three or four irrigations."

With 150ha or maize in this year, Mr French dismisses any concern about the extra rain affecting the crop.

"It (the rain) wouldn't have had any detrimental yield impact on the maize," he said. "It has an upside but it certainly hasn't had a downside."

To encourage more growers in the Jemalong Irrigation District to incorporate summer crops into their operations again, a summer crop field walk will be run on February 23.

:We are holding a summer crop field walk to try and get people to come out and have a look at what you can do and to show that there are options out there for summer crops," Mr French said. "There's no need to be daunted by it."

While extra water supply is good news, it is also a cause for concern for the Lachlan region.

"One of the biggest issues coming out of the (Murray-Darling) Basin Plan and water reform in general is the inequity of it," Mr French said.

Jemalong Irrigation has so far been unsuccessful in two tenders made for infrastructure upgrades through the Private Irrigation Infrastructure Operators Program.

"It appears to us that there's a fair bit of inequity in how they're allocating resources for infrastructure upgrades," Mr French said.
