CQ cotton growers face dismal water allocations

FOR the first time in a decade, Central Queensland irrigators and growers are facing the prospect of grim water allocations.

SunWater released their water allocations for the 2018-19 season following final calculations across its 31 water supply schemes.

As of yesterday, Fairbairn Dam was sitting at 20 per cent capacity - and the allocations for the Nogoa-Mackenzie scheme reflect this dismal water amount.

An allocation of 6 per cent was given to medium priority customers and 100 per cent for high priority customers.

Water allocations indicate the percentage of an irrigation customer's purchased water entitlement expected to be made available for use within a water year.

The figures are calculated on the amount of water in storage combined with variable factors such as evaporation, seepage and use.

SunWater chief executive officer Nicole Hollows said she was committed to working closely with irrigators in schemes with low allocations to ensure they remained well informed about available water supply, given more than half of Queensland was drought declared.

"We understand the significant pressure low allocations across some schemes are having on customers' business," Ms Hollows said.

"We will work diligently to determine rostering and scheduling systems for irrigators in these schemes to ensure water is delivered in a way that minimises loss and maximises availability.

"Announced allocations will also be recalculated at regular intervals throughout the water year to take into account any additional inflows."

In Nogoa Mackenzie, SunWater will begin a major water efficiency project this year to help reduce water losses by up to 6000 megalitres per annum.

Ms Hollows said the works aimed at maximising available water volumes and they would work with customers to find innovative ways to improve water availability.

"The $11.7 million Nogoa Mackenzie project received a funding contribution of $3 million from the National Water Infrastructure Development Fund and will help minimise water losses through re-lining 34 kilometres of channel," she said.

The last time Fairbairn Dam was around this level was in December 2007.

Since construction of the dam was completed in 1974, the lowest volume the dam reached was 11.8 per cent (152,940ML) in December 2006.

GROWERS POSITIVE, DESPITE GRIM WATER NEWS

DESPITE extremely low water allocations for this season, Central Highland growers are remaining positive.

Central Highlands Cotton Growers and Irrigators Association President Aaron Kiely spoke on behalf of 40 growers and 50 associate members in the group, stating they were well prepared.

Membership is comprised of grower/irrigator members who grow crops that include cotton, mungbeans, soybeans, sunflowers, chickpeas, wheat, grapes, melons, and citrus.

Associate members include product resellers, bankers, agronomists, consultants, contractors, ginners, merchants and researchers.

"Growers remain optimistic about early rainfall to produce inflow into the dam which could lead to an increase in announced allocation," Mr Kiely said.

"There is no significant spring rainfall predicted at this stage."

The announced allocation from Fairbairn Dam has been "very reliable over a number of years" which irrigators are hopeful will continue, he said.

"SunWater had been providing projected allocation updates in the lead-up to the end of the water year," Mr Kiely said.

"Growers were expecting a reduced allocation and planned their production accordingly."

Cotton is a main source grown in the region, along with citrus and macadamias which have recently expanded in the region.

Planting for cotton began this week, Mr Kiely said.

"Growers have the opportunity to plant cotton until the end of December," he said.

"While the cotton plant has begun, there is still plenty of field preparation happening for the upcoming season.

"There will be reduced cotton planting hectares in the region as a result of the lower announced allocation."

This year will be a stark comparison to successful previous seasons, Mr Kiely added.

"Last season saw some excellent yield and quality results across the area," he said.

"This was the result of favourable weather conditions and a pleasing cotton price."

He said other growers are working out their plans on what they will do this year.

"Growers are making decisions to reflect the current allocation, however they arfe still preparing for opportunities throughout the coming season," Mr Kiely said.

"They will be making planting decisions based on their announced allocation and their carry over water from the previous season.

"Growers will still be prepared for planting opportunities later in the season should there be a local rainfall event or inflow into the Fairbairn Dam.

"There is no doubt that irrigators will be hoping for a wet start to the spring/summer season."

GROWING CYCLE:

  • Aug - Sept: Farm and soil preparation
  • Oct - Nov: Planting
  • Dec - Feb: Growing season
  • March - June: Harvesting
  • July - Aug: off-season
  • New technology has allowed for cotton to still be planted in November and December.
