About

The Mareeba-Dimbulah Scheme consists of the Tinaroo Falls Dam, Lake Tinaroo and the Mareeba-Dimbulah Irrigation Area. The dam also supplies the Barron Gorge Hydro-electric Power Station.

How the scheme works

  • Water from Tinaroo Falls Dam is distributed by gravity through 176km of main channel to the various sections of the scheme
  • A further 189km of subsidiary channels distribute water to farms, dwellings and townships
  • Five balancing storages at Nardello’s lagoon, East Barron, Arriga, Biboohra and Jabiru Lagoon ensure effective supply is maintained throughout the system.

Water uses

  • Irrigation water for various fruit, general horticulture, sugarcane, tea-trees and coffee
  • Urban water supply for Tinaroo, Walkamin, Mareeba, Kuranda, Mutchilba, Dimbulah and Yungaburra.

Scheme history

  • The Tinaroo Falls Dam was built in 1952 on the Barron River, 12km from Atherton.

Scheme management

Sunwater aims to achieve the efficient delivery of water to customers in the Mareeba-Dimbulah scheme that best meets their needs.  To manage this water delivery, arrangements for taking of water within the Scheme have been developed in consultation with its Irrigator Advisory Committee.

Tinaroo Falls Dam storage level classifications

The storage level classification must be determined on the first day of each month and applies for the whole of that month regardless of any change in the storage level during the month.

The storage level classification determines the minimum flow volumes required at Barron River at Mareeba and Myola as per Attachment 2 of the Mareeba-Dimbulah Water Supply Scheme Resource Operations Licence.

Month Classification
July 2018 High
August 2018 High
September 2018 High
October 2018 Medium
November 2018 Medium
December 2018 Medium
January 2019 High
February 2019 High
March 2019 High

Taking water from the scheme

The water ordering system assists Sunwater in delivering water to its customers in an efficient and timely way, enabling them to plan and manage their water use.

Before taking any water, customers should place a water order so that Sunwater can release sufficient water and minimise losses.

Customers who take water without ordering may reduce Sunwater’s ability to supply customers who have ordered according to the above requirements.

To place an order

Customers can place their orders via:

Further information about ordering water is detailed in Mareeba-Dimbulah’s Rules and Targets.

Stopping or restricting supply

Sunwater may suspend or restrict supply in a number of circumstances, including:

  • during maintenance of Sunwater’s assets
  • during a peak demand period, when rosters or rations may apply
  • when the demand for water is so small it is impractical to supply it
  • when there is a need to make special releases to maximise efficiency at times of limited supply
  • during rain shutdown
  • infrastructure limitations which make delivery impractical
  • if supply could cause Sunwater to break the law
  • when operating under special notices or regulations issued by the Department of Natural Resources and Mines {e.g. Water Amendment Regulation (No.3) 2006}

Weather events and emergency shutdowns

Sunwater asks that customers notify their duty Water Officer [Link to contacts page], as soon as possible, of any rain event or other circumstances that substantially lessens their water requirements. When wide spread general rain exceeds 40 mm in a day over the Mareeba-Dimbulah Water Supply Scheme, the duty Water Officer may shut the system down.

Customers are also asked to cancel orders if they no longer require ordered water.

For more information contact

If you experience an equipment or power failure emergency, please give immediate notice to Sunwater by calling Sunwater Customer Support on 13 15 89 (24 hours a day, 7 days a week).

Mareeba-Dimbulah’s Irrigator Advisory Committee

The Mareeba-Dimbulah Irrigator Advisory Committee is a group of irrigators within the scheme that have been elected by irrigation customers to represent their interests in relation to scheme operations and water supply issues and improvements with Sunwater.

The committee:

  • provides advice and recommendations to Sunwater regarding scheme operational issues
  • represents the interests of the broader irrigator base in respect of Sunwater’s ongoing operation of the water supply scheme
  • provides a mechanism for Sunwater and its customers to raise and discuss matters of mutual interest in relation to the management of the physical aspects of the scheme and customer relationship issues
  • work collaboratively with Sunwater to identify and introduce new approaches and improvements to water management.

Announced allocations

Water Year: 2018/2019

High priority: 100%
Medium priority: 100% 

Announced Allocations effective 1 July 2018 and will be applicable until revised and communicated by Sunwater.

Carryover Methodology

Maximum Volume of Carryover = 97.5% of the total volume of unused water for the scheme at the end of the water year.

Maximum volume of water that may be carried over by a water user must not be more than 97.5% of their remaining volume at the end of the water year.

(Water User remaining volume x 97.5%) x 100% x 85%

Customers are advised to obtain information about their remaining water allocation balance by accessing SunwaterOnline.

For more information or enquiries, phone 13 15 89 or email customersupport@sunwater.com.au.

Water pricing

Sunwater reviews bulk water pricing for each supply scheme every three years.

The Queensland Competition Authority (QCA) is responsible for recommending rural irrigation prices charged by Sunwater. QCA recommendations are considered by Sunwater’s shareholding Ministers, who together make the final decision and set Sunwater’s rural irrigation prices.

Fees and charges

Each year Sunwater releases an updated fees and charges schedule for water supply schemes, detailing the charges set by Sunwater and those subject to the Rural Irrigation Water Pricing Direction. For information on the most recent fees and charges for the Mareeba-Dimbulah scheme, please refer to the documents below.
