We take raw water from a number of sources, and our two main storage reservoirs at Whau Valley and Wilsons Dam ensure continuous supply during even prolonged dry spells.

Two other dams, the Gomez Dam at Hikurangi and Takahiwai Dam at Ruakaka, are not currently in use but are available in emergencies.

Whau Valley Dam

Whau Valley Dam holds 1,871,286 m3 of water and supplies Whangarei City and its surrounds.

The catchment area also has recreational value and management of it is included in our reserve management plan for Pukenui Forest.

  • Boating and swimming are not allowed at this dam.
  • Dogs must be kept on a leash around the Whau Valley Dam as young kiwi have been released into the area.

Wilsons Dam

Wilsons Dam holds 2,491,730 m3 of water and supplies the Bream Bay area. 

  • Boating and swimming are not allowed at this dam.

Water level alerts

The water levels in these reservoirs rise and fall through a normal year, and the quantity of water together with the time of year are used to calculate the 'Alert' level shown in the table below.

If the alert colour moves to amber or red, we will update this website with any measures or restrictions that are put in place.

Please do not eat fish, swim or allow dogs into the water at Wilson's Dam or Whau Valley Dam.

Fill the Dam!

The first half of 2020 saw troubling water-shortages and water-restrictions up to Level 3. Although formal restrictions have been lifted, our new challenge is to fill the dam and prevent further issues in 2021.

Be Water Wise website

Our dams are designed to fill up during winter time, but low rainfall over the last 2 years has lead to very low water storage levels. Even during rainy times it is important to save water at home and at work.

Top 6 smart water conservation tips

  1. Wait until you have a full load before you turn on the dishwasher or washing machine.
  2. Turn the water off while you are brushing your teeth.
  3. Keep a jug of drinking water in the fridge and keep it topped up. If you run the tap long enough for water to cool down it can waste 10 litres a minute.
  4. Apply the 'step test' to the lawn – if grass springs back after you walk on it, it doesn't need watering.
  5. If your toilet has a dual-flush button, use the half flush and think twice about whether you really need to flush.
  6. Let the car go dusty – let it show what a conscious water conserver you are.
