Blitz the beach

Community member Sally asked me to spread the word, and I think she’s right:

The tides have delivered a bumper crop of plastic rubbish (so many plastic bags!) onto the beach in the past few days. This gives us the chance to grab that plastic before it gets swept back out into the oceans.

So, if you’re heading to the beach for a walk in the next few days, do take a bag or sack for a bit of plastic rescuing while you’re walking and you’ll get to feel good about doing a favour to our oceans, our wildlife, and our food chain.

The photo shows a small part of rubbish I picked up the other day — mainly plastic, but also foam cushion, cans and other junk. A lot of locals pick up rubbish from the beach from time to time, but we definitely need to blitz it at the moment. All hands on deck!

High tide and a full bay on 03 August 2019

Stephen Betts kindly sent in these two panoramas showing a very full bay at high tide on 03 August 2019. Sea water was at times lapping at the base of the Manga Pirau Street entrance, had swamped the bar encroaching from the north side and had even cut the corner on the south side beach.

Dune planting report, and groyne change photos

Local Stephen Betts has recently been taking photos of the dunes and the river mouth groyne. He’s kindly allowed us to publish them, with his commentary.

Two pictures of the Waikawa river groyne approximately 1 month apart, 2019-06-30 (Low Tide) and 2019-07-27 (Low tide).

River mouth photo 20 July 2019

The drone photo of the river mouth, taken on 20 July 2019, shows the effect of removing the high-angle groyne.

Blair, who made the image, said:

The area near where the river enters the sea – could not be rendered as it did not have enough cross reference points to match on. Active water bodies are notoriously difficult to produce aerial imagery.

Always best to fly for photos at low tide.

[This photo] does show the difference in the rock walling and where the channel funnels out to sea.

River mouth update 20 July 2019

We’ve had a bit of rain and some high tides lately. The other day the river was very full, but it hasn’t had a lot of power. We need the right conditions to give it a full-flood flow so it can flush out sediment.

The work on the groynes seems to have improved how the river flows into the sea though. It flows past the groyne that was built up and then turns south, but only slightly. It’s currently flowing reasonably directly to the sea, well away from the land.

First seal pup of 2019

Spotted on the beach today, coming down off the dunes: the first seal pup of the season.

Please watch your dogs on the beach, and drivers beware. Remember, the law says you must stay at least 20 metres away and it’s an offence to disturb, harass, harm, injure or kill a seal. See Seal safety at Waikawa Beach.
