DCC UPDATE - December 2008

The surveys and investigations scheduled for Ocean Beach in 2008 are now complete.

A full topographical survey has been completed, together with a bathymetric survey. The automated Cam-eras are running, and the pictures from them should be available for viewing though the NIWA website. Tenders closed on 12 December for Hydrodynamic Modelling, which is the study into such elements as wave refraction, sediment transport, and the effect of storms on the beach. This will be part of the further research into the dynamics of the beach in the New Year.

There has also been good progress with a series of Focus Group meetings with the key stakeholders, and these will continue into 2009.

As these studies progress and the information base grows, the Council will continue to liaise with the Otago Regional Council and the Department of Conservation to identify the best solution for the Ocean Beach.

As previously advised, the results of these studies will form part of a draft plan for the Ocean Beach which will be fully consulted with the community before it is formally considered by the Council.

Ocean Beach 100 years Ago

The Ocean Beach is a scene of incessant warfare between land and water, and an annual inspection of the frontier of silver sand shows to what extent one or the other has prevailed.

The Ocean Beach possesses remarkable characteristics, one of which is the undertow that makes it such a dangerous place to bathe from, and incidentally shifts so many tons of sand.

For this the tremendous inrush of billows to the Brighton Bight is mainly responsible.

The heaped-up waters find an easy egress by the narrow channel between White Island and Forbury Head, through which they pass at the rate of three miles an hour, thus causing a scour, which, though felt most severely at St. Clair, affects the whole foreshore right down to Lawyer's Head.

Were it not for the Ocean Beach Domain Board, a high spring tide, accompanied by a heavy gale from southerly, might result in a flooded St. Kilda.

A buffer has been found in the sand, swept to and fro by the sea and blown about in clouds by every wind.

Not a very stable material but with a little ingenuity and a great deal of perseverance the Domain Board has succeeded beyond expectations.

Scrub fences were erected to act as revetments, and the sand drifted and covered them, precisely as it blotted out the cities of the Pharaohs.

More fences were made and in turn covered, and the coarse, hardy sand grass, spreading and growing steadily, served further, as it were, to bind the compact.

• A strong, respectable-looking man came before the Benevolent Trustees yesterday, and, with the homely burr of Scotland, asked for aid.

He was 30 years of age, was married, and had been employed as a warehouse measurer in Glasgow.

Times were bad there, and he had scraped together enough money to pay his passage to New Zealand.

Having had experience of work in woollen mills, he applied at the Oamaru, Roslyn, and Mosgiel mills in vain.

On Monday he had walked in from Mosgiel, after having spent Sunday night in a stable, and was now literally starving.

He broke down then, and the big manly frame, weakened by hunger and the long, vain search for work and independence, was shaken with weary sobs.

The trustees promised him immediate help, and sent him off with a coin, cheered and grateful, to buy himself a good square meal. - ODT, 10.12.1908.

Perego's Lagoon




It was a foggy Sunday afternoon and we could barely see the beach from the trail along the top of the bluff. On a nice day, the views from this spot on the west side of Whidbey Island are spectacular. It was nicer weather last February (Perego's Lagoon), although I didn't get to the north end on that trip. This trip left me wanting to come back and spend more time checking out the lagoon itelf, particularly the washover fans and what appear to be small marshy barriers inside the lagoon.

The ridge that separates the northern portion of the lagoon formed sometime between the late 1970s and the early 1990s (the 1979 storm that took out the Hood Canal Bridge may be the best candidiate), but as recently as last winter was the site of additional washovers. There are several more fans on the back side of the barrier along its central section, though none extend as far across the lagoon as this one.
The beach - typical of the western shore of Whidbey - is a wonderful mix of gravel and sand in patterns that are sometimes rhythmic and sometimes not.
