EstuaryWatch Data Portal

AHD posts removed due to planned bridge replacement. Water level high, almost up to jetty. No sandbank.

Wide estuary mouth, narrow river outflow channel

Large clump of ?reeds ?seaweed in lagoon

I forgot to record tide heights

Access track partially underwater

Mouth closed but an illegal opening occurred on 19-03-20 which created some outflow out for a short period before the channel closed up again by early am 20-03-20

About .30m of last rock above water level at start of river

Water over increased area of top track, low track has water up to ocean car park. Campground has no visible water but very small puddle on north side of OCR before bridge. No water visible on G.O.R.    Small area of shallow water flowing from river is travelling north across OOR  - vehicle access was still possible

Observation taken @ low tide

Sand height has increased between mid beach & mouth. Beach shape has changed, higher @ mid beach with broad projection extending slightly out to sea, while area towards mouth is higher - the area to east is lower & undulating. A sandbar is running parallel to shore about 40m. out, starting from the projection & continuing close to mouth

Upstream flats up to G4 are starting to flood . No water over OOR nor in area upstream G4 apart from small area between G5& G4

Observations made @ Low tide

River perched-some waves going up into river with return to ocean. Waves occasionally overtopping all along beachfront. Previous very rough seas have over topped beach front & travelled down wide shallow depression behind  entering river channel on both sides of rocks - action of backwash to ocean has reduced height of beach front near mouth & created a very low gradual rise up to the start of the river

Seal on Princetown beach 02-03-2020

Reducing outflow carrying a large amount of sand. Then travelling  along foreshore to east Also lighter discharge going to west.Height of beach from mid beach to mouth has increased but from mid beach where it is highest to east the end  it is much  lower. Waves from last high tide have been overtopping & travelling along a wide shallow depression to enter channel around rocks. Sheer east side to channel near mouth indicates a strong flow at last change of tide
