The sea, once it casts it’s spell, holds one in it’s net of wonder forever – Jacques Ives Cousteau
Diving in The Netherlands. I can hear you thinking. What? Where? Is there anything there? Yes, we have our lovely pea soup as we call it. Cold, dark, green waters, full of algae and thus life. There is a rather large diving community. Mostly Dutch and Belgian, sometimes even a few Germans. And me. How come?
Once upon a long long time ago. I was traveling in East Africa, Malawi to be precise, where somebody told me it was cheap to get my PADI certification. I am Dutch, so why not. I did my training in the large Lake Malawi and logged a few dives at Zanzibar some weeks later. And that was it. Years later, at the Poor Knight Islands in New Zealand, I went diving again. After being close to panic, I realized that without practice I would not enjoy diving. So I decided to go for my advanced certification close to home in a sand pit. Guess what, I got infected by the scuba virus. I was amazed by the many life forms I found under water, even with our mostly poor visibility. I kept on diving, became a Dive Master, attended some biology trainings and I started to check off as many creatures as possible, enjoying almost every dive I did. Almost, because diving in The Netherlands is not easy. Sometimes the waters were so murky that I lost my buddy, or weather was too bad to enter the waters safely. But, to be honest, I logged hundreds of dives in these waters. There surely are some really nice places for diving, each with their specific life forms.
The Netherlands has many lakes, all basically divable, but some have special facilities available. Think: toilets, parking, easy shore access, scaffolding and sometimes ladders, but most important food and beverages. I have been diving in some lakes like Oostvoorne, Vinkeveen & Spiegelplas. Especially in Spring, when the water is too cold for the algae to bloom, visibility is acceptable and you can see many animals waking up. Small Crayfish, Eals, Perch and small, but also very big Pike. Fresh water diving is not so much the flora and fauna as it is what we humans have dumped in the waters. Boats, tires, busses, construction waste. A lot of pollution, but also hiding places for fish. It is always a pleasure to explore. And difficult, for the compass cannot handle all the iron under water very well. Navigation skills are key in our country.
The Grevelingen Lake is a large water area just south of Rotterdam. It used to be a sidearm of the North Sea, but due to the damming activities (Delta Works) for protecting our land, it was closed with two dams in 1965 and 1971. The largest salt water lake in Europe was born. Locks in both the Grevelingen dam and the Brouwers dam manage the salt level. Even though man intervened, the underwater flora and fauna found it’s way to flourish. It is an easy place to dive, even though navigation skills are still necessary and waters can be murky and dark. Maximum depths at dives are up to around 30 meters, but below 15-20 meters life is scarce. Some of the nice things to see are huge lobsters, crabs, all kinds of small fish, jelly fish, anemone, sponges, algae and some nudibranches. Very rarely there are sightings of porpoise and seals. In some locations artificial reefs have been placed to create hiding places for wildlife, and thus can be very interesting for divers. Even though divers have to climb with all their gear over the dikes which are protecting the land, the dives usually are very rewarding and facilities at the dive sites are great. Surely a good dive does not stand without some after dive drinks and food at one of the nice restaurants in the small, mostly pictureque towns around.
For me personally the nicest dive spots are in the Oosterschelde. Again a closed sea arm of the North Sea, closed by a storm surge barrier in 1986. It is not completely closed, the dam has sluice gate type doors which let water flow freely, until a storm and extreme high tides are predicted and the doors are closed. The flora and fauna can enter any time, making the diversity somewhat larger compared to the Grevelingen lake. Seals, dogfish even porpoise can been seen under water, but there is much more. In some areas large groups of sponges are making colourful scenes, more than 50 species of nudibranch can be found, large groups of sea bass and mullet are roaming the pillars of bridges and, my personal favourite, cuddlefish and squid are mating and reproducing in Spring. Every season has its active species ready to be found and admired. There are some hanging mussels which are accessible for divers. Amazing how good visibility is around these large numbers of ‘filters’.
Diving in these waters always depends on season, temperatures of the water, weather, tides, currents and number of divers. Anything can influence the conditions and visibility. But once I knew how it worked, I really loved diving here.
Diving: take nothing but pictures, leave nothing but bubbles.
