By the numbers

Haarlem by the numbers what the water holds.

84 km: of waterway on our Haarlem map
212: bridges mapped
2: locks
92: bridges with an official clearance

Key findings

What we found

92 of 212 bridges publish an official clearanceThe other 120 show as unknown: no authority publishes a height for them, and we do not estimate one.

Honest about limits

What we do not have for Haarlem yet.

Places to stopWe check every place by hand before it goes on the map, and Haarlem has none published yet.
Water levelHaarlem's water is part of Rijnland's boezem (the regional storage water), held close to NAP −0.61 m in summer and −0.64 m in winter. Published bridge clearances assume the normal level, so read the height board at each bridge before you go under.

Waterways

Haarlem's waterways every route follows them.

Floating Today maps about 84 km of waterway in 141 segments on our Haarlem map, which reaches beyond the city into the lakes and polders. Every route in the app is drawn along these lines.

Data and methodology

How we built it from official data to this page.

Source
Official figures from Rijkswaterstaat, EuRIS and the City; waterways and bridges from OpenStreetMap.
Curate
Every place to stop is checked by hand: where to tie up, what is allowed, what is there.
Calculate
Every count, share and distance on this page is calculated from the data above.
Show honestly
Where a figure does not exist, we say so rather than estimate one.

Coverage: Haarlem
Last checked: No dated source read
Updated: Notices, lock data and swimming status daily; places to stop as we check them; waterways and bridges with each release
About the data: Bridge clearances, lock data and notices are official figures, shown as published. Waterways and bridge positions come from OpenStreetMap.
What we add: The places to stop (curated by hand), and every count, share and distance on this page, which Floating Today calculated from the data above. Where a figure does not exist, we say so rather than estimate one.

We do not smooth, model or forecast any figure. Read the board at the bridge, the lock or the quay before you rely on a number.
