Underwater Inspection at Zeller See — Pinzgau, tourism centre
Zeller See in the Pinzgau region (Salzburg), with 4.6 km² and a maximum depth of 70 m, is shaped as the tourism centre of Zell am See by dense hotel infrastructure, landing stages and lido facilities. ScanSustain inspects the entire lake depth ROV-based. Actual deployments are subject to approval by the responsible local authorities, facility operators and shipping administrations.
Characteristic Structures
These structure types can be inspected ROV-based at Zeller See — subject to approval from local authorities and operators:
Hotel jetties
Dense hotel infrastructure in Zell am See, Thumersbach. Findings capture of timber, steel and concrete components.
Lido facilities
Municipal lido facilities with jetty and platform structures.
Gauge infrastructure
Gauges of the Salzburg Hydrographic Service.
Typical Damage Patterns
What can be professionally captured at Zeller See — a structured overview of the locally typical damage patterns:
Timber-pile damage
Support piles: fungal attack, insect infestation, pile drift in soft sediment layers.
Algae growth
Seasonal growth layers.
Sediment deposits
Elevated sediment accumulation in the area of the South Bay and at landing stages.
On-Site Methodology
Zeller See water is clear (visibility 2 to 4 m). ROV optics primary, sonar for structured bed capture. Deployment planning outside the tourism peak season is preferred.
How Deep is Zeller See?
For method selection in ROV deployments, the lake's depth profile is decisive: near-shore structures such as jetties, landing stages and lido facilities typically lie in the range of 1 to 10 m, while the lake drops off markedly towards the centre.
Maximum depth
70 m maximum. ROV systems cover the entire depth range.
Lake area
Around 4.6 km².
Mean depth and the exact position of the thermocline vary by source and season. For projects with accuracy requirements we recommend verifying these values in advance against a current hydrographic source — we do not take them as given unchecked when planning a deployment anyway.
Survey & Mapping at Zeller See
Beyond pure condition inspection, municipalities, hotel operators and engineering offices at Zeller See are increasingly asking for geometric data — for example for the rehabilitation planning of landing stages, the as-built documentation of high-quality hotel jetties or the bathymetric mapping of shoreline sections ahead of a construction project. With Survey & Mapping, ScanSustain offers photogrammetric and multibeam-sonar-based capture that delivers depth profiles, site plans and 3D models in CAD/GIS-ready formats.
At Zeller See, the clear water quality (visibility 2 to 4 m, see On-Site Methodology) enables a good combination of optical detail capture and multibeam sonar for the surface geometry. This combination is particularly relevant for gauge structures, berth edges and larger jetty facilities when a geometric baseline is needed for rehabilitation or monitoring.
Regional Authorities and Bodies

Frequently Asked Questions
How large is Zeller See?
4.6 km² area, 70 m maximum depth.
Are inspections possible during the peak season?
Yes, with a longer lead time. Outside it (April, October, November) it is logistically simpler.
What is a typical mobilisation time?
From the Burgkirchen base, 1.5 to 2 hours' drive.
Does ScanSustain also offer survey and 3D mapping at Zeller See?
Yes, as part of Survey & Mapping — currently as a pilot service, with photogrammetric and multibeam-sonar-based capture for depth profiles, site plans and 3D models in CAD/GIS-ready formats.
Does an ROV deployment at Zeller See require official approval?
As a rule, yes. The responsible body is the water-rights authority Bezirkshauptmannschaft Zell am See (district administration), together with the affected municipalities of Zell am See, Schüttdorf and Thumersbach. We clarify responsibility in advance together with the client.
Which damage patterns are especially common at Zeller See?
Besides timber-pile damage patterns (fungal attack, insect infestation, pile drift in soft sediment layers), Zeller See shows elevated sediment accumulation in the area of the South Bay and at landing stages. The clear water quality (visibility 2 to 4 m) supports the optical findings capture.
