Underwater Inspection at Lake Attersee — Clear Water, High Visibility Advantage
Lake Attersee, with 46 km² and a maximum depth of 169 m, is the largest lake located entirely within Austria. Its exceptionally clear water allows optical inspection down into deep areas. ScanSustain inspects jetties, boathouses, landing stages, gauge structures and deeper-lying infrastructure ROV-based.
Characteristic Structures
These structure types can be inspected ROV-based at Lake Attersee — subject to approval from local authorities and operators:
Ship landing stages
Landing stages of the Attersee shipping line (Attersee, Weyregg, Steinbach, Unterach, Nußdorf, Seewalchen). Inspection of berth edges and bed area.
Gauge structures
Gauges of the Upper Austrian Hydrographic Service. ROV survey of the gauge board, pressure-sensor installation and cable-bound transmission.
Anchor structures for buoys and navigation marks
Boat anchors, lake marker buoys, floating jetties with anchor stone. Findings capture of anchor position, anchor sinking into sediment, and chain/rope wear.
Typical Damage Patterns
What can be professionally captured at Lake Attersee — a structured overview of the locally typical damage patterns:
Timber-pile damage patterns
Support piles of larch and oak: fungal attack in the zone of fluctuating water levels, bore holes (wood-boring insects), pile drift.
Algae growth on jetty substructure
Seasonal algae growth layers. Findings with quantity and distribution capture.
Sediment accumulation at the gauge
Gauge structures accumulate fine sediment, which can affect measurement accuracy. Structured capture as a basis for maintenance planning.
On-Site Methodology
Lake Attersee's water is among the clearest in the DACH region (visibility up to approx. 8 m, more seasonally). ROV optics can be deployed everywhere, including in deeper areas. Sonar serves as a complementary method for structured depth profiles and large-area surveys. Deployment window all year round, deep inspection preferably in the cold season (clearest visibility).
How Deep is Lake Attersee?
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
169 m. ROV systems cover the entire depth range.
Lake area
Around 46 km² — the largest lake located entirely within Austria.
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 Lake Attersee
Beyond pure condition inspection, municipalities, port operators and engineering offices at Lake Attersee are increasingly asking for geometric data — for example for the rehabilitation planning of landing stages, the as-built documentation of jetty facilities and boathouses 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 Lake Attersee, the exceptionally clear water quality (visibility up to approx. 8 m, more seasonally, see On-Site Methodology) enables particularly good photogrammetric detail capture; multibeam sonar complements this with structured depth profiles and large-area surveys, also in the deeper areas of the lake. 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
Upper Austrian Hydrographic Service (gauge infrastructure). Water-rights authority Bezirkshauptmannschaft Vöcklabruck. Municipalities of Attersee, Weyregg, Nußdorf, Seewalchen, Unterach, Steinbach am Attersee. Nature-conservation authority for ecologically sensitive shoreline areas.
Frequently Asked Questions
How deep does the ROV inspection at Lake Attersee go?
Lake Attersee has a maximum depth of 169 m. Our ROV systems reach depths far beyond that. For typical jetty and landing-stage inspection, working depths are 1 to 12 m.
Can we follow the inspection live?
Yes. On site, the client can view the live video on the operator screen and discuss findings directly. Recording takes place in parallel.
How long does a jetty inspection take?
Typical deployment duration per jetty: 1–2 days including evaluation. More complex boathouses and floating-jetty facilities take correspondingly longer.
Does ScanSustain also offer survey and 3D mapping at Lake Attersee?
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 Lake Attersee require official approval?
As a rule, yes. The responsible bodies are the water-rights authority Bezirkshauptmannschaft Vöcklabruck and the affected municipalities of Attersee, Weyregg, Nußdorf, Seewalchen, Unterach and Steinbach am Attersee; for ecologically sensitive shoreline areas, additionally the nature-conservation authority. We clarify responsibility in advance together with the client.
How does Lake Attersee's clear water quality affect the ROV inspection?
Lake Attersee is among the clearest lakes in the DACH region (visibility up to approx. 8 m, more seasonally). These visibility conditions allow optical ROV inspection even in the deeper areas of the lake, which is up to 169 m deep; sonar complements the capture for structured depth profiles and large-area surveys.
