Underwater Inspection at Lake Ammersee — Bavaria's third-largest lake
Lake Ammersee, with 47 km² and a maximum depth of 81 m, is Bavaria's third-largest lake after Lake Chiemsee and Lake Starnberg. Landing stages of the Bavarian Lake Shipping, hotel jetties and lido facilities generate a regular inspection demand. ScanSustain inspects ROV-based up to the maximum lake depth. 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 Lake Ammersee — subject to approval from local authorities and operators:
Hotel and private jetties
Hotel and private jetties. Condition assessment of timber, steel and concrete components.
Lido facilities
Municipal lidos. Inspection of jetty and platform structures.
Gauge infrastructure
Gauges of the Bavarian State Office for the Environment.
Typical Damage Patterns
What can be professionally captured at Lake Ammersee — a structured overview of the locally typical damage patterns:
Timber-pile damage
Support piles: fungal attack, bore holes, pile drift.
Algae growth
Seasonal growth layers.
Sediment deposits
Accumulation in bay zones and in the approach zones of landing stages.
On-Site Methodology
Lake Ammersee water is clear (visibility 2 to 4 m). ROV optics primarily, sonar for structured bed captures.
How Deep is Lake Ammersee?
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
81 m — ROV systems cover the entire depth range.
Lake area
Around 47 km² — Bavaria's third-largest lake after Lake Chiemsee and Lake Starnberg.
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 Ammersee
Beyond pure condition inspection, municipalities, hotel businesses and engineering offices at Lake Ammersee are increasingly asking for geometric data — for example for the rehabilitation planning of landing stages, the as-built documentation of high-quality hotel and private 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 Lake Ammersee, 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
Bavarian State Office for the Environment. Weilheim Water Management Office. Landsberg am Lech district administration, Starnberg district administration. Municipalities of Herrsching, Diessen, Riederau, Utting, Stegen.
Frequently Asked Questions
How deep is Lake Ammersee?
81 m maximum. For typical jetty and landing-stage inspection, working depths lie at 1 to 8 m.
Can we follow the inspection live?
Yes. On site, the client can view the live video on the operator's screen.
What is a typical arrival time?
From the Burgkirchen base, about 2 to 2.5 hours' driving time. Multi-day deployments are typical.
Does ScanSustain also offer survey and 3D mapping at Lake Ammersee?
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 Ammersee require official approval?
As a rule, yes. The responsible bodies are the Bavarian State Office for the Environment, the Weilheim Water Management Office as well as the Landsberg am Lech and Starnberg district administrations, and additionally the affected municipalities of Herrsching, Diessen, Riederau, Utting and Stegen. We clarify responsibility in advance together with the client.
How clear is the water at Lake Ammersee for the ROV inspection?
Lake Ammersee is clear, with visibilities of 2 to 4 m. For the inspection we primarily use ROV optics, complemented by sonar for structured bed captures.
