Underwater Inspection at Lake Starnberger See — Bavaria's second-largest lake

Lake Starnberger See, at 56 km², is Bavaria's second-largest lake and is shaped by dense hotel, shipping and water-sports infrastructure. Landing stages of the Bavarian Lake Shipping line, numerous hotel jetties, municipal lido facilities and gauge structures generate a continuous need for inspection. ScanSustain inspects ROV-based down to the maximum depth of 127.8 m. 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 Starnberger See — subject to approval from local authorities and operators:

Ship landing stages

Landing stages of the Bavarian Lake Shipping line (Starnberg, Possenhofen, Tutzing, Bernried, Seeshaupt, Berg). Inspection of berth edges.

Hotel and private jetties

Hotel and private jetties around the lake. Findings capture of timber, steel and concrete components.

Lido facilities

Municipal lidos in Tutzing, Possenhofen, Starnberg, Bernried. Inspection of jetty and platform structures as well as anchor structures.

Gauge infrastructure

Gauges of the Bavarian State Office for the Environment.

Typical Damage Patterns

What can be professionally captured at Lake Starnberger See — a structured overview of the locally typical damage patterns:

Timber-pile damage

Support piles: fungal attack, insect infestation, pile drift.

Algae growth

Seasonal growth layers on jetty substructures.

Sediment deposits

Elevated sediment accumulation in bays and the approach zones of landing stages.

On-Site Methodology

Starnberger See water is clear (visibility 3 to 5 m). ROV optics primary, sonar complementary for structured measurement. Deployment planning outside the tourism peak season is preferred.

How Deep is Lake Starnberger 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

127.8 m — ROV systems cover the entire depth range.

Lake area

Around 56 km² — Bavaria's second-largest lake.

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 Starnberger See

Beyond pure condition inspection, municipalities, hospitality businesses and engineering offices at Lake Starnberger See 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 Starnberger See, the clear water quality (visibility 3 to 5 m, see On-Site Methodology) enables a good combination of optical detail capture and complementary sonar for the structured 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.

In preparation: Survey & Mapping is being expanded into a regular service. For pilot projects and preliminary enquiries at Lake Starnberger See we are already available now.

Frequently Asked Questions

How large is Lake Starnberger See?

56 km² area, 127.8 m maximum depth. Making it Bavaria's second-largest lake.

Are inspections possible during peak season?

Yes, with a longer lead time. Outside it (April, October) logistically simpler.

What is a typical arrival time?

From the Burgkirchen base about 2 hours' drive. Multi-day deployments typical.

Does ScanSustain also offer survey and 3D mapping at Lake Starnberger 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 Lake Starnberger See require official approval?

As a rule, yes. The responsible bodies are the Bavarian State Office for the Environment, the Weilheim Water Management Office, the Starnberg District Office and the affected municipalities. We clarify responsibility in advance together with the client.

Are the landing stages of the Bavarian Lake Shipping line also part of the inspection?

Yes, the ship landing stages of the Bavarian Lake Shipping line in Starnberg, Possenhofen, Tutzing, Bernried, Seeshaupt and Berg are among the characteristic structures that we examine for berth-edge findings.
