Historic Bremer River Flood Inundation Lines

January 1974 and January 2011 flood extents for the Bremer River, captured by the Ipswich City Council. The data represents maximum inundation lines based on surveyed levels from debris lines after each event. The 1974 extents do not include the area of the former Moreton Shire Council.

Use Cases

• Flood risk modeling based on historical maximum inundation lines.
• Urban planning and zoning for flood-prone areas using surveyed extents.
• Emergency response planning for the Bremer River catchment.
• Historical disaster impact analysis comparing 1974 and 2011 events.

Strengths

• Covers two major historical flood events (1974 and 2011).
• Data is based on post-event surveyed levels from debris lines.
• Published under a permissive CC-BY-4.0 license.
• Available in multiple geospatial formats (KML, SHP, WFS, GEOJSON, WMS).

Limitations

• Column names and data structure are unknown from the provided sources.
• The 1974 dataset has a noted spatial exclusion (former Moreton Shire Council).
• Metadata is sparse, lacking information on row counts, file sizes, and specific geometry attributes.
