Flood Risk in Ulan, NSW: 2026 Assessment

Ulan, located in New South Wales, has a notable flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across New South Wales.

Historical flood data indicates that Ulan has experienced several moderate to major flood events in the past.

Ulan faces a moderate risk of flooding due to its proximity to the Goulburn River and surrounding waterways. Intense rainfall events can lead to riverine flooding, impacting low-lying areas and infrastructure.

For a comprehensive property-specific flood assessment including address-level elevation data, flood overlay mapping, and insurance cost estimates, use the ClimateNest full analysis tool. General suburb data cannot replace a site-specific evaluation.

Ulan sits within ClimateNest's suburb-level hazard model for flood risk. 13.3% of the suburb's land area is mapped in high-risk flood zones and 65.5% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Ulan.

Ulan (postcode 2850) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (17.9% of land in high-risk zones), riverine flood (13.3% of land in high-risk zones), surface flood (8.2% of land in high-risk zones). Exposure is not uniform across Ulan — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
