Flood Risk Analysis

Dover, located in Tasmania, 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 Tasmania.

Dover has experienced several minor flooding events in recent years due to heavy rainfall.

Dover faces a moderate risk of flooding, primarily from heavy rainfall and riverine overflow. The risk is expected to increase with climate change due to more intense rainfall events.

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.

Dover sits within ClimateNest's suburb-level hazard model for flood risk. 6.7% of the suburb's land area is mapped in high-risk flood zones and 83.5% 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 Dover.

Dover (postcode 7117) 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 surface flood (13.8% of land in high-risk zones), extreme wind (9% of land in high-risk zones), riverine flood (6.7% of land in high-risk zones). Exposure is not uniform across Dover โ€” individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions

Is Dover at risk of flooding?

Based on available data, Dover has a notable flood risk profile. Flood risk varies by address โ€” check your specific property for precise flood zone mapping and elevation data with ClimateNest.

What flood insurance costs can I expect in Dover?

Insurance costs for flood cover in Dover depend on the property's flood zone classification, elevation, and proximity to waterways. ClimateNest provides address-level insurance cost estimates based on your property's specific hazard exposure.

Does flood risk affect property values in Dover?

Yes, flood risk can affect property values in Dover. Properties in mapped flood zones may experience lower buyer demand, reduced valuations, and higher insurance costs. Lenders increasingly assess flood exposure as part of mortgage risk evaluation.

How does elevation affect flood risk in Dover?

Elevation is a critical factor in flood risk. Properties at higher elevations within Dover typically have lower flood exposure than those near waterways or in low-lying areas. Address-level elevation data combined with BOM flood mapping provides the most accurate picture.

What share of Dover is exposed to high surface flood risk?

ClimateNest's hazard overlay maps 13.8% of Dover in high-risk zones for surface flood, with a further 65.4% in moderate-risk zones. Suburb-level exposure is not uniform โ€” individual properties can differ from these averages, so an address-level check is recommended.
