Up to High likelihood
Properties in CA5 7PH sit in the Environment Agency's High flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
| Likelihood band | Annual chance | Properties | Of which homes |
|---|---|---|---|
| High | greater than 3.3% | 5 | 4 |
| Medium | 1% – 3.3% | 1 | 0 |
| Low | 0.1% – 1% | 1 | 1 |
| Very low | below 0.1% | 0 | 0 |
Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
CA5 7PH gets about 842 mm of rain a year on average (wettest month October, 88 mm; driest April, 44 mm). That is 28% drier than the UK as a whole, which averages 1,163 mm a year.
A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.

The ground here sits at about 41 m above sea level and falls 20 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the west, 3.2 m higher.
The nearest watercourse on the river map is the River Caldew, about 110 m from the centre of CA5 7PH. It flows into the River Eden about 9.2 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Caldew nearest the centre of CA5 7PH. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
Because properties in the high likelihood band; 6 recorded flood outlines mapped nearby; 605 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around CA5 7PH. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
| Date | Mapped flood extent | Approx. distance |
|---|---|---|
| Feb 2020 | Storm Ciara 09_02_2020 | ~32.7 km |
| Feb 2020 | Dalston Storm Ciara 09-02-2020 | ~0.6 km |
| Dec 2015 | Dalston and Hempsgill 05_12_2015 | ~4.5 km |
| Jan 2005 | Dalston 08_01_2005 | ~0.3 km |
| Feb 2002 | Flooding 01_02_2002 | ~46.8 km |
| Oct 2000 | Flooding 28_10_2000 | ~14.4 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
