It arrives here
Gulf of Mexico
This water joins the largest drainage in North America and travels south for thousands of kilometres to the Gulf. What runs off the fields upstream of you arrives there too, which is why a dead zone the size of a small country forms off Louisiana each summer.

normalAbout what it should be for the date. The river is doing its ordinary work — sorting gravel, feeding its banks and moving fish around at the pace everything in it is adapted to. It is dropping, roughly 10% over the week ahead.

About 4.0 billion years old — older than free oxygen in the air, and older than almost any fossil.

Bedrock and soil figures are modelled from national geological surveys and global soil mapping, at a resolution of a few hundred metres — right for the shape of a district, not for a particular garden. River discharge is modelled, not gauged. For anything that matters, dig a hole and look.

The soil it made
What that means
Comfortable for woodland plants and a little tight for the vegetable garden. Brassicas sulk, and clubroot is worse at this end of the scale.
Happy here without a fight
Blueberries, raspberries, potatoes, rhubarb, carrots, most conifers, azaleas and hydrangeas — which come out blue here.
If you want the rest
A dressing of lime in autumn brings the vegetable beds up without touching the fruit. Leave the blueberries well alone.
Working it
A balance of sand, silt and clay — the texture that holds enough water to matter and still drains, which is why loam is the one everybody wants.
