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.

very lowWell below normal for the date. Fish crowd into whatever deep, cool water is left, which makes them findable and also makes them fragile — a fish played hard in warm shallow water often does not recover. It is dropping, roughly 24% over the week ahead.

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
The sweet spot for a vegetable garden. Nearly every nutrient is at its most available somewhere in this band, which is why it is the number every soil guide tells you to aim at.
Happy here without a fight
Almost everything: tomatoes, beans, squash, lettuce, apples, most perennials and most lawn grasses.
If you want the rest
Nothing needed. Compost keeps it here; heavy lime would push it past useful.
Working it
Fine and fertile, holding water better than sand without clay's stickiness. It caps over in heavy rain, so it wants a mulch or a cover crop rather than being left bare.
