The Water Code
You turn a tap and never count the cost, certain water is endless and someone else's to manage.
You read the slope of your own land, catch the storm before it leaves, and ration the dry months from a record.
A Whole-System Field Journal for Homestead & Garden Water
A working hydrology log for irrigation systems, rain harvest, and year-round programming of garden water. Not a primer. A working record — built to be kept on the bench, opened to the next blank entry, and filled in with a pencil.

ledger.

Field-tested
layouts.
Structured layouts with room to write — the reference charts and guided logs you'll actually use, page after page.

Questions, answered
How is it delivered — and how fast?
The digital edition is an instant download — the print-ready PDF arrives by email the moment checkout completes, readable on any device or printable at home. Paperback and hardcover are produced on demand and ship from the US, typically 5–8 business days.
What's the difference between the formats?
Same interior, 3 ways to use it. Digital ($9.99) is the instant PDF — print the pages you need, as often as you need. Paperback is the everyday bench copy. Hardcover is the durable, giftable edition. Buy digital to start today; add print anytime.
What's actually inside?
A working irrigation · hydrology journal — structured fields, not blank pages: 12 zone blueprints · 5 mm grid · specs & flow calc; Per-species hydration sheets · 7 plants; Essential formulas · volume · gravity head · harvest; Symbol legend · 10 hydraulic symbols. 6 × 9 inches, undated.
Is it for beginners?
Yes — the reference pages teach as you log, so a first-timer can follow the targets and a seasoned keeper moves faster. You learn by doing, not by reading a textbook.
Is it dated? When can I start?
It's undated by design — start any time, any season, and never waste a page. You write the dates as you go.
Can I give it as a gift?
It's made to give — ships in clean, unbranded packaging, and the hardcover makes a keepsake for the keeper who has every tool but no system.
Paper, size, and will pencil show through?
6 × 9 inches, matte cover, white paper chosen so pencil and ink don't ghost to the next page. Lies reasonably flat on the bench.
