For the person whose pay moves with a verified saving. This chapter is ostensibly about rivers. It is actually about the only question that matters to you: how a shared gain is measured, where it is settled, and who is quietly charged for the paperwork.
A watershed payment and a gainshare are the same instrument wearing different clothes.
In both, one party changes what it does; a second party is better off as a result; and a share of the improvement flows back to the first party. In both, everything depends on three things and only three: an agreed baseline, a settlement point somebody already measures, and a disclosed cost of running the scheme. Every failure in this chapter's field is a failure in one of those three, and every one of them has an exact counterpart in a pay scheme.
So read the watershed arithmetic as a manual for your own ledger. The upstream landholder in this chapter is you. The utility is the firm. The intermediary is whoever administers your scheme. And the third term — the one almost nobody prints — is the one being taken out of your share before you see it.
Exercise 1.1 — Find your settlement point (one hour)
Read your scheme documents and answer one question: what exactly is measured, by whom, how often, and would it be measured anyway if the scheme did not exist?
Write it in this form:
| The measured quantity | |
| Who measures it | |
| How often | |
| Measured anyway, without the scheme? | yes / no |
| Where the number is published | |
| Who can dispute it, and how |
That last row before "yes/no" is the whole game. The reason New York City's watershed programme has survived since 1997 is that it settles against raw water quality at the intake — a measurement the city is legally compelled to take every day, at zero marginal cost to the scheme, with an existing chain of custody.
If your scheme's settlement point is measured only because the scheme exists, somebody is paying for that measurement, the cost is almost certainly coming out of the pool, and the number can be argued with in a way an intake reading cannot.
Exercise 1.2 — Find what is already working (one conversation)
Ask a colleague who has been through a full cycle: "when has this scheme paid out in a way that felt right — and what made that possible?"
Not what is wrong with it. You are collecting the conditions under which it works, because those conditions are what you will be asking to have more of.
Exercise 2.1 — Reconstruct your own pool, term by term
Your share is the last line of an arithmetic with at least five terms above it. Write out all of them, and mark each one agreed in writing or not:
verified improvement against baseline
− cost of verification
− cost of administering the scheme ← the third term
− any contingency or reserve held back
────────────────────────────────────────
= the distributable gain
× the share percentage
× your allocation within the share
────────────────────────────────────────
= what reaches you
Most schemes disclose the first line and the last. The three in the middle are where the money goes, and they are the exact terms the chapter says nobody prints.
Exercise 2.2 — Price the third term, the way the chapter does
A* = t / (b − c)
In a watershed scheme, t is the fixed cost per contract of screening, contracting, verifying and enforcing, and it is what determines whether the deal can happen at all. Worked, in a basin shaped like most basins: b is $115.71 per hectare a year and c is $80, so the net is $35.71 — against a transaction cost of $600 per hectare where the median holding is 2 hectares. Short by 17×. The scheme fails on paperwork, not on ecology.
Now run the same shape on your scheme. If the verification and administration lines together exceed a fifth of the verified improvement, you are in the same structural position as a two-hectare smallholder: the arithmetic is being eaten by the cost of doing the arithmetic.
And the fix is the same fix. Aggregate. One 3,000-hectare contract drops transaction cost from $600 a hectare to 40 cents and clears by 89×, replacing 1,500 contracts — and 1,124,250 pairwise relationships — with one. In a gainshare, aggregation means one scheme with one verification regime across a whole business unit, not a separate measured scheme per team. Per-team schemes feel fairer and cost more than they distribute.
Exercise 2.3 — Check whether your baseline was agreed before or after
The single most important document in a watershed transaction is the baseline, signed by both parties before anything is deployed. An unagreed baseline is not a baseline; it is a future dispute with a date on it.
Find yours. Note the date it was signed and the date the change was made. If the second is earlier than the first, that is the finding, and it is worth raising once, plainly, with three ways to fix it — re-baseline from an untouched comparator, adopt an external index, or agree a fixed reference period going forward.
Exercise 2.4 — Learn the two denominators
The New York programme returns 3.7 : 1 annualised over its ten-year commitment and 10.0 : 1 annualised over the programme's life. Both are honest. Neither is the number on its own.
Your scheme has the same ambiguity somewhere: a saving annualised over one year reads very differently from the same saving annualised over the asset life it created. Find out which convention your pool uses and get it written down. The convention is worth more to you than the percentage.
Four asks. They are ordered, and the first is worth more than the other three together.
Ask one: settle where somebody already measures. Propose that the scheme's metric be something the firm reports anyway — to a regulator, to a customer under contract, to an auditor. It costs the pool nothing, it cannot be quietly re-specified, and it is the reason the most durable scheme in this chapter's field has lasted since 1997.
Ask two: the administration margin as a disclosed line. Not a reduction in it — a disclosure of it. The chapter asks exactly this of the upstream intermediary, for exactly this reason: an invisible cost is an unmanaged cost. Once the line exists, it gets managed down without anyone having to argue about it.
Ask three: the baseline signed before deployment, by both sides. One page. Method, period, reference, signature, date.
Ask four: the protective sentence. The chapter's instrument contains a clause written on day one so that the year-four audit does not kill it:
this is a purchase of a deferred capital decision, settled at the intake against the regulatory threshold, and it was never a purchase of a per-parcel hydrological outcome.
Yours is the same shape. Write down, in one sentence, what your scheme is not claiming — which individual contributions it does not attempt to attribute, and why. A scheme that has said so in advance survives the audit that arrives asking who exactly caused the gain. A scheme that let the folklore stand does not, and the folklore is always more flattering than the instrument.
It has a statutory date. Published on a schedule, not when somebody champions it. The Rhine commission has coordinated five countries since 1950 with almost no enforcement power, and what it actually runs is a publication schedule.
Somebody senior's number moves with it. Not necessarily much. An unpaid metric is a hobby.
The administrator is older than the champion. Relationships, history and method live in an institution or they die in a reorganisation.
And the four ways it fails, so you can see them early.
The gauge is captured — the team being measured comes to own the measurement, and the record quietly improves. The first sign is a metric that stops having bad quarters.
The payment becomes an entitlement — after a few cycles the share is treated as income rather than as consideration for a practice, and it cannot be withdrawn even where the practice has stopped. The first sign is nobody being able to describe what the payment is for.
The alternative gets cheaper — the avoided cost the whole scheme is priced against erodes under you. Membrane filtration has been getting cheaper for thirty years. Re-run the arithmetic every five years and expect it to fall.
Attribution is demanded that was never designed in. Handled by ask four, and only by ask four.
And the delight. There is a particular pleasure in a ledger that closes — not the pleasure of a good number, the pleasure of a constrained one. When there is nowhere to put the difference, the difference has to be explained, and explaining it is how everybody in the room learns something. A scheme whose residual is always exactly zero is not a well-run scheme. It is a press release, and you are in it.
There is a discipline in this chapter that transfers directly to how you write up your own contribution, and it will make you both more credible and better paid.
Claim the practice, never the outcome. The upstream landholder in a well-designed watershed scheme is paid for the buffer standing and the plan followed — things that can be walked past and looked at. They are not paid for a milligram of turbidity that did not arrive at an intake sixty kilometres away, because nobody can show that, and a claim nobody can show is a claim somebody will eventually test. Write your own contribution the same way: I changed this, on this date, and here is what it looked like before and after. Let the aggregate outcome be aggregate.
Name your denominator in the same sentence as your number. A saving of a given size reads completely differently annualised over one year and over the life of what it created. The chapter's famous case returns 3.7 : 1 on one denominator and 10.0 : 1 on another, and both are true. The person who states theirs is trusted. The person who leaves it out gets a different denominator chosen for them later, by somebody with a different interest.
Say what you could not find out. One line, at the end, naming the thing you could not verify. It is counter-intuitive and it works: a write-up with that line is read as a measurement, and one without it is read as an argument. This is the same courtesy the chapter's instrument extends to its own audit, and for the same reason — the disclosure is what makes the rest of it load-bearing.
And leave alone the part that is not yours. Some of the gain came from a price move, a weather year, somebody else's project, or luck. Say so before anyone asks. It costs you almost nothing in the pool — allocation rarely turns on it — and it buys you the one thing that compounds across every cycle you will ever be in, which is that when you do claim something, it is believed.
Work down it once a year. Every "not yet" is a specific, askable thing.
| Yes | Not yet | |
|---|---|---|
| I can name the measured quantity and who measures it | ||
| It would be measured anyway, without the scheme | ||
| The baseline was signed by both sides before deployment | ||
| I can see the verification cost as a line | ||
| I can see the administration margin as a line | ||
| I know whether a reserve is held back, and how much | ||
| I know the annualisation convention and it is written down | ||
| I know my allocation method and can compute my own share | ||
| The scheme states in writing what it is not attributing | ||
| The metric has had a bad quarter at least once | ||
| Someone senior's compensation moves with the same number | ||
| There is a named second owner if the current one leaves |
For the meeting where you ask. Short, specific, and framed as improvement rather than suspicion — because it genuinely is.
"I want to make the scheme easier to defend, and I think there are three cheap ways to do it.
First, settle it against something we already report to the regulator. It costs the pool nothing, it has a chain of custody, and it stops the metric being re-specifiable.
Second, show the administration and verification costs as their own lines. Not to reduce them — to see them. Right now they are inside the pool and nobody is managing them, which is how these schemes usually die.
Third, write down in one sentence what the scheme is not claiming to attribute. Every scheme like this gets an audit in about year four asking exactly who caused the gain, and the ones that answered the question in advance survive it.
I can draft all three this week."
Then draft all three that week. The draft is the argument.
Discovery. When has this scheme paid out in a way that felt right, and what made that possible? · What do we already measure, for somebody else, that could carry this? · Who here has changed a practice that nobody has ever costed?
Dream. If every line of the pool were visible, what would we do differently next cycle? · If the administration cost were a published line, who would find a way to halve it? · What would we be able to claim honestly that we currently claim vaguely?
Design. What is the one aggregation that would let us run one verification regime instead of five? · What sentence should be in the scheme saying what it does not attribute? · Who signs the baseline, and when, and what does it fit on?
Destiny. What keeps this running when the person who built it is promoted? · Whose number upstairs moves with ours? · If the payment outlived the practice, who would notice first — and what would we want them to be able to do about it?
