Defra has confirmed changes to the Ouse and Derwent Internal Drainage Board, with the reconstituted board taking legal effect on Friday 27 February 2026. The order sets the number of ratepayer‑elected seats at 11 and moves to a single, district‑wide election across the Vale of York.

Before this change, the board operated with 22 elected members split across three divisions - Ouse & Derwent (11), West Derwent (7) and Cliffe (4) - alongside councillors nominated by City of York and North Yorkshire. Those figures were carried on the board’s own site for the 2021–24 term. (yorkconsort.gov.uk)

The Environment Agency first set out the reconstitution in July 2024, proposing to consolidate the three electoral divisions into one across the whole district. Ministers have now confirmed that scheme. (gov.uk)

What changes, what doesn’t: the order resets how members are brought in. The first 11 will be appointed by the Secretary of State for a short, transitional spell before routine elections resume under the Land Drainage Act 1991. Day‑to‑day operations, assets and duties transfer unchanged to the reconstituted board, so pumping, weed‑cutting and consenting carry on.

Why it matters locally: the Ouse and Derwent district spans about 19,800 hectares between York and the rivers Ouse and Derwent, with seven pumping stations and around 264km of maintained watercourses. Villages including Riccall, Wheldrake, Hemingbrough, Dunnington, Elvington and Naburn sit inside the boundary. (yorkconsort.gov.uk)

The money stays close to home. In 2025/26 the board’s call was roughly £606,000: around 83% via special levies on City of York and North Yorkshire councils and about 17% through drainage rates charged directly to agricultural land. The rate was 5.40p in the pound. These figures offer a guide until the 2026/27 budget lands. (yorkconsort.gov.uk)

For farmers and land managers, the immediate ask is straightforward: watch for Defra’s first appointments, then the election timetable. With one electoral area, contests are expected to run district‑wide rather than by the old three‑way split. Council‑nominated representation continues under Schedule 1 of the 1991 Act, separate from the elected seats. (northlevelidb.org)

Contacts remain unchanged. Ratepayers can reach the clerk’s office at Derwent House, Crockey Hill (01904 720785). The Environment Agency notice lists the clerk and York‑based officials as points of contact for the reconstitution paperwork. (yorkconsort.gov.uk)

This is part of a wider tidy‑up of drainage governance. Elsewhere, boards such as Conington and Holme have also shifted to a single electoral district with fewer elected members, while Defra and ADA have been consulting on how costs are shared between farmers and councils - a technical change that underpins future rates.

What to watch next: the reconstituted Ouse and Derwent board is expected to set its 2026/27 programme and budget in the coming weeks. For rural wards across York and Selby, that’s the timetable to track - especially any shifts in pump upgrades, embankment repairs and drain maintenance priorities.

Drainage boards rarely make the front page, but they decide who sits round the table when pump hours, embankment works and rate bills are agreed. After a wet winter across the Vale, those decisions are as practical as it gets for farms, villages and small firms.
