The Ilvar Delta dispute
Valdoria and the Kesh Federation both claim parts of the river mouth where the Ilvar meets the Merovan Sea. The argument is about shipping, fishing and a boundary that the river itself keeps moving.

Where the delta is
The Ilvar river forms much of the line between Valdoria to the west and the Kesh Federation to the east. Where it reaches the Merovan Sea it splits into two shipping channels and a scatter of low sandbar islands. Both countries claim parts of it.

What the two sides want
Kesh points to the 1987 navigation accord, which it says guarantees its pilotage rights on the eastern channel. Valdoria wants joint monitoring of the channels and the return of fishing communities displaced since 2020. Neither side has given up its claim to the outer islands.

Why the map is part of the problem
Sediment surveys show the eastern channel has moved about 300 metres east since 1987. A boundary drawn on a map from that year no longer matches the water, so any agreement has to decide whether a line follows the river or stays put.

Where things stand
In 2026 the two governments met in Port Alder for their first direct talks in six years, hosted by the Merovan Islands. A draft framework would create a joint commission to monitor both channels but leaves sovereignty over the outer islands open.
Timeline
1987
Navigation accord
Valdoria and Kesh agree rules for shipping through the delta; Kesh later cites it for its pilotage rights.
1987 onwards
The channel moves
The eastern channel drifts steadily east, reaching about 300 metres from its 1987 line.
2020
Channels closed
The eastern channel closes to scheduled traffic and fishing families leave towns such as Sennick. Direct talks stop.
2026
Port Alder talks
The two governments return to direct talks, with a draft framework for a joint channel commission on the table.
Glossary
- An agreement on shipping through the delta. Kesh reads it as guaranteeing its pilotage rights on the eastern channel.
- The right to supply the licensed pilots who guide ships through a difficult channel, and to collect the fees.
- Low sandbar islands at the seaward edge of the delta, claimed by both governments.
- Negotiations in which mediators carry messages between delegations in separate rooms.
- A body proposed in the draft framework to monitor both shipping channels.

Who is who
institution
Parliamentary republic on the delta's west bank; its delegation is led by Foreign Minister Ilse Marenko.
institution
Federal state on the east bank; its delegation is led by Deputy Chancellor Ruben Askari.
institution
Neutral island state that hosts and mediates the talks in Port Alder.
group
Thousands of people displaced from towns such as Sennick since the 2020 channel closures.
place
The contested river mouth, with an eastern and a western shipping channel.
Common questions
Is this a dispute about land or water?
Both. The core arguments are about who controls the shipping channels and who owns the outer islands. Because the channels move, the two questions are tied together.
Why do the fishing towns matter?
Thousands of people were displaced when the channels closed in 2020. Their return is one of Valdoria's stated aims, and local councils want a say in any new arrangement.
What would a joint commission do?
Under the draft, it would monitor traffic in both channels. It would not decide who owns the outer islands, which is why some commentators doubt it would last.
