The Kolpa is a freestone river in the Jugovzhodna Slovenija region of Slovenia. The clubs' online permit shop, ribiskekarte.si, lists it. This page covers the Kolpa on the Croatian border, from Osilnica to Metlika. Also called Kupa.
Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish. Most waters here need a rod licence or permit and often a beat booking or club ticket; the listing pages under Regulations say which.

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.
At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.
Like the Kolpa? Same fish, US waters.

Not a statement of access, fish presence or conditions.
A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.
Live readings come from the named provider when the page is shown, under the licence shown on each card. Designations, species and the flagship note link to the agency or body that publishes them; this page copies only the list wording and the species names. Guide and shop listings come from the Legendary directories. Position: the gauge Kolpa - Metlika. Water type is our own classification.
Agencija RS za okolje (ARSO) publishes no record for the date to compare it with, so there is no verdict.
