From 9df3cf979133ede64ccedc3a10cc52325455081d Mon Sep 17 00:00:00 2001 From: Mikkeli Date: Thu, 10 Sep 2026 01:47:32 +0900 Subject: [PATCH] =?UTF-8?q?274-dev:=20drop=20=E5=90=8D=E7=A7=B0=E4=B8=8D?= =?UTF-8?q?=E6=98=8E=20and=20=E3=83=99=E3=83=AA=E3=83=99=E3=83=84=E5=B7=9D?= =?UTF-8?q?=20from=20the=20watercourse=20shortlist?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Author's calls: 名称不明 has no name to use, and ベリベツ川 is mostly farm waterway now and sits west of 川端橋, outside the range. デチン沢川 kept pending verification — 沙流川水系, 河川コード 8101070000 (the 「その他」 group), 42.87965 / 142.43823. Notes that the list is a shortlist to pick from, not a set of things each of which earns a line.
