New enough, long enough, within policy. Hook short enough and sourced, although I don't read Swedish and I don't have access to the source anyway. QPQ not needed. L293D (☎ • ✎) 10:28, 11 June 2019 (UTC)[reply]

Thanks L293D, the external links to the sources are in the Sommen charr page. Which hook do you think is the best one? Sommakoa (talk) 03:45, 12 June 2019 (UTC)[reply]

ALT1 or 2, I'll leave it to the promoter. L293D (☎ • ✎) 16:09, 13 June 2019 (UTC)[reply]

Hi, I came by to promote this. Is there a cite verifying the "up to 60 m" line in the article? Yoninah (talk) 20:36, 7 July 2019 (UTC)[reply]

*Yoninah, the 60 m is a a depth approximation commonly used, because lower numbers (eg. 53 m) are those of verified depths, but these verified does no preclude slighly deeper parts are likely to be found if more detailed studies are done. Bathymetric studies of the lake are mostly interested to get precistion in shallows to to aid navigation.

Det största uppmätta djupet är är 53 m, men inofficiella mätningar har visat över 60 meters djup. Medeldjupet i sjön är 17 m.

Translation:

The greatest measured depths is 53 m, but unofficial measurements have shown depths of more than 60 m. The average depth is 17 m.

Source: Fishing authority. I see no problem to change 60 m to 53 m in the DYK text -Sommakoa (talk) 10:24, 11 July 2019 (UTC)[reply]

Replacing tick as matter has been resolved. Cwmhiraeth (talk) 06:20, 13 July 2019 (UTC)[reply]
