It concludes next Wednesday, July 25th, with the deed rewarding 100 Tokens of the Lake and Rivers. The 16 weekly quests give 5 tokens each, so if you're behind, you may have more untapped tokens.
Your progress is tracked with a deed The Lay of Rust and Rime in the Epic section of your deed log. You can check https://lotro-wiki.com/index.php/The_Lay_of_Rust_and_Rime to see where to get the next quest.
