What species of lymnaeidae is this?

[lucas]

I found some of these snails in the lake near me (British Columbia). At first I thought they where baby lymnaea stagnalis. Eventually they stoped growing at only about 0.4" though. Then yesterday I found a baby snail that couldn't be from any other species (there is a radix peregra but it was in a different container until Thursday so there's no way it laid eggs that then hatched in 2 days) at first I thought the baby was a bladder snails but I realized it was right coiling. I knew then that those snails where not great pond snails. They lived alongside Physella sp and helisoma anceps. They where the second most common species (they was lots of Physella but I only ever found a few helisoma anceps. There wasn't a lot of these snails but they where uncommon). I did some research and I think they are a species of Galba or Stagnicola. I can't figure out which species though. For reference here is a list of the species of those genera that occur in British Columbia. All of them occur in lakes too. Oddly, the global conservation status of all of those species is the equivalent of Least concern but only one was LC in British Columbia.
