Bird identification

Whilst walking round a reservoir recently I saw a bird that I am certain was a Dotterell.  Initially, I assumed it was a thrust but it was quite a different shape and did not have the long tail of a thrush.  I went home and looked at the RSPB site and identified it immediately.  It was near a lot of lapwing so obviously likes the same conditions, but I believe I will be told it can't possibly have been a Dotterell - wrong time of year, rather rare etc.  The conditions were very snowy and cold.  I live in Kent.  Any views anyone.
