Anna Jones' goal was the winning score.
Westmeath Ladies are just 60 minutes away from the All Ireland Intermediate Football Final after their one point win over Cavan.
Anna Jones' late goal sealed the victory on a scoreline of 3-7 to 1-12 and means that the Lake County will face Tyrone in the semi finals.
Jones also scored a first half penalty, with Sarah Dillon also chipping in with a goal moments after.
Manager Frank Browne praised his side's fitness and the impact off the bench:
