The Shire of Broomehill-Tambellup says it has sustained less damage than initially feared from storms which unleashed 130 millilitres of rain in just two hours.
Wednesday's storms brought heavy falls to areas around Tambellup and had authorities fearing substantial infrastructure damage.
The shire says some roads have been damaged and will need to be repaired at significant cost but the situation is better than expected.
All but one road in the shire has reopened.
