A partially dissolvable plug is to be deployed in a position in a wellbore formed in a subsurface formation. The partially dissolvable plug comprises a first portion comprising a dissolvable material that is to dissolve over time after exposure to a downhole ambient environment in the wellbore and a second portion comprising a non-dissolvable material that is to create a flow restriction as the flow of fluid passes through the partially dissolvable plug. The first portion is to prevent a flow of fluid from downhole to a surface of the wellbore until at least a portion of the dissolvable material is dissolved. A flow rate is to be determined based on a detected change in a downhole attribute that is to change in response to the flow of fluid passing through the partially dissolvable plug after at least a portion of the partially dissolvable plug is dissolved.
