Harbour engineer to the Fisheries Commission, from June 1825 until 1830 when the duties of the commission were transferred first to the Board of Inland Navigation and then, in 1831, to the new Office of Public Works.  The post of harbour engineer, to which Donnell was appointed, was a new one, created in order to relieve ALEXANDER NIMMO [1]  ALEXANDER NIMMO [1] of some of his many responsibilities.  Donnell inspected Nimmo's piers and harbour works in hand, cancelling some projects and modifying others.
