Tyler McGladdery (76) notched a half-century whilst there were also contributions from Connor Marshall (47), Daryn Smit (42) and Sam Conners (40 not out) to take the hosts to an all out total of 404.
Tony Palladino then took the late wicket of Ross Greenwell (3) to reduce Durham to 14-1 at the close on Day One.
Derbyshire were watchful in the opening hour to take the score to 57-2, before Dal joined McGladdery at the crease to put on a 74-run stand for the third wicket.
McGladdery fell for 76 to end the partnership before three Derbyshire wickets fell in quick succession as the hosts slipped to 160-6.
However, Dal continued his fine form alongside Smit and Marshall to record half-century partnerships with both batsmen before the all-rounder fell for 126, with the score 350-9.
