By 1500 the loch drainage had begun with the Gruipe Gutter cut to drain the loch waters into the River Irvine, the natural outflow being a burn that ran into the Annick Water at Lockwards.
Patrick Warner of Ardeer, the parish minister of Irvine, had been exiled to Holland following the Battle of Bothwell Brig and had learned the techniques of drainage from the Dutch.
He first dug ditches or 'gotts' that ran into the drain known as the 'Minister's Cast' that ran from the northern end through the old Williamfield area and then into the Irvine as Jenny's Burn.
This worked well and the existing drain or stank (a stretch of slow-moving water), known as the 'Grip or Gruipe Gutter' running through the town along what is now Chapel Lane, dried up.
Others drained the south end of the loch via the outflow that ran into the Annick Water.
The newly drained areas became valuable farm lands.

In August 1682 the Baillie of Irvine, Hugh Montgomery, was reimbursed for a payment of two shillings made to Robert Miller for "casting the goat leading to the loch running betwixt the taelling rigs and the town lands."

The Tanzie Well, St Anne's or the Washing House Well is a spring that runs into the River Irvine near the Pouther House on the Golf Fields.
This spring or spout still exists beside the New Bridge, the pedestrian bridge, and is said to drain water from the old Scott's Loch site.
