Area 5 extends from the eastern end of the Old River Road to Brockmere Cliffs Road, including the Amateur Islands.
One of the first settlers to the Brown's Bay (also known as Patterson Bay) area was Daniel Patterson. He was granted Lot 10 of Front of Yonge Township in 1798. James Brown bought property along the waterfront from the Patterson family in 1833, hence the name Brown's Bay. Until 1969, a shipwreck rested on the river bed in Brown's Bay The ship, known as the Brown's Bay Wreck, was probably the H.M.S. Radcliff, a gunboat built in the Kingston shipyard in 1817. If the ship is indeed the H.M.S. Radcliff , it was the last boat listed on the Kingston navy yard inventory before the signing of the Rush-Bagot Treaty. This treaty limited the number of armed ships that Britain and the United States could keep in service on inland waters. The boat was kept in good condition, despite not being used in combat. The hull was replanked and tarred with pine pitch to prevent rot. The first layer of planks was fastened with copper nails. By the early 1820's, boat builders knew that regular iron nails would last the life of a boat used in fresh water, so the copper nails were replaced. Eventually steam engines replaced sail powered gunboats. The naval yard received orders to sell what boats it could and to destroy the rest. The Brown's Bay Wreck likely did serve as a farmer's work boat. The wreck was raised in 1969 and moved to a permanent display site at Mallorytown Lading.
East of Brown's Bay, Jones Creek was at one time called the Toniata River by the natives. A map dated 1846 shows two grist mills and a saw mill on the banks of the creek.. One of the mills was owned by the Jones family, the others by the Mallorys. Prior to the permanent bridge being built, residents west of Jones Creek had no direct road access to Brockville. In 1892, a contract was granted to George Turkington and Henry Clow to build a scow that would serve as a ferry for travelers. This service was discontinued in 1903 when the scow was declared unsafe. The following year a bridge was built. The original bridge was too low to allow boat traffic access to Yonge Mills. It was blown up and burned by a group of angry locals. In 1904, Sir Clifford Soften contributed towards the construction of a new bridge.
