The river traditionally supported many local industries, from the salmon fishing industry to shipbuilding. At one stage, Garmouth functioned as the shipbuilding capital of Britain, with timber from the forests around
Aviemore and
Aberlour being rafted down to create wooden-hulled ships. The river is known by anglers for the quality of its salmon and
trout fishing, including a particular form of fly fishing where the angler uses a double-handed fly rod to throw a '
Spey cast' whereby the fly and the line do not travel behind the fisher (thereby keeping these away from the bushes and trees lining the banks behind him or her). This type of cast was developed on the Spey. Speyside
distilleries produce more
whisky than any other region.
Scotland's Malt Whisky Trail is a tourism initiative featuring seven working Speyside distilleries, a historic distillery and the
Speyside Cooperage. The concept was created in the early 1980s. The region is a natural for whisky distillers because of three benefits: it is close to barley farms, contains the River Spey and is close to the port of Garmouth. The
Speyside Way, a
long-distance footpath, follows the river from Newtonmore to the sea, passing through the
County of Inverness,
County of Banff and
County of Moray. The River Spey is unusual in that its speed increases as it flows closer to the sea, due to a broadly convex long-profile. For most of its course the Spey does not meander, although it rapidly moves its banks. South of
Fochabers a high earth barrier reinforces the banks, but the river has broken through on several occasions, removing a large portion of
Garmouth Golf Course, sections of wall surrounding
Gordon Castle, parts of the Speyside Way and some of the B9104 road. The
Spey Viaduct (pedestrianised ) between Spey Bay and Garmouth was originally designed with its main span over the main flow of the river, however before construction was completed the river had changed its course and was running at one end of the bridge. The viaduct collapsed on 14 December 2025. ==Settlements==
