加拿大斯奈尔小瀑布水电工程是当地民众私人合伙完成的工程范例，其所在地区冬季漫长，气温低，气候条件对施工情况有所限制。为此修建了横跨斯奈尔河的11孔迷宫溢洪道。在施工过程中，进行了合理的安排，使工程在合同期限内如期完成并投入运行。 The Snell Cascade Hydroelectric Project in Canada is an example of a project completed by a local private partner who is long in winter and has low temperatures and climatic conditions that impose restrictions on construction. For this purpose, an 11-hole maze spillway across the Snyder River was constructed. During the construction process, reasonable arrangements were made for the project to be completed and put into operation as scheduled within the contract period.
