定山溪水庫資料館 / Jozankei Dam Museum

定山溪水庫資料館（位於札幌市南區）是位於定山溪水庫下游園區內的設施，可免費入場參觀。在那裡可以以水庫的模型學到水庫的構造以及如何建造成的。也可以學習到水庫周遭的生物或是自然環境。也設有用手轉動把手就可以發電的裝置。在室外也展示著使用渦輪等設備來水力發電的大型裝置。

Jozankei Dam Museum (Sapporo City Minami-ku) is free to enter, and it is located in Jozankei Dam Downstream Park. Visitors can learn about Jozankei Dam's structures, how they were constructed, and how the dam facilities work. Learning is through observation of miniature models. Visitors can also learn about the ecological system around the dam - such as what creatures inhabit the area and what natural environment can be seen. There are interesting learning tools too, such as one which allows people to experience turning a handle to generate electricity. Outside the museum, some real big devices used in hydraulic power plants are exhibited.
