The Navrongo-Tono dam is one of the largest agricultural dams in West Africa and serves as a place for year round farming.

About 2,490 hectares of land is irrigated with water from the 2 mile long dam which serves seven villages in the Kassena Nankana District. The dam was built in the late 70's and early 80's by Taysec, a British engineering company.

The popular cash crops being cultivated on the project are rice, soya bean, and tomato. Future cash crops may also include cashew. While ICOUR tomatoes are marketed in the southern region of Ghana, the soya bean is sold to industries throughout Ghana.

The dam allows for farming around the year and has greatly aided in the development of Navrongo. Unfortunately the dam has also created a problem by creating the ideal conditions for a certain type of snail which participates in the life cycle of the schistosomiasis parasite. This parasite invades the body through the skin and resides in the intestinal tract or walls of the bladder. It can cause painful bleeding and, if left untreated, sterility.

Despite the parasite dangers, the dam and lake offers opportunities for water sports and relaxation at the guesthouse.
