Abstract
Streamflow data collection is a critical part of water resources management in a subbasin, basin, and a country. River and streamflow monitoring provides data needed for water allocation for human and environmental needs and managing hydrologic extremes such as droughts and floods. Streamflow monitoring network implementation at a required density and successful continuous operation demands skilled personnel, sufficient fund, and organization. This necessity in Tanzania is evaluated with a case study of the Wami River subbasin streamflow monitoring program. Monitoring density, continuity, and data quality is evaluated. Existing rating curve representativeness is tested, and new rating curves are proposed. Water information and data gaps are shown as deficiency, and short- and long-term proposals are presented to improve monitoring network, data quality, data storage, and access.

Acknowledgments
The production of this chapter would have not been possible without the assistance rendered to me by the following individuals: Prof. Mtalo, F.W., Dr. Kongo, V., Dr. Valimba, Mr. Richard Charles, and Mr. Makoye, R. of the University of Dar es Salaam. Also, I am indebted to participants of both the Short Training Course on Data Quality Control and Quality Assurance for Nile DSS Tanzania Network Members held at the Blue Pearl Hotel, Dar es Salaam, Tanzania, in September 2010 and the Annual General Meeting of Ministry of Water held at the Corridor Spring Hotel in Arusha, July 25–27, 2012, for their crucial comments and advices which motivated the proposed way forward packages in this chapter. This initiative was partly sponsored by a regional collaborative research project entitled “Enhancing Climate Change Adaptation in Agriculture And Water Resources in the Greater Horn Of Africa” led by the Sokoine University Of Agriculture, Tanzania.
