Abstract: The present investigation concerns with the aquatic macrophyte diversity and its role in understanding the reservoir ecosystem dynamics and species composition of aquatic macrophytes distribution in ten villages around Lower Manair Dam (LMD) were studied during 2013-2014. Forty eight different species of aquatic macrophytes were recorded in 04 classes, 20 orders and 26 families, which include five free floating macrophytes, ten submerged, and thirty three emergent species of weds were recorded. The percentage composition of class, order and families were calculated during this period. The free floating species Eichornia crassipes occurs throughout the year, while the submerged species Vallisneria spiralis, Ceratophyllum demursum, Hydrilla verticillata occur throughout the year. In the rooted floating category Ipomoea aquatica occurs throughout the year. The common name, habitat and IUCN (2013.2) status of the macrophytes has also been noted in the present paper. Key words: Macrophytes, Free floating, Submerged, Emergent, LMD.

Water covers about 70% of the earth’s surface and it exists naturally in the earth in all the three physical states of matter and it is always moving around because the water flows with the current. Out of the earth’s percentage of water covering the surface, only about 2.5% is fresh water and due to the fact that most are stored in deep groundwater, a small amount is readily available for human use. Water scarcity is becoming a major concern for people around the world and the need to protect the existing ones and find ways or means to provide safe water for individuals around the globe in adequate quantities with keeping the needs of future generations in mind. Water is life, and it is linked with lots of services either directly or indirectly, such as; human health and welfare and social and economic development of a community or country. The need to delve into Ghana’s water resources management is essential. The study reviewed existing literature on the various members of the Water Resource Commission (WRC) in Ghana; the various Basins in the country; the existing measures that the Water Resource Commission authorities have in place to deal with water resources management issues; the challenges that hinder the progress of their achievements and some suggestions that if considered can improve the current water resources management situations in Ghana.
