“…It lies at latitude 4° 41' north and longitude 102° 40' east and receiving water inputs from main rivers, the Terengganu River Basin [11]. The main reason of this lake was constructed for the purpose of generating hydroelectric power which is able to supply electricity to all state in Peninsular Malaysia.…”

“…IRBM aims to establish a framework for coordination whereby all administrations and stakeholders involved in river basin planning and management can come together to develop an agreed set of policies and strategies such that a balanced and acceptable approach to land, water and natural resource management can be achieved. IRBM program was run by Department of Irrigation and Drainage (DID) which collaborated with the Danish International Development Agency (DANIDA) representing the Denmark government used in the development of the Selangor River Basin and Kedah River including the aspects of legislative institutions, the provision of legislation on water resources, human resource, river basin management and planning and improving environmental management practices [21][22][23][24][63][64][65].…”

a b s t r a c tRivers, which provide 90% of the readily available freshwater, are key components of global water resource system. Terengganu River experienced deterioration in water quality, resulting from the sedimentation, anthropogenic, geomorphology problems and unsustainable development management around the river basin. This study was implemented to prove the sedimentation problem especially the formation of total suspended solid (TSS) and annual sediment load (SL). The technique of analysis of primary data obtained which determine according with the procedure TSS and SL. The results showed that the highest average of TSS (mg/L) is 67.2 (wet season) and 128.2 (dry season) which are class III. While the highest turbidity is 43.57 (wet season) and 21.57 (dry season) which are Class II based on National Water Quality Standard (NWQS). The highest annual average estimation for annual SL flow out from the Terengganu River Basin is 6,846.709 tonnes/km 2 /year (Manir River Basin) the lowest in the Pauh River Basin is 2.850 tonnes/km 2 /year. The statistical analysis proved the weak regression relationship between TSS, river discharges (Q), SL and area of catchment caused by the anthropogenic factors and uncertain climate changes. Furthermore, the water in the Terengganu River was classified under class III caused by the active land use activities especially industrial and development but it is still suitable for recreational activities and safe for body contact because its water quality index is not less than 65% which early stage of Class II. The contributors of sedimentation problems are from unsustainable land use such as sand mining activities which effectively trap the bed sediments, backflow that carries out high sediments, as well as sedimentation produced due to the river bank erosion. This study suggests the sedimentation management methods including land use settlement, cliff erosion problems, settlement and negotiable of uncontrolled development operations in Terengganu River and the integration of river management methods based on integrated river basin management in Terengganu River Basin is recommended.

“…It was recognized as a problem for more than 60% of the 90 major Malaysian lakes studied in 2005 (Sharip & Yusop 2008;NAHRIM 2009). A follow-up study from the 2004 desk study was conducted in 2012 on 15 selected lakes and reservoirs during the dry season, with the finding that almost all the lakes contained high nutrient levels and were categorized as being eutrophic (Sharip et al 2014). Lakes with serious eutrophication problems include Sembrong Reservoir, Chini Lake and a number of urban lakes.…”

The deterioration of water quality in lakes resulting from unsustainable catchment practices requires concerted efforts to address them, in the form of cooperation among government agencies and institutions, private bodies and the community‐at‐large. Research that provides an understanding of a lake's ecosystem is an important aspect of making informed decisions for sustainable management and governance of lakes. The present study describes the findings of literature reviews on Malaysian lakes, and the national efforts made to establish an agenda for lake research and development in Malaysia directed towards integrated lake basin management (ILBM). The main findings and outcomes of the National Lake Research Blueprint workshop in April 2014 on the issues facing lakes and reservoirs are highlighted. Seven research themes were identified, namely (i) ecosystem services and socio‐economic development, (ii) governance, (iii) water quality and pollution, (iv) eco‐hydrology and basin management, (v) biodiversity and natural products, (vi) physical limnology and hydrodynamics and (vii) technology. The goal is to enhance research and development on sustainable lake basin management directed to conservation and development targets. The findings of this study provide an integrated research framework that can support ILBM governance elements (pillars) elsewhere, and to call for researchers to participate in much‐needed research areas.
