The papers in this volume are the peer reviewed proceedings of the Kinneret Symposium on Limnology and Lake Management 2000+, held in September 1998 at Kibbutz Ginnosar, Israel, on the shores of Lake Kinneret (Sea of Galilee).
The papers deal with all aspects of lake management, corresponding to major sessions of the Symposium:
1) Lakes and Reservoirs as water supply sources;
2) Operational Limnology; new approaches;
3) Management driven research: case studies;
4) Nutrient cycling;
5) Control factors of aquatic population dynamics
Lake Kinneret is Israel's only large freshwater lake and serves as the main reservoir for the National Water Carrier that provides almost a third of the country's water requirements and an even higher proportion of drinking water needs. Since 1968, the Yigal Allon Kinneret Limnological Laboratory has carried out basic and applied research aimed at understanding how present and future environmental conditions may affect water quality and how best to protect the lake ecosystem in an era of rapid regional development. Largely as a result of the monitoring and research efforts of Laboratory scientists, the management authorities (Israel Water Commission, the Kinneret Authority and Mekorot Water Company) have been able to maintain acceptable lake water quality over the years.
For over 30 years the Laboratory has fulfilled its mandate as "caretaker of Lake Kinneret'' and in doing so has acquired an outstanding international reputation for innovative and significant research. As a result the laboratory has been involved in joint studies, exchange programs and training courses with many other countries, (including Australia, Belarus, Canada, Chili, China, Egypt, France, Germany, Hungary, Italy, Japan, Kenya, San Salvador, Sweden, Thailand, Turkmenistan, Ukraine, United Kingdom and the U.S.A). Laboratory scientists continue to search for environmentally acceptable solutions to the future water requirements of Israel and her neighbours as part of the evolving Middle East Peace Process.

"This volume of Advances in Limnology contains 40 papers, which were presented at the Kinneret Symposium on Limnology and Lake Management in 1998. For the better orientation, the papers are grouped into five sections, which concern on lakes and reservoirs as water supply sources, on the operational limnology and lake management, on the nutrient cycling and finally on the factors controlling aquatic population dynamics. Therefore it can be experienced even at the first looking-on, that this band is an exhaustive one. Everybody, who is interested in limnology, especially in algology, can read in this book about new methods and new approaches in these fields. Without highlighting any of these articles, we would like to remark that these progressive publications are of international interest, although certainly, much of them deal with the Lake Kinneret. One can find here description on investigation, which solve practical problems of water utilising, too. Nowadays the management of lakes and water-bodies of other kind are widely and often negotiated points of view. Information and case studies about this topic are also available in this book. 264 figures – among them also coloured ones – and 64 tables make the certain reports more interesting to study and easier to understand. I recommend this very useful book for all limnologists, phycologists, and algologists working on aquatic environment all over the world."

"[...] In summary, this compendium contains a wealth of peer-reviewed information most contributory to contemporary limnology. Although many papers address specific problems and phenomena of Lake Kinneret, most of the processes analyzed and conclusions are more widely applicable. Even though these papers of this journal series are not abstracted as widely in information services as is the case of contents of many conventional scientific journals, they are important contributions that should be recognized. The work is highly recommended for ecological research libraries."
