Issued without a dust jacket. -- This monograph represents a definitive summary of a half-century of practical experience in lake restoration. Björk, a Professor Emeritus of Limnology at Lund University, moved beyond theoretical ecology to develop "active" restoration techniques that address the root causes of aquatic degradation. Core Philosophy and "The Fine Art": The title's reference to "The Fine Art" reflects Björk's belief that every lake is a unique individual requiring a bespoke "diagnosis" and "prescription." He argues against standardized, "one-size-fits-all" solutions, instead advocating for a deep understanding of the specific physical, chemical, and biological interactions within a given water body. Key Methodologies and Techniques: The book details several pioneering methods developed or refined by Björk and his team, including: - Sediment Removal (Suction Dredging) [techniques for removing nutrient-rich "internal loading" layers to stop the cycle of self-fertilization in eutrophic lakes]; - Sediment Oxidation (The Riplox Method) [injecting calcium nitrate and iron chloride into sediments to chemically bind phosphorus and stimulate decomposition]; - Biomanipulation [reshaping the fish and plankton communities to restore clarity and ecological balance]; - Aeration Systems [designing specialized equipment to oxygenate bottom waters without destroying the thermal stratification of the lake]. Notable Case Studies: A significant portion of the text is dedicated to long-term results from world-famous restoration projects, such as: - Lake Trummen (Sweden) [a landmark project where Björk proved that removing polluted sediment could successfully revert a "dead" lake to a healthy state]; - Lake Hornborga (Sweden) [a massive restoration of a drained wetland area to support bird life]; - Projects in Brazil and Jamaica [demonstrating how these limnological principles apply to tropical and subtropical environments].
