Current Affairs Angle: Lakes in the News

Exam current-affairs sections repeatedly draw on a small recurring set of lake-related environmental stories — worth knowing as short, self-contained narratives rather than isolated facts.

Dal Lake's shrinkage and restoration. Dal Lake's open-water area has been repeatedly documented as shrinking over recent decades — commonly cited estimates suggest it has lost a substantial share of its historical extent (figures vary by source and survey year, so treat any specific percentage as approximate) — driven by unauthorised construction and encroachment along its shores, untreated sewage and nutrient inflow triggering weed and algal overgrowth, and silt accumulation from the surrounding catchment. The Jammu & Kashmir government's Dal Lake Conservation and Management Project, running for over two decades with funding from the Japan International Cooperation Agency (JICA) among others, has focused on de-weeding, dredging, sewage treatment infrastructure, and relocating houseboat and shoreline populations — with mixed and still-incomplete results, making Dal Lake a recurring example in questions about the difficulty of urban wetland restoration specifically (as distinct from Chilika's more clearly successful restoration, below).

Chilika's mouth-opening restoration project. As covered above, the September 2000 artificial-mouth intervention at Satapada is the standard "successful lagoon restoration" case study, credited with restoring tidal flushing, reviving fish yields, and getting Chilika removed from Ramsar's Montreux Record in 2002 — routinely paired against Dal Lake's more troubled, still-ongoing restoration as a "compare and contrast" exam angle.

Loktak's phumdi management. As covered above, the interaction between the Ithai Barrage (which altered natural water-level fluctuation after its 1980s construction) and unchecked phumdi growth remains an active management challenge, periodically prompting phumdi-clearance drives that have drawn criticism from fishing communities whose homes sit on the same floating mats being cleared — a genuine and still-unresolved policy tension between ecological restoration and livelihood displacement, useful as an example in questions about conservation-versus-community-rights tradeoffs.

Memory hook: "Dal struggles, Chilika succeeded, Loktak is still fighting itself." Three Indian lake restoration stories, three different outcomes, easy to keep straight.

Practice Recall: Before reading on, name the one Indian lake restoration project in this book most commonly cited as a clear success story, and the one most commonly cited as still troubled/incomplete.

Answer: Chilika's mouth-opening project (success); Dal Lake's ongoing conservation project (still troubled).

One more recurring current-affairs angle: encroachment enforcement. Beyond Dal, Chilika, and Loktak, Kolleru Lake in Andhra Pradesh is a fourth commonly cited restoration story, distinguished from the other three by its specific cause and remedy: rather than sewage, weed growth, or floating-mat mismanagement, Kolleru's crisis was driven by illegal aquaculture — fish and prawn farms built directly on notified lake-bed land under encroachment permits that were later challenged in court. A 2006 Andhra Pradesh government demolition drive removed a large number of these unauthorised structures under directions linked to the Wildlife Protection Act (since Kolleru was also notified a wildlife sanctuary), making it a useful example in questions about the legal tools available to reclaim an encroached wetland — distinct from Dal Lake's slower, negotiation-and-relocation-based approach to a broadly similar underlying problem.

Memory hook: "Kolleru's prawn ponds got bulldozed by court order — a fourth restoration story, and the one driven by encroachment law rather than engineering or community negotiation."
