Section 90 declares the Polavaram Irrigation Project a national project. It says Union control of its regulation and development for irrigation is expedient in the public interest, deems Telangana's consent to have been given, and directs the Central Government to execute the project and obtain requisite clearances including environmental, forest, rehabilitation and resettlement norms. These four elements should be learned together. “National project” is a legal classification; it is not proof that the dam or distribution network was physically finished in 2014.

Polavaram lies on the Godavari system. Its construction affects irrigation, hydropower and flood management discussions, but Section 90's wording should not be casually rewritten as a promise to pay every conceivable associated expense. Subsequent funding decisions, cost revisions and implementation arrangements require their own official orders. Environmental clearance and rehabilitation are not optional extras just because Parliament named the project. For an exam, choose the Section 90 fact asked and avoid adding a claim the text does not make.

Worked example: Section 90 declares Polavaram a national project and sets Union responsibilities. It does not say that every canal, rehabilitation site and downstream benefit was completed on the appointed day. If a multiple-choice option equates national-project status with physical completion, reject it. Read each subsection for legal obligations, then use dated project reports for financial and construction progress.

Active recall: Recite the four components of Section 90. Which river basin contains Polavaram?

Polavaram's map point identifies a Godavari project zone. Household entitlement and transferred-village boundaries need legal and survey records at a much finer scale.

Current district geometry: APSDMA. Legal details: official 2014 and 2026 Acts and dated government records.
