Lower Jhimruk is a 142.5 MW JICA promising-storage candidate in the West Rapti basin. It is pinned in Layer: Storage Shortlist as a medium-basin storage option, with the important caveat that its layout conflicts with Naumure in the current design set.
Summary
Lower Jhimruk is a 142.5 MW JICA promising-storage candidate in the West Rapti basin (Karnali basin). It contributes 94.4 GWh of dry-season energy with 386 MCM total storage and 211.6 MCM effective storage. The page tracks it as a medium-basin storage option using the current JICA/NEA source set, with the noted caveat that its layout conflicts with Naumure in the current design set.

Why It Matters
Lower Jhimruk contributes 94.4 GWh of dry-season energy, with 386 MCM total storage and 211.6 MCM effective storage. It is not a top-capacity project, but it belongs in the storage shortlist because it helps illustrate the range of medium-basin options.
The caveat is central: the shortlist notes that Lower Jhimruk's layout conflicts with Naumure (W. Rapti) in the current design. That means the project should not be counted naively alongside Naumure as if both could necessarily be built in the same configuration.
Status And Timing
Lower Jhimruk is a planning candidate from the JICA/NEA storage material. The current wiki evidence set does not confirm construction start, financing, or a COD target.
The next question is scheme selection: if Naumure advances, Lower Jhimruk may become less relevant or need redesign. If Naumure stalls, Lower Jhimruk remains a smaller West Rapti storage comparator.
Map Interpretation
The marker uses an operating-project registry point near a mapped river reach as a reference. It is a planning-layer marker, not a final site boundary.

Limitations & Controversies
The current page is strongest on master-plan and shortlist context. It does not independently verify feasibility-study details, environmental and social assessment, financing plan, grid-connection commitment, or construction timeline beyond the existing source set. The layout conflict with Naumure means the project should not be counted naively alongside it as if both could necessarily be built in the same configuration. Map markers are planning-layer references, not final site boundaries.
