krishna river temporary allocation ap & ts
2016: TS government has decided to seek 402 tmc ft of Krishna.
AP argued to give powers to TRMB to allocate,
june 13 2016:
KRMB: told TS and AP to continue with the sharing of water as per the Bachawat Tribunal (1976), at least till the next one month during which period the two states would have to try and sort out all outstanding issues.
in other words KRMB decided allocation of water which has no power.
As per the Bachawat Tribunal, AP gets 512 tmc ft of water and TS 299 tmc ft of the total allocation of 811 tmc ft.
KRBM has only regulatory powers and no power to allocate waters or take control of projects.

Telangana CM K Chandrasekhar Rao, Andhra Pradesh CM N Chandrababu Naidu
harish rao said as per bachawat award 45TMC from polavaram to nagarjuna sagar in leigu of adding 80TMC godavari water to krishna basin.

pothireddypadu project height issue 2020
2005 ysr go170, 11000 cusecs 44000 cusecs (then all ts ministers resigned & disputes on tribunals)
2020 ysj go 203 44000 cusecs to 80000c usecs
102 TMC (40 TMC for Telugu Ganga Project, 38 TMC for GNSS and 19 TMC for SRBC) in 30 days
possible at 880 feet water level and at 854 feet level, only 3,000 cusecs could be discharged
almatti dam height increase
holding capacity of the Srisailam reservoir 308 TMc in 2011, and 215 TMC due to silt formation.
telangana objections on pothireddypadu >>height 805:
srisailam & nj sagar has water sharing.
Main objection by harish rao: draining water from Srisailam project at Height level 805 instead of 854.
how you take daily 80K cusecs at from srisailam 805 height level and rayalaseema ethiportha project daily 3 TMC
(hyderabad water & other projects depended on srisailam via nj sagar).
- temporary allocation 512 vs 299 (already disputes in the tribunals)
- krishna river length 415KM AP vs 482 Telangana
nagarjuna sagar 312 TMC need flow from srisailam. if you drain water 805 level from srisailam how nagarjuna sagar fulfill drinking water to hyderabad.
sagar left canal have 6l akhs acre irrigation land & AMRP project under construction palamuru, dindi,
Even SLBC (sagar left branch canal not gets water ) slbc tunnel (right canal for ap).
if you planning for flood water, then pothireddypadu sea level is 841 then 805 would be violation
object 805 instead of 854(rayalaseema ethipothala project)
