IRRIGATION AND PUBLIC HEALTH DEPARTMENT
FLOOD PROTECTION WORKS
Flood Protection Works
The flood prone area in the State is 2.31 lakh ha. The Government is
making strenuous efforts to protect private properties and culturable
land by providing emergent Flood Protection measures in the shape of
embankments, spurs and wire crates etc. Upto March, 2019 the department
was able to protect an area of 24920.21 hect. from the fury of floods.
CHANNELISATION OF SWAN RIVER
District Una is situated on the bank of Swan River, which flows from
North to West direction. This river is known as river of sorrow as during
monsoon period the flood creates havocin District Una. Due to continuous
silting, the bed of Swan River has risen constantly due to which meandering
action take place. The width of the river has increased and fertile
land situated on both banks is turning barren due to silt deposits.
Besides some of the fertile land situated near the banks has been eaten
away during the floods.
Swan river has a total catchment area of 1200 Sq. Km and has a length
of 65 Kms in Himachal Pradesh. There are 73 tributaries in the catchment
area. The catchment area mainly comprises loose fragile Shivalik hills
with very little vegetative cover. During monsoons, the eroded material
in the catchment area gets moves through the tributaries to the main
Swan River.
Approximately 10,000 ha. of agriculture land is affected by floods and
annually 2000 ha. of fertile land is not being cultivated due to fear
of floods. During the past 10-12 years extensive damage to civil structures,
properties, human life and live stock has been taking place. The estimated
loss to crops and property is to the extent of about Rs. 15 crore per
annum. The task of flood management of Swan River is therefore of utmost
importance.
Swan River Flood Management and Integrated Development Project was framed
by IPH Department in 1984 and submitted to Central Water Commission,
Govt. of India, Ministry of Water Resources for techno economic clearance.
Total cost of the treatment of the catchment works out to about Rs.259
crore . After various deliberations it was decided to tackle critical
portions in the first phase.
The detailed project report for providing embankments on both banks
of Swan River in a length of 16.67 Km. as Phase-I from Jhalera bridge
to Santokhgarh bridge was prepared based on mathematical model studies
carried out by Central Water Power Research Station (CWPRS), Pune. This
project amounting to Rs. 102.71 crore was accepted by the Technical
Advisory Committee of Ministry of Water Resources, Govt. of India in
its 72nd meeting held on Jan.18, 2000. The Ministry of Environment and
Forests, Govt. of India has also accorded clearance vide its letter
No.J-12011/1.4.98-IA-I dated 9.3.2000 in the meeting held on 21.2.2000.
Investment clearance has also been accorded by Govt. of India, Planning
Commission.
For integrated approach of the project it is proposed to treat entire
catchment instead of just the sanctioned portion of 16.67 km. For this,
approval has already been received. Even prior to the clearance of this
project by the Govt. of India, Govt. of HP. has been quite concerned
about flood damages by Swan River every year. In all 42 most vulnerable
points requiring emergent flood control works were identified and of
these 40 have since been completed at a cost of Rs. 9.28 crore. An amounting to Rs. 24.57 crore have been approved under NABARD for phase-I stage-3rd (RD 6000 to 2500) .
TREATMENT OF CATCHMENT AREA
There is a provision of Rs. 75 lakh in the approved project report of
Rs.106.83 crore for treatment of catchment area of tributaries falling
from Jhalera bridge to Santokhgarh bridge, and against this provision
full amount already stands deposited with Distt. Forest Officer Una
upto 3/2003 The Forest Deptt. has planted 58500 trees, in 50 ha., of
different varieties. In addition to this check dams in the tributaries
and planting of grasses and bushes for bank protection has been done
. Further work is in progress by the Forest Deptt.

BATA RIVER
River Bata emerges as a Khala nearby village Kolar and passes through
the fertile land from Kolar to Bata Bridge and finally/ joins the Yamuna
River. The Bata river keeps on changing its course in rainy season and
is further influenced by the fall race water of Giri Bata Hydel Project,
which adds nearly 16000 Cusecs of water and it results ultimately the
erosion of land on both the banks of river. Over the years, Bata River
has been causing damage to the life and property of the inhabitants
located on the banks of Bata River.
Therefore, a comprehensive detailed project report for Bata River channelization
costing Rs.30.11 Crore has been prepared and is under process for re-submission
to Ganga Flood Control Commission, Patna.
The approval for channelisation of Bata River at (various RDs) vulnerable
reaches in Paonta Sahib Distt. Sirmour has been received from Deputy
Commissioner (ER) G.O.I. Ministry of Water Resources vide letter No.5/16/2002-ER/189-229
dated 21.1.2004 for amounting to Rs. 3.09 cr. out of which State share
is Rs.0.77 cr. and Central share is Rs.2.32 cr.
The work of channelisation was carried out at vulnerable reaches and department persuated the land holders to allow the deptt to constrct the embankment free of cost at least for the instant Project. Against the provision of 2600 mtrs. in the DPR, 3000 meters embankment has been constructed at site as such the work of channelisation of Bata River at vulnerable R.D's have been completed and amount of Rs. 3.09 cr has fully been utilised.
An amount of Rs. 2.67 cr.( GOI share is Rs. 2.00 & State share is Rs. 0.67 cr) have been sanctioned from GOI for further channelisation.
Length of protection work = 2.110 Kms. Area Protected 107 hect.
