About
This dataset provides crucial information regarding water resource availability in Chennai, the capital of Tamil Nadu, India [1]. Chennai is highly reliant on groundwater resources to meet its water needs and was experiencing an acute water shortage in June 2019 [1]. The dataset focuses on the water levels/availability within the city's four primary reservoirs: Red Hills, Cholavaram, Poondi, and Chembarambakkam, which collectively hold 11,057 million cubic feet (mcft) [1]. It aims to help visualise the city's water needs and usage, assess if existing sources can sustain needs until the subsequent monsoon, and compare the severity of the current water crisis with previous years [2]. Additional fresh water sources for Chennai include desalination plants at Nemelli and Minjur, aquifers in Neyveli, Minjur, and Panchetty, and Cauvery water from Veeranam lake [3].
Columns
- Date: The date of observation for the reservoir data [4].
- POONDI: Represents the water availability or levels in the Poondi Reservoir [3, 4]. The data unit is million cubic feet [3]. Statistical data for this column shows values ranging from 0.90 to 3231.00, with a mean of 1.11k and a standard deviation of 1k [4, 5].
- CHOLAVARAM: Represents the water availability or levels in the Cholavaram Reservoir [3, 5]. The data unit is million cubic feet [3]. Statistical data for this column shows values ranging from 0.00 to 896.00, with a mean of 226 and a standard deviation of 267 [5, 6].
- REDHILLS: Represents the water availability or levels in the Redhills Reservoir [3, 6]. The data unit is million cubic feet [3]. Statistical data for this column shows values ranging from 0.00 to 3300.00, with a mean of 1.59k and a standard deviation of 915 [6].
- CHEMBARAMBAKKAM: Represents the water availability or levels in the Chembarambakkam Reservoir [3, 7]. The data unit is million cubic feet [3]. Statistical data for this column shows values ranging from 0.00 to 3396.00, with a mean of 1.32k and a standard deviation of 952 [7].
Distribution
The dataset is provided in CSV format (
chennai_reservoir_levels.csv), with a file size of 243.17 kB [4, 8]. It contains daily observations over the last 15 years [3]. Each column has 6,182 valid records, corresponding to 6,182 unique date entries [4-7]. The data unit for reservoir levels is million cubic feet [3].Usage
This dataset can be used for several key applications:
- Visualising the water needs and usage of Chennai [2].
- Identifying whether current water source availability can meet the city's needs until the subsequent monsoon season [2].
- Comparing the current water crisis severity with previous years to understand trends and historical context [2].
- Analysing trends in reservoir levels and their fluctuations over time.
Coverage
The dataset focuses on the city of Chennai, which is located on the Coromandel Coast off the Bay of Bengal and is the capital of the Indian state of Tamil Nadu [1]. The time range covered spans the last 15 years, with data available on a daily basis [3]. The current dataset specifically includes data for the four main reservoirs: Poondi, Cholavaram, Redhills, and Chembarambakkam [3]. There are plans to add further data, such as water availability from Veeranam lake and rainfall levels [2].
