WATER MANAGEMENT
Water Quality and River Flow Monitoring 
JAGUAR NICKEL PROJECT
Hydrological data from river flows in and 
around the JNP were used to generate the 
following boxplots. A boxplot is a standardised 
way of displaying the dataset based on the 
five-number summary: the minimum, the 
maximum, the sample median and the first 
and third quartiles:
	> Minimum (Q0 or 0th percentile): the lowest data 
point in the data set excluding any outliers, 
represented by the tick (horizontal line) at the 
bottom of the whisker (vertical line)
	> Maximum (Q4 or 100th percentile): the 
highest data point in the data set excluding 
any outliers, represented by the tick 
(horizontal line) at the top of the whisker 
(vertical line)
	> Median (Q2 or 50th percentile): the middle 
value in the data set, represented by the cross 
	> First quartile (Q1 or 25th percentile): also 
known as the lower quartile qn (0.25), is 
the median of the lower half of the dataset, 
represented by the bottom of the box
	> Third quartile (Q3 or 75th percentile): also 
known as the upper quartile qn (0.75), is 
the median of the upper half of the dataset, 
represented by the top of the box
Flow rates for the main rivers influencing the 
JNP from 2020 through to 2025 are shown 
below, along with the groundwater level for 
five wells/piezometers.  The yellow stars are 
the 2025 monthly averages. The flows of the 
water courses and the groundwater levels 
around the Jaguar site in 2025 were mostly in 
the third quartile of the historic data, as the 
rainfall was slightly above average.
