Contouring an imported image

How can I import an image like this on MATLAB in order to produce contours of the water table level at each well represented by W?

All I have available are the water table values at each well, and the lake. There are no x and y coordinates.

I am using R2017a

As per my understanding you are trying to draw a contour plot. To do so you can map the x, y coordinates manually as per the scaling provided.

You can refer to the following link for better understanding of how to approach the problem:
