Journey to the Sea - Part II

Wetlands
8 x 8 oils

Water on earth cycles from the oceans, where it evaporates from the surface, into the atmosphere, forms clouds, falls onto the land as rain, travels through wetlands, rivers, lakes and underground then returns to the ocean — collectively known as the hydrologic cycle.

This piece is the second of a 6 part series on the journey of water to the sea. The series will be grouped together to have more impact and link the journey logically. Part I showed the origin - or one of the origins - or water. Rain.

Very close to me are wetlands, even some of my property is a wetland, home to wild ducks, mink and moose. The rain overspills its groundwater source and forms ponds and pools, eventually spilling out and creeping forward like a homing pigeon looking for the sea.

The water forms small and large rivulets that cross woodlands and meadows, soaking the ground and over time, killing trees and changing the vegetation that grows there. Where there were once trees and grass are now marsh plants such as cat tails, aquatic grasses and flag irises.
A closer view of the colours which make up the water in the painting.

The water rises and falls depending on the weather and season, but it moves relentlessly towards the sea. How does it know to flow there? Why does it cross heaven and earth to reach its destination, only to reverse the cycle all over again?

Not all water flows to the sea. There are large areas of southern Saskatchewan where the drainage is internal and water does not escape to the sea. This also happens in parts of Australia and Russia. Runoff within these internal drainage basins can produce saline lakes surrounded by white salt crusts. Dissolved salts are transported in surface and ground waters to the lakes. As the lakes have no outlet stream, the salts are trapped, and concentrated by ongoing evaporation of the lake waters.

The Journey to the sea

Flooded path sketch
9 x 12 watercolour

We don't often think about the origins ocean water and how it is continually fed by rivers and streams and rain. Its one of those things that is taken for granted without thinking about the journey from land to sea that water takes and its shape changes along the way.

It all starts with a drop of water...


While the ocean environment has conditioned every aspect of the Newfoundland and Labrador experience, the province also has ample fresh water, the source of which is abundant precipitation. More than 8% of the area of the province is occupied by lakes, slightly greater than the average for Canada, and as elsewhere water is also stored in the soil, either close to the surface where it can be used by plants or deeper in the rock as groundwater where it may be tapped by wells or returned to the surface in springs.


Besides lakes and groundwater, Newfoundland and Labrador also has many rivers. These rivers show marked seasonal variations of flow. Throughout the province peak flow occurs in late spring or early summer as the result of spring run-off, when winter snow melts and runs over the surface directly to the nearest stream. Some of the melting snow infiltrates into the soil (if the soil is not frozen), moving slowly downslope. Some of this soil water percolates deeper to the groundwater, moving even more slowly.

This Google map shows Flatrock and the abundance of freshwater ponds and lakes that are in the area. I don't think I'll have a problem with my well drying up anytime soon.

I would like to track one small trail of water as it searches for its way to the Atlantic here in Flatrock. The journey starts with groundwater, which is my water source through a well. Also the groundwater feeds some of the ponds close to my house. They in turn spill over into rivulets of water that wend their way through forest, meadows and ditches and feed my pond.

One of the wetland areas near my house is a small lane to the marsh. Its rarely dry and until the heat of summer dries up the flow, the path is like a river itself, if only a static one. I have painted this path several times and wanted to try it again, but in watercolour, to get a more delicate version of this rocky, muddy piece of semi-aquatic landscape.

I will continue to track the water as it heads towards the sea and show you where it takes me along the way until we reach the Atlantic ocean.

Fogarty's Wetland


On Sunday as I was driving along a stretch of highway, an area of wetland caught my eye and I backtracked and finally found how to locate it. Its on the doorstep of the area where I work within Pippy Park. The area is called Fogarty's Wetland and is marked with walking trails and a little bridge across the wetter area.

The Google Earthh map shows how it's cornered by highway and road - a little vestige of bog still left to be explored within the City. I have to be ashamed to say that I haven't explored Pippy Park even if I pass by it every day on my way to and from work. I can see that I need to spend some more time there.

The wetland is littered with dead trees and cat tails. Its a rather sombre palette at this time of year, as not much is green and the day was rather overcast as well. I'm always a bit timid with colours at the best of times and this piece seems rather insipid, but the dead grasses and dulled colours really do dominate this landscape.

I did a quick sketch on the spot then took that home to do an oil study. I would like to paint the same spot over time to see the changes in colour of the grasses and see the levels of the water change.
