Geocache Description:

A short 2 stages multi-cache (ppuzzle) in a quiet area of the marsh.
The first stage is a sign where you find the answers for the final.

Oak Hammock Marsh is intensively managed to mimic the natural flood and drought cycle of a prairie wetland. The marsh is divided in four sections or cells, each with its own water control structures.

To achieve its most productive stage, a marsh has to be drained out periodically to allow organic matter a chance to decay and vegetation to re-establish.

If water levels are maintained at a constant level, marsh vegetation will eventually drown and the cell may become devoid of emergent growth and pondweeds. The cell must then be drawn down so it dries out again to allow the vegetation to re-establish. It can then be re-flooded for seven to ten years before it needs another draw down.

To find this cache:

Most of the 47,000 hectare of the original St.Andrews bog has been drained. All but how many hectares of the bog was drained to form Bedson Lake?
Subtract this number from the North coordinates.

To achieve its most productive stage, a marsh must have this proportion in percentage of vegetation and open water.
Add this percentage to the West coordinates.

You should now have all the information needed to find the final cache.
