The history of the reclamation of thisterritory goes back to the early that time all of the land was subjectto overflow to a greater or less extent,but because of the large storage area af-forded for the surplus waters the depthof the overflow was comparatively small,and reclamation was begun on the higherportions of the territory, where, at thattime, levees two to three feet high alongthe banks of the stream would keep outany ordinary overflow and enable theowners to crop the land to greater or lessextent. As time went one, however, and thestorage areas were gradually encroachedupon by the reclamationists, the floodheights increased so that the earlier levees.

In the early history ofreclamation, practically all of the leveework was done by hand work and byhorse scrapers; a great deal of the at-tempted reclamation in the lower terri-tory was done by Chinamen with wheel-barrows. There are still occasional evi-dences to be found of this old work and,in some instances, where large sloughsiwere dammed, it is a matter of wonderat the present time how so much couldhave been accomplished by hand greater portion of the soil is ofpeat formation, the peat varying in depth/rom one foot up to a maximum of aboutforty feet.
