Topic Sediment: Lower Middle Trinity - Harvest Surface Erosion through 2000
 
Caption:  This chart shows surface erosion (tons) by decade from harvested areas within sub-watersheds of the Lower Middle Trinity Planning Watershed. The first time period category includes data prior to 1950. The different colored bars represent tons of surface erosion per decade, while the total length of the bars show the total mass of sediment resulting from harvested areas during the period of pre-1950 to 2000. Sediment volumes are highest in the 1960's and 1970's reflecting the high levels of timber harvest in those decades. Data are from Graham Mathews and Associates Trinity River Sediment Source Analysis (2001). See Info Links for more information.
