| Topic | Sediment: Lower Trinity - Harvest Surface Erosion through 2000 |
| Caption: This chart shows surface erosion (tons) by decade from harvested areas within sub-watersheds of the Lower 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 from surface erosion resulting from timber harvest during the period of pre-1950 to 2000. Sediment production after the 1979 period in the Lower Trinity watershed has been dramatically lower, which is attributed to a combination of lesser amounts of harvest on the USFS land. Data are from Graham Mathews and Associates Trinity River Sediment Source Analysis (2001). See Info Links for more information. | |
