| Topic | Sediment: Upper Middle Trinity - Sediment Inputs Percent 1981-2000 |
| Caption: This chart displays the relative proportions of total sediment inputs summarized by management and non-management sources for sub-watersheds within the Upper Middle Trinity Planning Watershed between 1981-2000. Management related erosion sources consist of mass wasting (landslides), fluvial, and surface erosion processes that are related to timber harvest, roads, and mining activities. Non-Management related erosion sources include landslides from forested areas, bank erosion, and soil creep. Management related sources exceed non-management sources in all sub-watersheds except Deadwood Creek, Rush Creek, and Weaver Creek. These sub-watersheds are dominated by non-management; however, management and legacy management sources contribute significant volumes of sediment. The non-management erosion yield does not necessarily represent long-term background rates due to yearly variations in the degree of wetness. A detailed breakdown of sediment source components is available in the Chart and Source tables. Data are from Graham Matthews and Associates Trinity River Sediment Source Analysis (2001).
