Basics
When a forest is disturbed, surface runoff may increase, generating surface runoff and sediment delivery. In some cases, such disturbance can also release nutrients like phosphorus to runoff and subsurface lateral flow, adversely affecting offsite water quality. If there is no forest management, then the risk of wildfire is increased, as is the probability of elevated erosion rates much greater than those associated with disturbances from forest management.
There was a need for a tool that could predict the impacts of wildfire and compare that to the impacts of fuel management activities. This project was designed to provide such a tool at a sub watershed scale.

-
Lake Tahoe, widely known for its clear waters, has started to experience during the last 50 years problems related with reduced transparency. Long-term water quality monitoring at the outlet of the Lake’s main tributaries suggested an increase in sediment and nutrient (nitrogen and phosphorus) delivery to the Lake, which has contributed to the decline in water clarity. Urban development and changes in land use and land cover are the main sources of direct pollutant input to the Lake, but other factors such as atmospheric deposition have also been responsible for the Lake’s nutrient enrichment.

| 08/15/2017 8:19 AM | Kiara Cuerpo-Hadsall | Objectives: We propose to meet with stakeholders in the basin to determine the current fuel management activities. We will then develop watershed tools to allow mangers to evaluate the subwatershed effects of these activities in terms of fine sediment and phosphorus delivery from subwatersheds that were treated. |
||
| 08/15/2017 8:19 AM | Kiara Cuerpo-Hadsall | Findings: We have developed a way to use the current predictions within the WEPP technology to estimate not only the surface runoff and sediment delivery, but also delivery of fine sediment below a user-specified threshold, and phosphorus through both surface and subsurface lateral flow pathways. |

| 08/15/2017 8:18 AM | Kiara Cuerpo-Hadsall | Management Implications: Use of the WEPP tool will allow managers to dynamically fine tune their projects to maximize the efficiency of BMPs designed to protect water quality. Publications: |
