Basics
Many stream and meadow restoration projects have been implemented throughout the LTB over the past two decades. However a consistent definition of restoration effectiveness has not been defined nor have standardized methods been established to monitor and evaluate pre- and post-restoration conditions. This impedes the ability to define success for designers, funders and reviewers, and to communicate the benefits of stream restoration efforts to regulators and policy makers. In addition, the LTB TMDL and associated Lake Clarity Crediting Program heighten the need to define and standardize a simple yet representative approach to estimate the water quality benefit of stream restoration efforts.

The restoration of Trout Creek is touted throughout the Basin as a very successful restoration and is an ideal analog of an existing desired condition of Lake Tahoe restored meadow and stream complex. This research will use Trout Creek as a desired condition analog to integrate, focus and apply both simple and more complex observations and protocols being developed.

| 09/07/2017 9:14 PM | System | Objectives: This report and associated digital Stream Load Reduction Tool (SLRTv1) calculation templates are the final products for two complementary research efforts (Projects 042 and 074) funded by the USDA Forest Service Pacific Southwest Research Station using funds from South Nevada Public Lands Management Act (SNPLMA) research grants. The combined research goals were to obtain and leverage stream environment zone (SEZ) specific data to develop a methodology that estimates the average annual pollutant load reduction associated with SEZ restoration efforts. The goals of this project were to: • Apply the standardized approach of both simple and complex observations of Trout Creek to characterize pre and post-restoration stream reach condition by implementing the methodology and protocols of previously funded SNPLMA research (Round 7 and Round 8). • Develop a simple methodology for the Stream Load Reduction Tool for local resource managers to predict the relative water quality benefits (total and fine sediment load reductions) as a result of stream morphologic modifications and floodplain restoration efforts using Trout Creek and Upper Truckee River as the tangible examples. • Enable load reductions from stream restoration to be accounted for in the Lake Tahoe total maximum daily load (TMDL) and Lake Clarity Crediting Programs. |

| 09/07/2017 9:13 PM | System | Findings: • Reach scale water quality monitoring was conducted during two consecutive overbank snowmelt events (WY10 and WY11) to quantify the FSP load differences introduced to and exported from the restored Upper Reach of Trout Creek over the duration of the events. WY10 and WY11 reach scale monitoring identified significant FSP load reductions measured across the reach for each overbank event of 4.9 and 9.4 MT respectively. |

| 09/07/2017 9:13 PM | System | Management Implications: • A successful restoration of self-sustaining fluvial processes is expected to reduce pollutant inputs from chronic bank and bed erosion and increase pollutant retention on the floodplain as a result of increasing the frequency and duration of overbank flows. Significant temporal and financial requirements make the quantification of the actual long-term water quality benefit of a restored SEZ extremely challenging. The episodic nature of elevated flow conditions that cause erosion and/or inundate the floodplain means these events are unpredictable, infrequent and costly to monitor. In order to adequately capture and constrain the long term variability of the hydrology conditions that drive the water quality signal, consistent monitoring would need to be conducted for decades. • The measured reach scale load reductions and the floodplain specific sampling conducted on both Trout Creek and the Upper Truckee River provide undeniable evidence that long term FSP load reductions can be achieved as a result of successful SEZ restoration efforts. |
