Watershed Monitoring & Technical Support
| Program/Description |
SRWP Leads / Partners |
Funding Source / Funding Amount |
Timeline | Status |
|---|---|---|---|---|
| 1. Support Watershed Monitoring Committee | ||||
| The Watershed Monitoring Committees (formerly the Monitoring & Toxics Subcommittee) meeting bi-monthly to provide stakeholder input to the SRWP Monitoring Program and technical services they offer. The SRWP supports the Watershed Monitoring Committee by funding meeting coordination, facilitation, and note taking. The SRWP website also provides information on Watershed Monitoring Committee meetings and work products. |
SRWP Lead: Otis Wollan Tech support: Larry Walker Associates, Regional Board |
Funding Source: EPA/SRCSD Phase IX & Prop 50 CALFED Watershed Program Funding Amount: $20,000 |
Aug. 2005 – Dec. 2007 | Kathy is currently facilitating a more focused discussion within the Monitoring Committee exploring the future of the SRWP Monitoring Program. |
| 2. Support Delta Tributaries Mercury Council (DTMC) | ||||
| The DTMC meets bi-monthly to provide a forum for mercury experts and resource managers from various organizations to update each other on cutting-edge mercury research and public outreach projects. The DTMC also works to implement the DTMC Mercury Strategy which addresses gaps in mercury research, education and control measures. The SRWP supports the DTMC by funding meeting coordination, facilitation, and note taking. The SRWP website also provides information on DTMC meetings and work products. |
SRWP Lead: Mary Lee Knecht Tech support: Larry Walker Associates, Regional Board |
Funding Source: Prop 50 CALFED Watershed Program Funding Amount: $22,500 |
Apr. 2005 – Dec. 2007 | Mary Lee Knecht is funded to facilitate the DTMC. |
| 3. SRWP Mainstem River Monitoring | ||||
| The SRWP conducts extensive water quality, toxicity, and some fish tissue monitoring on 13 sites along the mainstem Sacramento River, major tributaries, and representative ag and urban drainages. In 2006 and 2007 the SRWP will conduct water quality monitoring for 9 events per year and will produce annual monitoring reports. |
SRWP Lead: Kathy Russick, LWA, Pacific EcoRisk
Partner: |
Funding Source: Prop 50 CALFED Watershed Program Funding Amount: $1,011,690 for 2 years of monitoring |
Mar. 2006 – Aug. 2007 | Contract with LWA signed. Working on contract with Pacific EcoRisk. LWA developing QAPP and monitoring plan for review by Regional and State Boards. |
| 4. On-Line Water Quality Database | ||||
| Starting in the mid-1990s SRWP began working with DWR to develop an on-line statewide water quality database. That BDAT database was launched in Feb. 2004 and included all SRWP water quality monitoring data. LWA now enters all SRWP water quality monitoring data into the on-line water quality database. |
SRWP Lead: LWA

Funding Source: EPA/SRCSD Funding Amount: Funding from several phases |
On-going | SRWP water quality monitoring data through June 2002 is currently in the BDAT database. |
| 5. Pesticide Modeling [More info] | ||||
| Develop a water quality computer model to model the environmental fate and transport of diazinon in the Sacramento River watershed. The model identifies and quantifies important regional sources of diazinon and to evaluates the feasibility of best management practices (BMPs) to reduce diazinon concentrations. The model was developed in the first phase of the project and simulations using actual diazinon application and monitoring data from 1992-2001 was conducted on the Butte Main Drainage Canal, a 38,000-acre sub-watershed. The simulations compared historical diazinon levels to simulations placing various BMPs throughout the sub-watershed based on new regulatory label changes. Substantial reductions (up to 50%) in diazinon levels were found with strategically located BMPs. These kind of modeling results can be helpful to growers in locating real BMPs on their properties. |

Phase 4 scheduled to end Spring 2007 | Work is completed. |
| 6. PRISM Grant Project [More info] | ||||
| Due to increasing regulatory restrictions on organophosphate pesticides (OPs), pyrethroid pesticides have replaced OPs for many residential and agricultural uses. There is little information on the environmental impacts and risks associated with the increased use of pyrethroids. The purpose of this study to: 1) determine environmentally levels of pyrethroids in aquatic sediments of ag- and urban-dominated waterbodies; 2) determine if these levels approach toxic thresholds; 3) promote awareness of sediment-associated pesticides and demonstrate the analytical feasibility of studying this group; and 4) provide data needed to direct mitigation efforts is they are deemed necessary. |

Funding Source: Prop 13 PRISM Grant Funding Amount: $190,000 |
Aug. 2004 – Mar. 2007 | Work is completed. |
| 7. Unknown Toxicity Study | ||||
| Toxicity Identification Evaluation (TIE) methods exist for many toxicants found in Sacramento River watershed samples. Occasionally aquatic toxicity is detected without the chemical causing the toxicity being identified due to limited TIE methods. This is a study to be done in coordination with other Regional Board studies to develop new TIE methods to identify toxicity due to pyrethroid insecticides. |
SRWP Lead: Stephanie Fong, Regional Board

Funding Source: EPA/SRCSD Funding Amount: Phase X - $91,000 + ~ $25,000 in additional funding |
Sep. 2005 – Dec. 2006 | Additional funding is in the process of being allocated to Dr. Weston's work to test the assumption that, when multiple pyrethroid insecticides have toxicity associated with them in a sample, their toxicity is additive. |
| 8. USGS Bear River Mercury Monitoring | ||||
| Conduct mercury monitoring special study on Bear River (in Nevada & Placer counties) in cooperation with USGS at four sites annually on Bear River in accordance with approved QAPP and monitoring plan. Prepare draft and final reports. |
SRWP Lead: Kathy Russick

Funding Source: Prop 50 CALFED Watershed Program Funding Amount: $99,000 |
Jan. 2006 – Spring 2007 | Project is underway. |
| 9. USGS Soil Methyl-Mercury Potential Study | ||||
| Conduct sediment manipulation studies to determine mercury bioavailability at four sites (different environments; different sediment types) annually for two years. Sites will be determined through discussions with the DTMC and after review of other studies within the Sacramento River watershed. Sediment will be subjective to different treatments including addition of sulfate, sulfide, iron (3+), iron oxide, and acetate. Methylation and demethylation rates will be determined and as will pore water concentrations of sulfate, iron (2+), sulfide, and acetate. |

| 10. USGS Monitoring of Mercury in Wetland Discharges | ||||
| Monitor water quality at 3 wetland sites where ongoing studies of mercury methylation potential and bioavailability in sediments will be performed. Water quality monitoring will provide an indication of the extent to which mercury transformation processes in the wetlands may affect downstream water quality with regard to methylmercury. Sites will be selected after discussion with the DTMC. Water quality sampling will include inflow and outflow sites. Water quality analyses will include filtered and unfiltered total mercury and methyl mercury, total suspended solids, major cations, major anions, trace metals, nutrients, and dissolved and particulate carbon. Results of the sampling will be integrated with the results of a sediment study performed by others at USGS. |
