Storm Water Management Program Monitoring & Sample Analysis Plan

Northern Nevada Water Planning Commission December 5, 2012

Truckee River Watershed Coordinated Monitoring Program

Began: Memorandum of Understanding (13 groups); 18 month process of sharing programmatic information; Product: Compendium of Truckee River Watershed Monitoring programs; Evolved: Desert Research Institute Funding by Truckee River Fund Surface water monitoring Benefits: TMWRF, SWPCC, NDEP, PLPT, Flood Project/restoration.

Truckee River Info Gateway

• Identified by NV as the clearinghouse tool for sharing

program information on coordinated efforts;

• TRIG: www.truckeeriverinfo.org

– going to the next level…

• Data housed/linked:

SWPCC, NDEP, TMWA, TMWRF, WC DWR creek data, TRWC, PLPT, USGS, T-TSA, DRI/TMWRF/DEP Coordinated program efforts…

Sample Analysis Plan: a public process

• Stantec

was selected to assist in the development of the 2012 plan, based on 2010 permit requirements;

• Public meetings and Workshop

– Attended by committee members, citizens, PLPT representatives and staff;

• A Consensus Model was used to develop the

approach and priorities for the Plan;

• Accepted by Nevada Division of Environmental

Protection in November 2012,

• Implementation to begin in January 2013.

Storm Water Monitoring Goals

• Continuing:

Characterize both background WQ & rain event WQ in the major tributaries to the Truckee.

• New: Collect the data

necessary to improve

• ur understanding of

SW effects on 303(d) & TMDL listings on the Truckee and its tribs.

• Moving ahead:

Measure the background & rain event WQ in selected

• utfalls, catchments &

land use types.

• Conduct special studies

& investigations as the needs arise & funding is available.

Tributary Monitoring continue at existing locations

• Semi‐annual sample collection (scheduled),
• Rain event grab samples (wet weather),
• Typically sample site selections are upstream

and downstream of urbanized areas on 6 tributaries.

12 Tributary Monitoring Locations

• Steamboat Ck @
• Rhodes Rd,
• The Narrows,
• Clean Water Way.
• Whites Creek @
• Timberline Road,
• Old Virginia Hwy.
• Chalk Ck @
• Chalk Bluff
• North Truckee Drain @
• Orr Ditch,
• Kleppe

Ln.

• Thomas Creek @
• Timberline Road,
• S. Meadows Pkwy.
• Alum Creek @
• Above Steamboat Ditch,
• The Truckee River.

Outfall Monitoring (10 sites)

• Alum at Chrissie

Caughlin Park;

• Oxbow Nature Park;
• Dickerson Rd.,
• Wingfield

at Arlington (north side),

• Wingfield

/ Island at Arlington (South side), Fisherman’s Park II,

• Paradise Park / Galletti

Way,

• Mary Wahl Ditch,
• Cottonwood Park

(west),

• Greg Street (East)
• GOAL:

Understanding runoff from various land uses: Industrial, Commercial, Residential, Agricultural, Urban.

Considerations / Challenges

• Traffic Control;
• Environmental and human safety;
• Seasonal challenge: frozen or dry?
• QA/QC Plan includes protocols to be used, holding

times, chains of custody, sample labeling and handling,

• Storm discharge forecasting to capture entire

hydrograph in specific tributaries

Special Studies

• Boynton Slough Watershed Characterization
• Alum Creek Watershed Characterization
• Sparks Marina Inflow Study

Tech memo/evaluation of data

• First task: Comprehensive

Literature review, evaluating NV

303 (d) listed streams/pollutants;

• Next: Propose to exclude

constituents that are found not a

result of storm water influence;

• Monitoring program developed

to address the constituents remaining which MAY be from storm water;

• SAP has been approved by the

State.

• Implementation begins in 2013

Watershed Management

• 2012 Tributary Assessment

an annual watershed tool (since 2005);

• Available on TRIG

at Truckeeriverinfo.org;

• Stems from Watershed Management Plan of 2003;
• Fire restoration sites included to provide lessons

learned and illustrate success stories;

– Caughlin Fire, Washoe Fire

• Benefits:

– Useful for Community Development processes, – Useful in drainageways evaluations and projects, – Assist in identifying/prioritizing special studies, – Helpful identifying locations of noxious weed infestations, – Help in understanding of hydromodification

• f streams.
