  1. BMWAssociation 2006 Barr Lake and Milton Reservoir Watershed Management Plan Presentation to the Colorado Water Quality Control Commission May 14, 2007 Alice Wood Watershed Coordinator

  2. ~ Brief History of the Reservoirs ~ Overview of the BMW Association ~ Outline of the 2006 Watershed Plan ~ Next Steps Overview

  3. Orientation Bigger Picture:Downstream to the Mississippi River Basin Barr Lake Milton Reservoir DIA Rocky Mtn. Arsenal Where are you now? South Platte Watershed

  4. Milton Res. Big Dry Creek Barr Lake 1st, 2nd, & 3rd Creek Standley Res. Clear Creek Sand Creek S. Platte River Cherry Creek Bear Cr. Res. Bear Creek Marston Lake Cherry Cr. Res. Chatfield Res. Creeks, Rivers, and Reservoirs Aurora Res.

  5. Watershed Boundary • Barr Lake • 33,100 AF • 1,870 Acres • 37 ft Max. • 260 Day Residence Time • Receives both S. Platte River and treated effluent water • Milton Reservoir • 31,000 AF • 2,000 Acres • 41 ft Max. • 393 Day Residence Time • Receives water mainly from Platte Valley Canal & Beebe Draw Barr/Milton Watershed

  6. Reservoir Management • Owned by FRICO (Farmers Reservoir & Irrigation Company) • Main Use - Agricultural Irrigation • Other Uses - Drinking water, Recreation, Aquatic Life Habitat • Filled during the winter and early spring • Released during the growing season (May – September)

  7. Symptoms Problem Aesthetics Poor Clarity Low Oxygen Excessive Nutrients (Phosphorus, Nitrogen) Algae Blooms Fish Kills Taste/Odor High pH Water Quality Issue Eutrophication caused by excessive nutrients (phosphorus and nitrogen) leads to many undesirable water quality symptoms.

  8. Barr Lake Chl-a and Total Phosphorus 500 1800 450 1600 400 1400 350 1200 Chl-a 300 Chl-a (ug/L) 1000 TP TP (ug/L) 250 800 200 600 150 400 100 200 50 0 0 Jun-02 Jun-03 Jun-04 Jun-05 Jun-06 Barr Lake pH (1.0 meter below lake surface) 12 pH 11 Upper pH Standard 10 9 pH 8 7 6 Jun-02 Jun-03 Jun-04 Jun-05 Jun-06 Desirable TP = <50 Chl-a = <30 pH = 6.0 - 9.0

  9. Source of the Problem Source Solutions Fertilizers Use less on Lawns Pet Waste Properly Dispose Wastewater/Industry Upgrade Treatment Stormwater Cleaner Streets Runoff Conserve Water Farms Proper Land Management Feedlots Riparian Fencing/Waste Management Emissions Reduce air pollution Erosion Stream Restoration Everybody within and upstream of the Watershed contributes in some way to the loading of nutrients to Barr Lake and Milton Reservoir. Collectively, everyone can be a part of the solution.

  10. BMW Association Mission to encouragecooperation, involvement, and awareness by all interested parties incollaborativeefforts toimprove the water qualityof Barr Lake and Milton Reservoir.

  11. BMW Association Water Quality Goals • Meet all State water quality standards • Ensure that plans & actions will maintain or improve water quality & habitat • Develop water quality models • Define site-specific, numeric, & narrative water quality targets • Recommend to the State an appropriate TMDL allocation plan

  12. BMW Association • Planning Group started in Early 2002 • Based on WQCC request at SP Triennial review (2000) • 303(d) listing for pH (2002) • FRICO, Metro, Thornton, CDPHE, Littleton, Englewood, Denver • Phase 1 Non-Point Source State Grant 2004 ($41,100 grant, $27,400 match) • Form Nonprofit Association • Establish Directors, Committees, Annual Tour, Annual Meeting • Build Water Quality Database (330,000 records from 360 stations) • Phase 2 & 3 Non-Point Source State Grant 2005 ($301,900 grant, 90% match required, $2,724,100 match pledged) • Hire Watershed Coordinator • Conduct Reservoir Assessments • Write Watershed Plan • Build Water Quality Modeling • Develop pH Total Maximum Daily Load (TMDL)

  15. wa∙ter∙shed plan (wô ́tər-shēd΄ plăn) n. A strategy that provides assessment and management information for a defined watershed that will lead to measurable results and an overall improvement in water quality and watershed conditions. The process is iterative, holistic, and collaborative.

  16. Watershed Plan -Sections • Watershed Characterization:Inventory of Important Features • Partnerships & Organizational Structure:Integration with other Groups • Scope of Watershed Efforts:Identify Pollutants, Sources and Goals • Information Sources, Monitoring, and Data:Data Inventory • Data Analysis:Modeling, Strategies, Estimate Pollution Reduction Amounts • Watershed Management Action Strategy:Management Efforts to Improve Conditions • Implementation:Measurements of Progress and Success • Adaptive Watershed Management:Iterative Management Approach

  17. Watershed Plan The Numbers 98% of BMW is Privately Owned 55% of the Watershed Supports Agricultural Uses 50,000 Head of Beef Cattle in Weld, Adams, and Arapahoe Counties 60,000 Dairy Cows in Weld County 38% of the Watershed is Urban 2.5 Million People now with Projection of Nearly 4 Million by 2030 17,000 Acres - Rocky Mountain Arsenal is the Largest Open Space 10,000 Permitted Gas & Oil Well Sites 9 Drinking Water Withdrawal Locations Along the S. Platte River 42 Major Permitted Dischargers 20 Stormwater Permit Holders 500 Miles of Streams & Rivers 550 Miles of Canals & Ditches 7 Endangered Species & 11 Threatened Species

  18. Watershed Plan The Pictures

  19. Watershed Plan –WHY? $ Save Money More Control Less Headaches Improve Water Quality

  20. Watershed Plan –HOW? Guidance:Assist with TMDL & Nutrient Criteria Development To-Do-List:Annual Action Items to Stay on Schedule Score Card:Track what Works and what Doesn’t Example:Model for other Watershed Groups and TMDL Efforts Coordination:Manage the Stakeholders Referee:One Common Voice for all Stakeholders Education:Engage and Involve Stakeholders in the BMW Watershed

  21. Targeted outreach by Board members and stakeholders • to date: 12 presentations, ~ 250 people • at least 7 more presentations scheduled Watershed Plan –Education/Outreach Education:Engage and Involve Stakeholders in the BMW Watershed

  22. Next Steps –Schedule Modeling (2006 – 2008) pH TMDL Development (2008 – 2010) Adopt Nutrient Criteria (2009) TMDL Implementation (2011 – 2016) TMDL Evaluation (2016 – 2022) Revise Watershed Plan (Annually)
