  2. Northglenn Westminster Arvada Wheat Ridge Lakewood Englewood Littleton Q: Where? A: 850 Sq. Miles Touching 6 Front Range Counties • Population: 2.5 Million (1 in 2 Coloradoans) • 90% Privately Owned • 35% Residential, Industrial, & Commercial • 49% Agricultural • 500 Miles of Streams & 550 Miles of Canals

  3. Q: Who? • City of Aurora • City & County of Denver • City of Thornton • Denver Water • East Cherry Creek Valley • S. Adams County Water & Sanitation District • United Water & Sanitation District • Littleton/Englewood Wastewater Treatment Plant • Metro Wastewater Reclamation District • S. Platte Coalition for Urban River Evaluation • Farmers Reservoir & Irrigation Company • Barr Lake State Park • Pelican Lake Ranch Development • Potentially Another 2,449,987 Residents A: Barr/Milton Watershed (BMW) Association Cities Drinking Water Wastewater Recreation

  4. - Problem- Sources- Solution Q: What? A (problem): Cultural Eutrophication – over loading of nutrients from human sources that lead to water quality issues. A (sources): Point Sources – pollution discharged from specific, identifiable pipes or points, such as industrial, stormwater, agricultural, or water treatment facilities. Nonpoint Sources – pollution that cannot be traced to a specific origin such as atmosphere, groundwater, sediments, and stormwater. A (solution): Determine appropriate water quality for the water uses in Barr and Milton. Decide what human-related nutrient reductions are needed. Implement a integrated, cooperative plan.

  5. Q: When? Summer 2008 A: Now & Ongoing • Two Reservoir Assessments • Watershed Modeling • In-reservoir Modeling • Start pH TMDL Work Summer 2010 • Develop 3rd- Party pH TMDL • State-defined Nutrient Standards

A: 2.5 Million Residents May Need To Change Their Ways Examples

  8. Symptoms Problem Poor Clarity High pH Low Oxygen Excessive Nutrients (Phosphorus Nitrogen) Algae Blooms Taste/Odor Aesthetics Fish Kills Reflections Cultural Eutrophication Eutrophication is natural for lakes. For Barr and Milton, this process is sped up because they are reservoirs and the watershed is heavily used.
