  1. Mattabesset River Watershed Management Plan Julie Foley

  2. Watershed Statistics • 45,000-acres • 90,000 residents • 3 counties and 10 town municipalities • 1,630 acres of wetlands in the watershed Introduction

  3. Land Use • 65% zoned for residential • 18.3% impervious cover Introduction

  4. CT River Watch Program • Volunteer-based CRWP founded in 1992 • Build awareness of river resources • Collect scientifically credible data Introduction

  5. Plan Focus • Ultimate goal to restore the river to a fishable and swimmable condition. • Nine-goal management plan • Water resources • Land use • Education and outreach • Funding and partnership needs

  6. Vision Statement

  7. Water Quality Monitoring • Yearly monitoring since 1992 • Water chemistry and bacteria • Problems with bacteria, nutrients and metals • Macroinvertibrates indicate moderate to severe WQ and habitat degradations State of the Watershed

  8. TMDL • Sources of indicator bacteria include point and nonpoint sources • Stormwater runoff, animal waste, natural sources (wildlife), illicit discharges, failed collection systems, and poor septic systems. • Implementation Plan – MS4 Permits • Monitoring Plan State of the Watershed

  9. Dams and Impoundments • Multiple drinking water reservoirs • Three industrial impoundments impede fish migration • Two inactive industrial dams (cooling and hydroelectric) • One actively utilized as a cooling pond State of the Watershed

  10. Stream Walk Study Results • <25’ stream buffers are common • Most common land use adjacent to streams is suburban development • Notable stream bank erosion • Prevalent in stream algal growth • Stormwater discharge pipes causing impairments State of the Watershed

  11. Plan Implementation • District, municipalities, landowners, businesses, federal and state environmental agencies, and environmental organizations • Three Phases • Outreach and education (< 2 years) • Implement funded projects (2-5 years) • Long term follow-up projects (5-10 years) The Plan

  12. Plan Organization • Goal • State goal and problem definition • Phase • I, II and III; each has separate objective • Objective • State objectives • Supporting tasks • List tasks required to address goal The Plan
