  1. Mountain Counties Region Karl Winkler, Chief, Central District Division of Planning and Local Assistance Department of Water Resources

  2. Setting • Western Slope of the Sierra Nevada, 43 inches annually, elevation plus snow pack, high elevation 18 MAF/yr avg. R.O. (orographic, elevation, hydroelectric, gravity, quality) • Counties –Lassen, Plumas, Butte, Sierra, Yuba, Nevada, Placer, El Dorado, Amador, Alpine, Calaveras, Tuolumne, Mariposa, Madera, and Fresno • Rivers – Feather, Yuba, Bear, Rubicon, American, Cosumnes, Mokelumne, Calaveras, Stanislaus, Tuolumne, Merced, Chowchilla, Fresno, and San Joaquin – DAU and PSA • Urbanization – growth rate 10% vs. State average 7%; 157 TAF urban, 390 ag • Population 541,710 increase to 840,025 by 2030; density; income

  3. Setting (continued) • Exports/Relationships with other regions – SWP, CVP Friant-Kern , EBMUD, SFPUC • Reservoir Capacity – 18,000 TAF, 10 MAF snow pack • Area importance confirmed by creation of Sierra Nevada Conservancy and inclusion as an overlay area in the State Water Plan • Sierra Nevada region - 65% of California’s water; 3,500 plant species; 720 species of animals; about 100 sensitive species; 50% of the State’s annual timber; and 50 million visitor days/yr; S. Yuba & NF American included in Wild and Scenic • 39 Detailed Analysis Units, 3 Planning Sub-Areas

  4. Important Considerations • Climate Change • Delta • Integrated Water Management Planning • UWMP & GWMP • Flood Control, stormwater projects, non project levees and other works • Governor’s Proposal • Agencies with statutory authority and mandatory plans • In basin and out of basin use 16 MAF vs 500 TAF urban + ag • Recognized overlay area uniqueness • Increased need for data • Disadvantaged communities • Drought planning

  5. Challenges • Regulation of ditch water – no cooking, drinking, brushing teeth • Some ditches, flumes and pipes – 100 yrs old • Second homes – variable demand; land ownership private federal low urban percentage • Fractured rock groundwater – less than 10% of supply • Penn Mine, Mercury, erosion from flooding, logging and development • Sedimentation and nutrients a concern for salmon -Stanislaus, Tuolumne, and Merced • Water supply reliability for numerous water systems

  6. Challenges (continued) • Customer base is small and low housing density • 300,000 increase in population by 2030 • Mountain topography • Limited management strategy for banking and interconnections • Large number of small isolated systems • Open ditch systems are old with seepage and evaporation • Repairs are difficult because leakage supports vegetation and wildlife • Forest fires damage flumes/ erosion / nutrients /algae • Climate change potential 36% reduction in snow pack within 100 yrs.

  7. Regional Planning • Water Forum Agreement • Regional Water Authority • Cosumnes, American, Bear, and Yuba IRWMP • Yuba Accord - 17 conservation groups, agricultural interests, and state and federal agencies • Sierra Nevada Ecosystem Study – Mountain Range Management • Sierra Tahoe IRWMP

  8. Regional Planning (continued) • NCWA IRWMP • Upper Feather River IRWMP • Yuba County IRWMP • Mokelumne / Amador / Calaveras IRWMP • Madera County IRWMP • Natural Heritage Institute Sierra Meadows IRWMP

  9. Regional Planning Participants/Plans • Categories : lead, member agencies, supporters, educational partners • Statutory and non statutory involvement • Mandatory Plans – FERC, General Plans, UWMP, GWMP, Ecosystem Restoration Plans, Fire Plans, Forest Plans, WQCP • Watershed recognition • Consideration of both in basin and out of basin use

  10. Cosumnes, American, Bear, and Yuba Integrated Regional Water Management • Non-statutory planning: vision; guidance; objectives • Incorporates statutory documents: General Plans; Forest Service Plans FERC relicensing agreements; UWMP; and Regional Water Quality Control Plans • Eligibility requirement for Prop 50 & Prop 84 • Agencies involved El Dorado Irrigation District, Nevada Irrigation District, Georgetown Divide PUD, Placer County Water Agency, El Dorado County Water Agency • Mandatory Plans - 10 FERC plans, 4 General Plans, 4 UWMP, 13 ecosystem, fire, water quality and strategic plans

  11. Looking To The Future • Climate change • IRWMP – Evolving planning methodologies • Flood Management • Recreation and Data Management • Implementation CEQA/NEPA, Regulatory, FERC • Water supply, financial resources, topography, multi-interest environmentally rich area, fractured rock aquifers • EID – Alder Reservoir/2.5 mile ditch lining • Temperance Flat • FERC licenses for 100 hydroelectric projects

  12. Looking To The Future (continued) • Regional planning support from the Mountain Counties Water Resource Association • TUD – Lyons Reservoir Expansion • Urban growth 1800 homes/yr in Lincoln/NID, Placer, City of Lincoln • South Sutter Water District’s Canal Improvement Plan • Recycled Projects • EID 5000 AF storage • Auburn 5000 AF AG use proposal by 2020 • Angels Camp 300 acre feet • Calaveras County 470 acre feet • Groveland 425 acre feet • Sierra Conservation Center/Tuolumne County 300 acre feet

  13. North Lahontan Region Karl Winkler, Chief, Central District Division of Planning and Local Assistance Department of Water Resources

  14. Setting • Extends 270 miles from Oregon to Mono County • Western Boundary of the Great Basin including Nevada and parts of Utah • All surface waters drain eastward • 6,122 sq. mi. or 4% of California • Includes portions of Modoc, Lassen, Sierra, Nevada, Placer, El Dorado, Alpine, Tuolumne, and Mono

  15. Setting (continued) • High Desert and mountain crests to 11,000 ft. • 24 Groundwater basins, 13 shared with Nevada and one with Oregon • 99,000 people in 2000 - .25% of State 2030 – 30,000 more • 40 TAF Urban, 475 TAF Ag • Tourism and recreation principal economic activity • Lake Tahoe is the largest reservoir

  16. Regional Activities • Tahoe Sierra Integrated Regional Water Management Plan – Approx 40 Partners, Educational, Nonprofit , and Supporting Agencies; forest and fire • Over 50% served considered disadvantaged • South Tahoe Public Utility District – UWMP, GWMP, Drinking Water Quality Management Plan • Squaw Valley Water Management Plan

  17. Regional Activities (continued) • Martis Valley GWMP • Markleeville Revitalization Plan Watershed and Habitat Plans • Tahoe Regional Planning Agency – Habitat Conservation Plan, Muti-Species Conservation Plan, Regional Planning • Truckee River Watershed Council • Truckee River Water Users Group

  18. Truckee River Operating Agreement • California, Nevada, TMWA, USBR, Tribe • Enhance water management flexibility, water quality, endangered species, recreation, drought supply and in stream flows • California – Nevada allocations Tahoe Basin – 23,000 AF CA and 11,000 AF NV • Truckee Basin 32,000 AF of which 10,000 AF is Surface Water for Ca and the rest Nevada

  19. Challenges • Northern portion chronic shortages – dry years limited acreage – groundwater problematic - capacities diminish rapidly during dry conditions • Truckee River Operating Agreement – finalization – implementation • Walker River – litigation/Walker lake flows and salinity (13000 ppm TDS)/LCT • Septic tanks Susanville, MTBE contamination Lake Tahoe/STPUD, Truckee River TMDL LRWQCB, Tahoe clarity – nutrients and road maintained • Road Maintenance • Watershed management USFS’s Lake Tahoe Basin Management Unit

  20. Looking To The Future • Representation for Walker River • Implementation for TROA • Coordination with federal watermasters Truckee, Carson, Walker • Some need for municipal and irrigation systems for the northern portion • Honey Lake and Long Valley GWMP to be managed; Surprise Valley (Modoc) GWMP development • Regional Planning Prop 84 and Prop 1E • Climate Change and Data Management
