7 South Platte River shed Study shed Inventory Develop list of projects Small Projects Other projects Prepare Costs Estimates for Projects Permits required for Projects Funding sources for Projects Report Study to be completed in September 2017

8 shed Inventory L Use Geology, soils groundwater Hydrology - Evaluate Wet, Dry Normal Scenarios Systems (irrigation municipal) Storage Opportunities Vegetation, Crops other Natural Resources Quality Issues

9 Vegetation L Use

10 Rehabilitation Plan including the Small Projects Develop list of projects to improve watershed Small Projects Sponsored through the LCCD to receive WWDC funding Other projects can be considered during study

11 WWDC Small Project Program

12 What is a Small Project? Total Project Cost Not More Than $135,000 WWDC Cost Share not more than $35,000 Can Be Matched With Other Federal State Funds (EQIP, WWNRT, etc.) These projects must improve conditions function of the shed Provide public benefits

13 Types of Projects Eligible for WWDC Funds Small Reservoirs (less than 20 AF capacity) Well Development Pipelines Conveyance Facilities Spring Developments Wetl Developments Irrigation Windmills Solar Platforms Environmental Projects (stream bank stability, water quality, erosion protection)

14 WWDC Small Program Statewide Irrigation Projects 91 Stock Pipelines ( Tanks) 40 Solar Pumps Solar Platforms 33 Spring Developments 80 Stock Ponds 76 Wells 12 Wetl Restoration 2015 Funding for $2,000,000 projects
