1. Working with Irrigation Entities in Idaho Presented by Linda Davis Date March 2012

2. Identify areas that need to be updated Assess needs of NHD users Educate and Inform Work with local sub-stewards to get best information Provide tools and data Follow up and support

3. Identify areas that need to be updated Many areas represented well with NHD Some areas have had changes to Hydrography since initial line work was collected Urban Areas Areas affected by agriculture and water delivery

4. Irrigation Companies Urban Areas

6. Vertical Relationships Underground features Connectivity

7. Missing canal

8. Assess needs of NHD users National and regional users want updated line work for a variety of applications. Water accounting Fish passage Flooding Modeling Local water managers need updated line work to help manage water delivery, notify customers of problems in water delivery and canal maintenance.

9. Educate and Inform Worked with BOR to get GIS software to Irrigation Entities Met with Irrigation Entities and told them about the NHD and how it can be used to assist them Provided Irrigation Entities with maps of hydrography with Imagery within their service area. Worked with Irrigation Entities to show them tools that work with NHD – HEM tool

10. Work with local sub stewards to get best information Obtain contacts of interested sub-stewards (irrigation entities) Work within their time schedule Get any existing base material – old service maps, or diagrams Photo revise NHD for area of interest with 1 meter NAIP (2006, 2009, 2011)

11. Provide tools and data Provide Irrigation entities with maps of service area Provide tools that will allow them to edit hydrography Online editing tool Arc based tool

13. The Arc Based Tool Was used by the Burley Irrigation District, the Northside Irrigation District, American Falls Reservoir District #2, the Big Wood Canal Co and Water District 37. The Northside Canal Co. uses the line work along with their head gate information to improve customer service response time. (A customer comes in with a problem at their head gate, can be traced upstream and correct ditch rider notified. American Falls Reservoir District #2/Big Wood Canal Co. are using the line work to help plan system projects including ditch to pipeline conversions. They are also using the line work with a student GPS data collection project that involves collection of head gate information. The HEM tool was used by the Burley Irrigation District to attempt to link parcel centroids to the NHD

14. Follow up and support Gotomeeting (web based like webex) In house training HEM training General GIS support
