Irrigation return flows and Snake River reach gains for calibration of Eastern Snake Plain Aquifer Model Version 2. ESPAM2 design document DDW-V2-15 Item Info

This report is a Design Document for the calibration of the Eastern Snake Plain Aquifer Model Version 2 (ESPAM 2). Its goals are similar to the goals of Design Documents for ESPAM 1.1: To provide full transparency of modeling data, decisions and calibration; and to seek input from representatives of various stakeholders so that the resulting product can be the best possible technical representation of the physical system (given constraints of time, funding and personnel). It is anticipated that for some topics, a single Design Document will serve these purposes prior to issuance of a final report. For other topics, a draft document will be followed by one or more revisions and a final "as-built" Design Document. Superseded Design Documents will be maintained in a "superseded" file folder on the project Website, and successive versions will be maintained in a "current" folder. This will provide additional documentation of project history and the development of ideas. Reach gains were used to calibrate modeled aquifer recharge and discharge in cells representing five reaches of the Snake River above Minidoka. Reach gains used for calibration of ESPAM2.0 are the best estimate of river gains or losses from or to the Eastern Snake Plain Aquifer (ESPA), and may differ from reach gains used in other applications (i.e. water allocation) that include surface water contributions to natural flow. Reach gains in three reaches of the Snake River between Kimberly and King Hill were also used to calibrate modeled spring discharge. Groundwater contribution from the south side of the Snake River (outside of the ESPAM model domain) was deducted from the Kimberly to King Hill reach gains. Calculation of reach gains between Kimberly and King Hill is described in detail in Design Document DDW-V2-14 and is not covered in this document. This Design Document describes the irrigation return flow monitoring network, analysis of irrigation return flow data, assignment of return flows to ESPAM2 irrigation entities and Snake River reaches, and calculation of reach gains for five modeled reaches of the Snake River upstream of Minidoka. This Design Document incorporates ESHMC meeting discussions in May and June 2011, and supporting data analyses completed by IDWR staff.
