RGDSS_SurfaceWater_ScopeOfWork

• Title: RGDSS Surface Water Scope of Work
• Description: The objectives of this scope of work are as follows: 1)‎ To apply and enhance an existing data centered surface water modeling system to the San Luis Valley that interacts with the State's central database ‎(HydroBase)‎ and other RGDSS planning tools. 2)‎ To calibrate and test, via application, a San Luis Valley Surface Water Model that, is 100% data centered. 3)‎ To coordinate and share the surface water investigations with SLV water users, the State, a technical subcommittee and other RGDSS contractors.

TASK 1 Obtain a Local Copy of StateMod, HydroBase and
Appropriate DMI's
Objective
Obtain a local copy and develop understanding of StateMod and supporting electronic tools
and data.
Comment
Copies of electronic files, including StateMod code and executable, DMI's, and other tools
and files will be maintained on Hydrosphere's computer system utilizing the same directory
structure as currently in place on the State's computer system.
The **State** will provide a list of structures explicitly included in the State's San Luis
Valley Ground Water Model.
Approach
1.1 Obtain StateMod and DMI's
Obtain a copy of StateMod, the Division 3 portion of HydroBase, and appropriate DMI's
from the State's FTP site. This software and data will be utilized on Hydrosphere's computer
system. No deliverables are defined for this Sub-Task.
1.2 Review StateMod and DMI's
Operate and exercise these components as necessary to become familiar with them and
prepare them for use in subsequent Tasks. Focus on review of existing operating rules of
StateMod in preparation for modeling the complex administration practices in the Rio
Grande Basin. No deliverables are defined for this Sub-Task.
1.3 Develop Preliminary List of Key Structures
Develop a preliminary list of key surface diversions and reservoirs (Key Structures) in the
Rio Grande Basin, i.e. those structures that will be explicitly represented in the surface water
model. Identification of key structures will begin by executing the DMI watright with a -
report option to generate a sorted list of total decreed surface water and storage right amounts
by structure for Division 3. The preliminary list of key structures will then be generated
based on such criteria as total decreed surface diversions (e.g. 75%), a minimum volumetric
decreed amount (e.g. 10 cfs), and a minimum irrigated acreage (e.g. 250 acres). The
deliverable for this Sub-Task will be 9 preliminary list of key structures in the Rio Grande
Basin; one for the entire division and one for each of the 8 water districts. The list of key
structures will be used, and possibly refined, during Task 4 meetings with local water
interests. Key structures will be represented in Phase la model development. The remaining
surface diversion structures will be aggregated and represented in Phase lb model
development while ground water use will be represented in the Phase lc model development.
