3. Surface Water Model (Hvdrosohere)
Hydrosphere has obtained STATEMOD, Hydrobase and appropriate DMI's and installed and
tested the system. They have worked with RTI on version updates and some fixes to these tools,
Development of the required water district structure lists has begun. Task 2 work includes the
identification of the study period and the data review, hydrologic analysis, drought index
analysis and development history work have all been initiated. A number interviews with ditch
companies and water commissioners have also been completed.

4. Consumotive Use Model and Water Budget (Leonard Rice Consulting and ArgO Engineering)
Argo Engineering has obtained the satellite imagery required and initiated processing and
identification of the areas associated with each ditch system. Argo has also begun collecting the
required climatic data. Leonard Rice Consulting has begun identification of non-district parcels
as well as done some climate data collection and data gap filling. Efforts to calibrate the Blaney-
Criddel consumptive use model to the Rio Grande Basin and incorporate the Hargreaves
consumptive use model into the RGDSS have also been initiated.

5. Soatial Svstem Integration and Technical Assistant (HDR Engineering)
GIS coverages acquired at this time include topography, hydrologic unit maps, and the SL V - e
GWM. These coverages are completely installed and awaiting fina1 QA\QC and documentation.
Coverages for stream gage, wells, climate stations, diversion headgates and dam and reservoir
locations are being developed from Hydrobase. Water District, Range-Township-Section,
Division 3 structures, County Boundaries, Lakes and streams, and most of the DEM's for the Rio
Grande WCD have been acquired and are being installed and checked, Well File analysis work
has been initiated.

6. Relational Svstem Integration <Riverside Technology)
Development of a general data flow overview document has been completed. RTI is currently
working on a detailed data flow document for the surface water model. The well permit files
have been put into Hydrobase so that comparisons to the water rights tabulation can begin.
Work has been initiated to add well infonnation to the DMI utilities. Assistance has been
provided to other consultants with respect to any software problems encountered in the process
of moving CRDSS elements to the RGDSS.

7, Other Activities
Twelve new stream gages and eight new irrigation diversion gages have now been installed and
agreements between the Rio Grande Water Conservation District and the State Engineer's Office
for the operation and maintenance during the 3-year development period tentatively agreed on.
An agreement between the Rio Grande Water Conservation District and the State Engineer's
Office for the long term observation of nineteen new monitoring wells has also been tentatively ..
agreed on. The computers to implement the Administration Tool for the State Engineer's Office ..
