• Title: SPDSS Task 44.3 - Lower South Platte Alluvium Region Aquifer Levels - Phase 3
• Description: This Technical Memorandum was undertaken under Task 44.3 of Phase 2 of the SPDSS, and summarizes the compilation, analysis and mapping of water level data of the South Platte Alluvial Aquifer.
• Decision Support - Doc Type: Task Memorandum
• Date: 11/29/2006
• DSS Category: Groundwater
• DSS: South Platte
• Basin: South Platte
• Contract/PO #: C153953
• Grant Type: Non-Reimbursable
• Bill Number: SB01-157, HB02-1152, SB03-110, HB04-1221, SB05-084, HB06-1313, SB07-122
• Prepared By: CDM

from outside entities, the State should evaluate the data to determine if the
measurements represent pumping or non-pumping conditions. This could be
accomplished by analysis of hydrographs from individual wells and by evaluating data
eliminated from contouring in this TM.
^ The water level data presented in this TM should be used to develop continuous water
table maps of the alluvial aquifer for use as initial aquifer water levels and in model
calibration of a South Platte Alluvium Region groundwater model, being developed
under Task 48 of the SPDSS project.
