Population growth, increasing demands for water and energy, reduced surface and ground water supply reliability, climate uncertainty, extreme weather events, decline in critical ecosystems services, changing regulatory environments and the need for sustainable food security for our global population have created an increased need for integrated, scalable, system-level water resources planning solutions.

Lynker is leading the development and implementation of integrated water resources planning solutions to help our clients manage these kinds of complex environmental challenges, where active management of the built and natural components of the water cycle are key to water sustainability.

Central Resources Allocation Model (CRAM)™

Lynker’s proprietary Central Resources Allocation Model (CRAM™) is a water resources simulation tool used to support decisions for short, medium, and long-range planning of raw water supply system. Through an intuitive drag and drop user interface, CRAM simulates all components of the system including reservoirs, water rights, wells, diversions, exchanges and a variety of other components. CRAM provides a more complete understanding water supply and demand as well guidance for how to optimize the use of limited resources and is an ideal tool for decision-makers such as water resources managers, planners, engineers and accountants. The model is currently used by a number of cities, states, and government agencies throughout the United States for water resources modeling and decision-making.

MODFLOW Numerical Groundwater Modeling

Lynker provides groundwater analysis and modeling services to a range of clients across the western US. Our team has the groundwater modeling experience necessary to develop and implement integrated conceptual and numerical models of the groundwater system. Our modeling experts have a strong scientific background to support the nuanced decision-making that comes with model selection. Modeling is designed to obtain information on sources of recharge, estimates of recharge rates, flow paths, flow rates, sources of solutes, surface water/groundwater interactions and vulnerability assessments.

Water Supply and Runoff

Lynker has conducted and published several studies focused on the hydrologic impacts of climate change, including a major study for the State of Colorado. We collaborate closely with the National Center for Atmospheric Research on this work. In addition, we have great familiarity with selecting appropriate future climate scenarios and Global Climate Models for hydrologic impact work, and are very familiar with the results and guidelines coming from the Intergovernmental Panel on Climate Change. We also have great expertise working with the Variable Infiltration Capacity model for working with spatially distributed hydrologic modeling systems that are able to take outputs from Global Climate Models.
Our clients look to Lynker to provide cutting-edge technical capabilities in the field of hydrology for water supply planning. We have extensive experience with the use of paleo reconstructed hydrology and stochastic hydrology, where we are to able expand beyond the typical 30 to 60-year historical datasets and refine estimates of reliability with hundreds or thousands of years of data.


Drought planning and preparation requires a robust system of monitoring tools to ensure drought conditions are adequately tracked for a variety of water user groups. Lynker offers cutting edge technical solutions to develop and optimize drought mapping and analysis tools and our comprehensive approach aims to develop monitoring applications tailored to each user’s unique needs. Lynker applies open-source web-mapping software along with actively hosted web mapping service products to generate a seamless portal to help users navigate the abundance of drought-related data. This tool merges data analysis with actionable responses to promote timely and effective decision making.

Water Rights and Expert Witness Support

Lynker provides litigation support in a variety of water rights proceedings including historical consumptive use analysis, evaluation of surface water/groundwater interactions, groundwater modeling, conjunctive administration of surface water and groundwater rights, stream depletion analysis, development of protective terms and conditions, settlement negotiations, and expert testimony.

Municipal Water Supply Planning

Lynker has strong skills in developing and applying modeling tools for water supply planning on both short- and long-term scales. Our work often includes scenario analysis to study what ifs like how climate change may impact a region, or how feasible new water rights and reservoirs are given a set of existing constraints. A key component of Lynker’s work is the ability to communicate highly technical and often counter intuitive results to groups of non-technical stakeholders such as boards of trustees, farmers, or municipal planners.
