City of Aurora Water Supply Planning

Lynker developed and assists in the maintenance of the Aurora, Colorado Raw Water Supply System Model which was built using the CRAM modeling framework hosted in Microsoft Excel. Staff at Lynker have been working with Aurora since 2003 on this model of their multi-basin water supply system. Ongoing tasks have included adding new CIP features, performing analysis of what-if scenarios and sizing of potential future facilities.

Lynker has added new reservoirs, treatment plants, and water-reuse/recovery facilities to the CRAM model, used for the recent Integrated Water Resources Master Plan created by Aurora Water. In addition, Lynker provides training and customization as requested for the modeling platform.

 

Idaho Ground Water Appropriators Conjunctive Use and Water Rights

Lynker, under contract with the Idaho Ground Water Appropriators, provides oversight of regional groundwater model development of the Eastern Snake Plain Aquifer. In addition, Lynker provides litigation support through technical memos and expert reports of groundwater modeling of aquifer management and mitigation plans, consumptive use analysis, analysis of historical water use data, and other water rights applications.

 

 

Boulder Creek and South Platte River Conjunctive Use and Water Rights

Under a retainer with the City of Boulder, Lynker provides expert water rights focused on assessing the quantity and timing of depletions to Boulder Creek and the South Platte River flows.

In support of the City, Lynker provides review and independent analysis for numerical modeling of conjunctive use and consumptive use analysis for technical memos and expert reports as litigation support. Work includes analysis of certain water court cases and State Engineer proceedings to which the City of Boulder is a party.

 

Jamestown and James Creek Master Plan

The Town of Jamestown Colorado was hit hard by a devastating mix of slope failures, debris flows, and flooding during September 2013, resulting in a fatality and damage to 20 percent of the town’s building stock, its roads, bridges and potable water system.

As a part of the recovery effort, Lynker developed a stream corridor master plan for the Town that serves as a road map for rebuilding the town, restoring the stream, and protecting against future events. The Lynker team conducted the science and engineering components of the project, including hydrologic and hydraulic modeling and development of a new (post-flood) Base Flood Elevation map for the town. They also performed public outreach to the residents, presenting technical and other information at public meetings and leading one-on-one meetings with the community aimed at understanding their needs and desires with regards to stream restoration and hazard mitigation, and explaining design concepts and alternatives. Lynker is currently leading the Natural Resources Conservation Service-funded Emergency Watershed Protection work in Jamestown aimed at protecting the town from further damage during spring-runoff.

 

 

National Weather Service Calibration

Lynker provided hydrologic, hydrometeorological, and reservoir model calibration support to the National Weather Service through the various River Forecast Center offices around the country. This ongoing task focuses on developing and optimizing watershed and reservoir models for more accurate streamflow and involves processing gridded and point-sourced hydrometeorological data for use in water balance analysis and model applications.

The primary component of the project is the calibration, evaluation and operational implementation of models for use in the NWS river, flood, and drought forecast practices. An essential element of the project involved configuring/designing the hydrologic workflows and visual displays within the Flood Early Warning System and Community Hydrologic Prediction System software structure.

 

Lower Poudre River Recovery and Resilience Master Plan

In response to the devastating flood of September 2013, the Coalition for the Poudre River Watershed hired Lynker to develop a flood recovery and resilience master plan for the Lower Poudre River.

The master planning effort combined scientific and engineering analysis with community collaboration to identify and prioritize opportunities to improve river resilience and river health. Components of the master plan included reach-by-reach analyses of changes to the historical channel, assessments of geomorphological and ecological values, identification of vulnerabilities, and sediment transport modeling. Lynker led a multi-faceted team of geomorphologists, ecologists, modelers and designers to create an informative, user-friendly master plan that provided recommendations through the project area.

The 36-mile-long project area showcases Lynker’s ability to develop river restoration projects through community outreach and adaptive priorities. The planning process included an extensive public outreach effort that drew on landowners and local community experiences to pinpoint vulnerable areas and important assets. Based on these meetings, a cultural aspect of the community was accounted for when developing restoration projects. Illustrative conceptual designs were developed for the high priority reaches while taking into consideration ongoing projects within the reaches. The master plan and sediment model developed for the Lower Poudre River are intended to be continuously evaluated during future planning actions or assessments to make reach-scale decisions that can help inform the solutions that may be best for a reach.

Lynker featured at American Geophysical Union (AGU) Meeting in Washington DC Dec 10-14 2018

Lynker team members attended the annual American Geophysical Union (AGU) Fall Meeting in Washington D.C. December 10-14. The Lynker team presented on several research projects including the poster below which summarizes recent work developing decision support tools for drought forecasting and monitoring.
