Lynker staff have supported the City of Boulder’s water supply planning efforts since the 1990’s with the implementation of CRAM to model their raw water supply system. Since 2003, the City of Boulder has incorporated climate change assessment into its water supply planning model, most recently in a NOAA-sponsored study initiated in 2006 and completed in 2008. Lynker staff completed model runs with climate-adjusted model forcings (climate adjusted natural flow and irrigation demands) to analyze system performance under future hydrologic conditions. In 2016 Lynker extended the CRAM modeling period of record to 2016 to include the 2012 drought conditions and updated the climate change analysis to include the Colorado River Water Availability Study Phase II climate adjustments to hydrology for the Boulder Creek watershed.
Success stories/projects we want to feature on the overall Success stories page.
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.
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.
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.
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.
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.
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 earned a NOAA’s Small Business Success Story of the Year in 2015. Lynker provides systems engineering, data management, GIS software development, and quality assurance support which has helped improve the accuracy, speed of processing, and distribution of critical nautical chart products to federal and commercial stakeholders. Our team built and supports NCSII (Nautical Charting System II), which is used by over 50 GIS Cartographers in OCS. The NCSII system maintains a vector nautical database which used to produce Electronic Navigational Charts (ENCs).
