Watershed Consulting Associates, founded in 2005, has long recognized that to truly excel in the field of stormwater management, you have to specialize. Watershed Consulting was formed by a team of hydrologists specifically skilled in modeling, designing, permitting, and implementing innovative stormwater management systems to protect and preserve natural surface water resources. We offer services in green stormwater infrastructure design, watershed master planning, water quality investigation, river corridor management, and all aspects of stormwater permitting. We offer stand-alone services to our clients, work in close association with a select group of design, engineering, and planning associate professionals on multi-faceted stormwater management design projects. With our experience, partnerships, and knowledge of local stormwater best management practices and regulations, we are well-positioned to take on a range of projects from small and straightforward to large, complex investigations throughout Vermont, New England, and beyond.

Water Quality Specialist
Dana was born and bred on the coast of Maine and moved to Vermont in 2001 to attend Middlebury College where he earned a degree in Geography and Environmental Studies, focusing in GIS and cartography. After graduating, he worked with Middlebury’s GIS lab as a teaching assistant and later became an independent GIS consultant, working with a variety of public and private clients. After living in Colorado for four years, he returned to Vermont in 2011 to conduct his Master of Science research at UVM in Water Quality and Bioretention System Monitoring at the College of Agriculture and Life Science’s Plant and Soil Science Department.
Dana is currently a Water Quality Specialist for Watershed Consulting Associates, a position he has held since 2013. In his role with Watershed Consulting, Dana works with State and local governmental officials, non-profit organizations, and private industries on operational stormwater management design and permitting, bioretention system design and management, and water quality sampling and analysis, particularly in illicit discharge detection and elimination.
Dana’s specialties include the sampling and analysis of water from both point and non-point sources for nutrient pollution assessment and management, Geographic Information Systems database creation, analysis, and management for water quality and hydrologic modeling, pollutant modeling, Low-Impact Development design and water quality sampling, and stormwater permit preparation.
Dana is actively engaged in Vermont’s Green Infrastructure Roundtable, and is a Board Member of the Waterbury Area Trails Alliance, promoting sustainable, active recreation in Waterbury, where he lives with his wife, Louise, and a garage full of skis and bikes.
Kerrie has been the GIS Specialist at Watershed Consulting Associates since 2014. She holds a Master of Science in Natural Resources from the University of Vermont and a Bachelor of Science in Environmental Studies with a minor in Biology from Colby-Sawyer College.
Kerrie has focused on utilizing GIS technology to study real world water quality issues including quantifying stream erosion, mapping channel migration, and assessing connectivity of impervious surfaces. She has extensive experience working with ArcGIS software, developing models and managing large datasets. Kerrie worked as a digital mapping specialist for a commercial GPS company following undergraduate graduation. Upon entering graduate school, she worked as a Research Assistant focusing on mapping stream channel migration and assessing impact to water quality. After earning her master’s degree, she was employed at the University of Vermont as a Research Specialist where her work revolved around understanding how road-stream connectivity impacts water quality and mapping and assessing hydrologically connected impervious surfaces.
In additional to her computer-based skills, Kerrie also has experience with fluvial geomorphology, soil and stormwater sampling, and GPS mapping.
When she’s not thinking about mapping, you can find Kerrie riding her horse, hiking, or just enjoying life.
Molly Bruno was born and raised in central Vermont before moving to Burlington to attend college at the University of Vermont. She graduated from UVM’s Rubenstein School of Environment and Natural Resources with a Bachelor of Science degree in environmental science and a double minor in geology and geospatial technologies.
Molly began at WCA in 2013 as an intern, and since graduating has become a full-time team member. She specializes in field-based work operating at long and short-term scales. She has experience assessing water pollutants through collection and analysis of samples from rivers, streams, lakes, and stormwater infrastructure. Molly has knowledge gathering, recording, and managing data across multiple platforms. She also uses ArcGIS to perform data analysis and completes permit inspections for regulatory reporting. Molly’s background in geology helps her classify soil profiles and conduct infiltration testing in the field to better understand the hydraulic impacts of a site.
When Molly is not at work you will most likely find her exploring Burlington’s waterfront, swimming, attending concerts, or just relaxing with friends. She is an avid hiker and hopes to eventually hike her way through the New England Four Thousand Footers.
