Otter Lake Shoreline Erosion Assessment & Mapping

Project Description


Northwater completed a detailed lake shoreline assessment, which included establishing a baseline inventory of shoreline erosion for the entire Otter Lake water supply reservoir (30 miles).  Northwater established a ranking system designed to quantify erosion and nutrient loading and to help prioritize reaches for stabilization. The assessment was accomplished through direct measurements, advanced geomatics equipment and GIS software.  Soil cores were obtained to determine the concentration of nutrients in eroded sediment.

A high-quality map atlas was produced to display results and help guide the Otter Lake Water Commission in making cost-effective and informed decisions related to in-lake improvements.  Northwater provides regular updates to shoreline maps, loading estimates, and priorities as lake banks are armored.

We have been working with Northwater Consulting on lake and public water supply improvement projects for almost ten years. Their assistance in obtaining and administering federal grant funds and providing project management and technical expertise for Best Management Practice Implementation has been extraordinary. Northwater also conducted high level GIS analysis for lake erosion assessments and additional mapping supporting many of our projects. Not only has Northwater delivered products on-time and with exceptional quality and value, their problem solving skills have kept our projects on time and within budget.
