Project Overview

Executive Summary

In an attempt to better understand the state of overgrowth in aquatic plant life within Indian Lake, these surveys were done in affiliation with the ILWA. Previous surveys have been done within the same topic however none have been taken by any corporation with the goal in mind of processing future collections to organize a timeline of data. In order to get a thorough analysis, the 2013 survey was conducted in a way to set protocols for future teams to take more collections and compare data to organize solid empirical evidence to judge whether the lake must be treated, managed differently or left untouched. The 2015 survey followed their methods while adding Little Indian to the survey, and beginning the stenciling of storm drains.

Research into Indian Lake through previous surveys revealed that the lake is known as a eutrophic lake. This means that pollution, littering or a possibility of other events has led to the buildup of excess nutrients in the lake for plants to feed on causing this overgrowth.

For both surveys, data was collected from a set number of points and catalogued in a spreadsheet. The spreadsheet was then programmed into a file capable of integrating with the Google Earth program to provide visualization of the problem at hand. These maps depict every variable of data at each collection point. Multiple maps of varying data collections were created in a way that could be laid over top of one another to determine any potential correlations between two or more conditions. Results from the second survey were compiled onto their own maps, as well as a combined map containing data from both surveys.

A Revit model was developed for the 2015 survey. Revit is a four dimensional program used in hope to aid potential future professional organizations aiming to treat the eutrophic lakes. The Revit model shows the contour maps of Indain Lake and the surrounding area. Additionally, a tracking system of the storm drains through Google maps leading to Indian Lake was created for the ILWA using past information and stenciling done by the group.

This websites purpose and design allows easy access for common citizens with a vested interest to attain information about the situation as well as contact those in charge to report areas of overgrowth or other concerns on the lake. It will also be used in future projects to notify the public of the progress of each project during the collection process.

2013 Project Goals

  • First identify what the aquatic vegetation is present in Indian Lake.
  • Assess how growth density effects recreational use of the lake and biological conditions.
  • Form recommendations regarding plant management as well as prepare for future surveys projects.
  • Inform the lake community through this website.
  • 2016 Project Goals

  • Identify the aquatic vegetation present in Indian Lake.
  • Assess the change of vegetation in the lake from 2013 to 2015.
  • Create a tracking system for the ILWA regarding the stenciling of storm drains .
  • Develope a Revit design of Indian Lake for use by contractors in the future.
  • Update the ILWA website to reflect new findings and proposed ideas.

  • Developed as Part of a WPI Sponsored Project
    In Affiliation with The Indian Lake Watershed Association
    Worcester, MA 2013 & 2015
