MAPPING OF INVASIVE MILFOIL IN SMITH AND SAYLES RESERVOIR
The Lake Management Committee, headed by Art Searle, has been mapping the invasive milfoil as they confront it in the lake. Click here to survey the mapping.
Three files in total have all been placed in the SDRA/Bathymetry folder.
According to NOAA,
“The term “bathymetry” originally referred to the ocean’s depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain. In the same way that topographic maps represent the three-dimensional features (or relief) of overland terrain, bathymetric maps illustrate the land that lies underwater. Variations in sea-floor relief may be depicted by color and contour lines called depth contours or isobaths. Bathymetry is the foundation of the science of hydrography, which measures the physical features of a water body. Hydrography includes not only bathymetry, but also the shape and features of the shoreline; the characteristics of tides, currents, and waves; and the physical and chemical properties of the water itself.”
ANNUAL DRAWDOWN REPORT
SDRA has an annual drawdown of the lake to help to deter variable milfoil and other invasives. Art S. has prepared an extensive view of the drawdown data for interested lake members and the public. To see this year’s lake drawdown report, please click here.

URI DATA BASE
Data from our water sample collection program is available on the URI website. For the Mmlti-year report, click this link. You can compare our results to other freshwater lakes in Rhode Island by clicking on the report for all lakes monitored by URI.
URI is gathering more detailed information about individual statistics for thing like alkalinity, dissolved nitrogen and phosphorous (both resulting from fertilizer runoff), and other information but has not yet to collate it all and post it online. Monitor that page for updates.
