The Family Biotic Index score of 5.2 at the Locke Lake <br />`Above' site and the Family Biotic Index score of 5.6 at the Locke Lake `Below' site <br />indicates a stream health score of "Fair ". <br />The Locke Lake `Park' site, which was a new monitoring location in 2012, showed a <br />stream health score of 4.7, indicating a stream health score "Fair ". <br />Further long -term sampling data is required in order to more accurately gauge the overall <br />rate of stream health change at these sites. <br />• <br />• <br />• <br />
