A project led by artist Ledia Carroll. She wrote:

“On Jan 20 2005 began mixing blue pigment into a white dolomite field chalk and applying it to a piece of the shore of the former lake with a baseball field line chalker. Through a grant I was able to complete drawing the line around the entire lake perimeter. On Oct 22, 2007 I completed a line around the former lake and hosted an alley cat bike race and bbq. Press release information about the events at the bottom of the page. Mission Lake Project was sponsored by SoEx Off-Site, a yearlong series of public art projects investigating diverse strategies for exploring and mapping public space, www.soex.org”
