Armed with his trapping gear and wearing hip waders, he headed out toward the snapper. But he never got there.<\/p>\n<p>A few yards from shore, he could move no more. &#8220;I was up to my thighs in muck.&#8221; He struggled for a bit, then scanned the shoreline for help. &#8220;No one was around,&#8221; he recalls. &#8220;Not a soul.&#8221;<\/p>\n<p>But then a truck stopped, and a man stepped out. &#8220;You&#8217;re stuck, aren&#8217;t you?&#8221; he asked. Yup, replied Williams. &#8220;Well, I can help you,&#8221; the man said.<\/p>\n<blockquote><p>&#8220;I would&#8217;ve come out naked.&#8221;<\/p><\/blockquote>\n<p>Could he ever. The Good Samaritan was also one of the heavy-machine operators. He mounted his idle excavator \u2014 a &#8220;monstrously big thing,&#8221; recalls Williams \u2014 and fired it up. All the while, Williams was thinking, &#8220;How is this going to work?&#8221;<\/p>\n<p>The operator expertly maneuvered his rig so it perched on the very edge of the pond, and extending the bucket to its full reach, just to where Williams could grab it.<\/p>\n<p>The huge bucket soon loomed directly and, from Williams&#8217; stuck perspective, menacingly over his head. &#8220;All I can think is that if his rig toppled into the pond, I&#8217;m going to be driven 10 feet into the sediment.&#8221;<\/p>\n<hr \/>\n<h5>In 1998, the beloved Puddle&#8217;s massive makeover began with its complete draining.<\/h5>\n<div class=\"intrinsic-container intrinsic-container-4x3\"><iframe loading=\"lazy\" class=\"juxtapose\" src=\"https:\/\/cdn.knightlab.com\/libs\/juxtapose\/latest\/embed\/index.html?uid=515585a8-8a72-11e6-aace-0edaf8f81e27\" width=\"300\" height=\"150\"><\/iframe><\/div>\n<p>The operator had a plan. &#8220;I don&#8217;t think I can just yank you out,&#8221; he called to Williams, who heartily agreed with the anti-yank sentiment\u00a0\u2014 &#8220;I would&#8217;ve come out naked.&#8221;<\/p>\n<p>Instead, the idea was for Williams to grab the teeth of the bucket, and then the operator would rock him back and forth to break the suction.\u00a0 &#8220;It worked,&#8221; says Williams. &#8220;He was able to lift me out, swing me around, and deposit me on the shore.&#8221;<\/p>\n<p>With the pond bed eventually scraped clean, workers covered it with six inches of clean, coarse sand.<\/p>\n<p>Lake Andrews got its name in the 1910s when Delbert Andrews, Class of 1910, helped students create a skating rink by damming a swampy area of campus behind Hathorn Hall and Parker Hall. In 1958, as Bates embarked on a building program, the college excavated wetland to create a formal retention pond to handle stormwater runoff.<\/p>\n<div id=\"attachment_117129\" style=\"width: 1929px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-117129\" class=\"size-full wp-image-117129\" src=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1.jpg\" alt=\"\" width=\"1919\" height=\"1177\" srcset=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1.jpg 1919w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1-400x245.jpg 400w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1-900x552.jpg 900w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews1-200x123.jpg 200w\" sizes=\"(max-width: 1919px) 100vw, 1919px\" \/><\/a><p id=\"caption-attachment-117129\" class=\"wp-caption-text\">During the 1998 restoration, Lake Andrews was drained by opening the sluice gate at the north end.

(Marc Glass &#8217;88\/Bates College)<\/p><\/div>\n<p>Like many urban ponds, Lake Andrews gets\u00a0much of its\u00a0water from stormwater running off roofs, parking lots, and lawns, so it has a harder time staying healthy than its country cousins.<\/p>\n<p>&#8220;The water doesn&#8217;t receive filtration that a natural pond would from forests, land, and soil,&#8221; says Williams, the longtime director of<strong>\u00a0<\/strong><a href=\"https:\/\/www.lakestewardsofmaine.org\/about\/\">Lake Stewards of Maine<\/a>, a nonprofit that works to protect the health of Maine lakes by collecting citizen-reported scientific information.<\/p>\n<p>In the years prior to the 1998 restoration, Lake Andrews was susceptible to <span data-dobid=\"hdw\">eutrophication, which occurs when a body of water receives too many nutrients, especially nitrogen and phosphorus, prompting overgrowth of plants and algae. <\/span>Even in Williams&#8217; era, the Puddle had a bad rap. &#8220;No one would stick their pinky in it.&#8221;<\/p>\n<p>The marine clay layer that exists all around the Bates campus doesn&#8217;t help the pond, explains Williams. &#8220;Marine clay tends to be impervious; it doesn&#8217;t absorb water. So the watershed runoff, rather than filtering into the ground, tends to erode the clay, creating silt that carries nutrients like phosphorous into the pond.&#8221; (Years of silt runoff also created the deep muck.)<\/p>\n<div id=\"attachment_117132\" style=\"width: 1929px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-117132\" class=\"wp-image-117132 size-full\" src=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4.jpg\" alt=\"\" width=\"1919\" height=\"1357\" srcset=\"https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4.jpg 1919w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4-400x283.jpg 400w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4-900x636.jpg 900w, https:\/\/www.bates.edu\/news\/files\/2018\/07\/lake-andrews4-200x141.jpg 200w\" sizes=\"(max-width: 1919px) 100vw, 1919px\" \/><\/a><p id=\"caption-attachment-117132\" class=\"wp-caption-text\">At this site, between the Museum of Art and the pond, the college created the new Florence Keigwin Amphitheater. (Marc Glass &#8217;88\/Bates College)<\/p><\/div>\n<p>Planted along the shore, aquatic and terrestrial buffer vegetation, including lots of bulrush and low-bush blueberry plants near the Museum of Art, help to filter sediments and nutrients from watershed runoff. Some 250 tons of rip-rap (large stones that prevent water erosion) were placed in some areas, vertical stone walls built in others, to further stabilize the shore and curtail silting.<\/p>\n<p>The restoration also entailed a passive runoff filtration system to capture nutrients. \u201cIt was fairly sophisticated technology,\u201d says Williams. &#8220;The goal was to slow down the pond&#8217;s return to a eutrophic state, though it will never be completely turned around due to it being an urban pond.&#8221;<\/p>\n<p>The existing path around the pond was moved back from the shoreline, improved, and named the Marjorie Burgoyne Walkway. With granite from an old quarry in Lincolnville, Maine, the college built the new Florence Keigwin Amphitheater to help connect the Museum of Art to the pond.<\/p>\n<p>Much of the 1998 Lake Andrews shoreline restoration was funded through a $1-million gift from Jack Keigwin &#8217;59 and his wife, Beverly, longtime supporters of projects that improve and enhance the Bates campus. The naming of the amphitheater honors Jack&#8217;s aunt, while the path honors Beverly&#8217;s mother.<\/p>\n<p>&#8220;The Lake Andrews area has a significant potential as a place of respite and rejuvenation,&#8221; Jack Keigwin accurately predicted at the time. &#8220;It is a place to gather and to celebrate, a place for recreation for the soul and mind.&#8221;<em><strong>\u00a0<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Twenty years ago this summer, Bates began a major restoration of the Lake Andrews area.
