| huge blooms | 2010-06-10 | Lydd Petty Sewer Parallel to Megan Close, Lydd - the dyke runs along new built homes on one side and a farmer\'s field on the opposite site. Last year, the dyke had a profusion of rootless duckweed. This year, it\'s been overtaken by a new bloom of Gutweed or Ulva intestinalis Linnaeus. The dyke runs into the sea - water is brackish at best. |
