<p>Lake Gehu is a severely <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">eutrophic lake</a> in southeast China. A series of restoration measures have been implemented since 2009 in northern <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">Lake Gehu</a>. This study compared aquatic plants, water quality, sediment, and <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">phytoplankton</a> between restoration and control areas to investigate the effect of restoration measures. The results demonstrated that aquatic <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">macrophyte coverage</a> increased from 0% to 10.6%; mean TP, TN, and CODMn concentrations increased by 50.0%, 42.4 %, and 40.8%, respectively, compared with those before the measures were carried out; the mean <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">Secchi depth</a> (SD) increased to 42.5cm, which is 1.4 times higher than that before restoration; the mean euphotic depth (Zeu) in the summer increased from 91 to 130cm; the mean chl.a concentration decreased from 34.8 to 20.2?g???L-1, compared with that before restoration; the Shannon???Wiener index of phytoplankton increased by 28.7%. The mean TP and TN concentrations in sediments decreased by 63.8% and 52.4%, respectively, compared with that before dredging. These results indicate that the restoration in northern Lake Gehu was effective. To complete the transformation from an algaeto a <a href="https://www.omicsonline.org/ecosystem-ecography.php" style="color:blue; text-decoration:underline">macrophyte</a>-stable state within the region, further measures must be adopted. This restoration of a eutrophic lake can serve as a reference for similar eutrophic lakes.</p>
