Temporal variations in physicochemical parameters of Bailuwan Lake: Twater (A,B), pH (C,D), FNU (E,F), EC (G,H), DO (I,J), and TOC (K,L). Left panels (A,C,E,G,I,K): red lines indicate mean values per sampling time (n = 12); and right panels (B,D,F,H,J,L): black dots denote monthly means (n = 4) with whiskers representing mean ± SDs. Additional details are provided in Fig. 3.
