- brown clumps may be either live brown algae or dead string algae if the lake was treated. Either way, this time of year it is normal to see more of that during spring turnover. If they still see that stuff at the end of June then worry. Spring turnover brings nutrients from the bottom and often causes a temporary algal bloom this will settle down as summer approaches. Here are a couple of articles covering that. https://www.rmbel.info/spring-turnover-in-our-lakes/ and https://www.canr.msu.edu/news/the_thermocline_a_summer_phenomenon_in_michigan_inland_lakes
