This past weekend, Trail Life Troop 411 had the opportunity to go to the Aquarena Center in San Marcos, TX. The boys analysed water samples to find out how polluted the water might be by examining the bugs and larva they found in the samples. They also learned more about the local fish, underwater plants, and endangered species such as the blind salamander. On the glass-bottomed boat tour, they were able to see some of these fish and plants clearly under the water, as well as the low and high pressure springs that feed the lake.
