Chair Lanyon answered that initially there could be an increase in the population, but ultimately they would die. Grundhofer expressed concern that the temperature change as a result of the runoff could cause problems for the frog and dragonfly eggs. Asleson stated that it would be difficult to measure, but the shading in the parking lot would help cool the runoff. Grochala suggested that it might bounce in the outlet. Asleson answered that the effects were unknown. Chair Lanyon stated that it would be worth it to monitor the outflow temperatures. Grochala concurred that a case study could be done. Asleson stated he took surface temperature readings on two occasions at George Watch Lake and Marshan Lake. He found that the water temperatures did not fluctuate much in George Watch Lake because the lake was so shallow it would never stratify. Chair Lanyon concurred adding that freshwater systems were adapted to mdden changes.
