====Night Time Release Outlets====

Employs real time control on pond outlets to automatically close outlets during the day when surface outflow from ponds is warmer, and release water during the night when outflow temperatures are cooler.  The outlets are configured and programmed to maintain release rates below threshold values for stream erosion prevention and match pre-development peak flow rates.
