To answer your question Paulespo. Yes there is a control damn about 11 miles upstream from the springs. This damn allows people who live on the Lake Arrowhead shore to not worrie about flooding, much. There is a web site some where that will tell you about water levels on the lake. I belive you are smart enough to find it some how.. Thank for your report. It rained at my house all night and a little during the day yesterday. So expect the creek to rise. I live @ 20 miles from the springs.
Happy trails to you.
