I was one of 5 staff divers (4/water...1/boat...and a non-diver shore tender) from our shop conducting a SAR last evening for a client to locate and recover a boat engine lower half at Mountain Creek Lake. I have never dove this lake and now understand why. The lake on average is 5-6ft. deep muddy/silty bottom creating a zero vis dive enviroment......no plant life and I saw or should I say felt any fish. Water was HOT at the surface. Lots of the usual junk on the bottom. Some mod. current as a result of the outflow waters from the TXU power plant which also accounts for the high water temp.. The sign at the boat dock WARNS fishers NOT to consume the fish as they are contaminated from various chemicals present in the waters. We have not yet located the engine. This lake will not make the top 10 best Tx. dive lakes---lol
