Twenty.four chemical and/or physical <br />water quality parameters were analyzed. These <br />analyses revealed that watcrs of both lakes were <br />high in dissolved OXVL!:cn, slightly acidic, and low <br />mineral conh:nt. These findings were found to be <br />typical of good Florida lake water. <br /> <br />" <br /> <br />Wave Action <br /> <br />(personal observations) <br /> <br />Boat produces average of 3 waves per pass, <br />- typical set 01"24 passes = to tal 72 waves <br />Nature produces; <br />- Avemg:edailywindspeed IOmph <br />.
