access boat ramps are available free of charge. The private boat ramps at the marinas or in some of the parks are available to the public for a fee. There is no fishing or swimming allowed at any of the boat ramps. Lake level concerns Plans by GBRA to sell water from Canyon Lake to supply the fast-growing San Antonio and Austin regions have raised concerns that the lake will fall well below the established conservation pool level, potentially causing problems ranging from erosion and weakening of Canyon Dam to a decline in property values and possible health issues from the exposure of long-submerged land. This has led to several administrative actions and lawsuits over the future of Canyon Lake.
