Frequently Asked Questions!

 Mammoth Lake Texas is a freshwater lake that is completely natural, with no added agents to improve clarity.  The visibility will vary depending on where you are in the lake, the depth, and the time of year you are diving.  Since visibility is subjective, we use the Secchi Disk to measure visibility during the year in accordance with the cycle of the lake. Even with aerators and added fish visibility is affected by weather (temperature, wind, rain, and sunlight). Lake visibility ranges from 5' to 45' throughout the year. 

Reservations are needed only if you require a RV spot or if you need tanks. If you just want to come dive out of your vehicle, no reservations are needed. We do recommend that you bring a canopy for shade! Please email us at info@mammothlaketexas.com or call (979) 288-6118

We accept cash and credit/debit cards.

Park fees are listed under the fee tab.

We require Observers to pay an entry fee at Mammoth Lake Texas, because we are not a public lake, and it is not subsidized as such.  We are classified as a recreational/amusement facility, and all of our grounds and lake maintenance/insurance/staffing, etc is funded by park admissions.  Again, we are first and foremost a scuba diving facility, but the governing bodies that regulate us do not differentiate between guests who scuba dive and guests who do not scuba dive.  

Air fills are available for $10 for non members and $5 for members. Fill cards are available online and at the gate. Phil station is open till 4pm on days we are open. Current VIP and Hydro is required!!!

Rental gear is available (Tanks). Please reserve by emailing us at info@mammothlaketexas.com or calling (979) 288-6118.

As a courtesy Mammoth Lake Texas does not charge Instructors or Dive Masters who are actively teaching a class at the lake. Please do not abuse this privilege as entry fees keep the lake open.
