EVERYONE who enters the park needs a waiver on file, even if they aren't diving. You can sign this year's waiver here: Sign Waiver.

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 35' throughout the year.

We are a dedicated scuba diving facility. We do not allow entry solely for the sake of swimming. If you are with family members who are scuba diving, then you are here for scuba related purposes and swimming is permitted in that case. If you are looking for just a place to swim or camp and are not a diver, then one of the area public lakes is a better fit.

You may only scuba dive if you have certification as an Open Water Diver OR are accompanied by a credentialed instructor. Swimming is permitted if accompanying a certified diver, however, please be aware of scuba instruction that may be going on around you, so as not to impede the learning experience and safety of new divers.

Steer clear of areas around diver down flags, as well as areas where you see bubbles rising. As stated above, if you are looking for a nice day at the lake and you are NOT a scuba diver or WITH a scuba diver, then another area public lake would be a better fit for you.

You are welcome to bring your own picnic, or provisions to cookout, but NO GLASS PLEASE. Being the home Buccees, there are several within a mile of Mammoth Lake Texas. Also, we have several restaurants in the area as well.

Mammoth Lake Texas is a 65-acre dedicated scuba park that was a sand pit and was filled in by a naturally occurring aquifer. The lake is not chemically treated, and we have a variety of aquatic wildlife as well as underwater attractions for you to visit during your dive!

NO, we do not allow the use of kayaks or paddleboards any longer. Again, The Scuba Ranch is first and foremost a scuba diving facility. Our regulatory agencies are very particular about the use of these vessels and we no longer have them available for rental. If your primary objective is kayaking and you have your own kayak, a public lake/river is a better fit.

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.

See answer to above question. EVERYONE that enters the park MUST have a liability waiver on file! This includes parents/guardians, infants, children, etc. A parent/guardian must fill out a waiver on behalf of a minor.

NO!

LEASHED dogs are welcome at the park. However, we do have the following boundaries:

• No dogs in the lake – period, even if the dog can swim.
• Please bring a crate/tie-out to safely contain your dog while you are diving (do NOT leave them in your car unless you are willing to leave the air conditioner running while in the lake).
• Please bring bags to clean up after them. We have lots of people walking around bare-footed or in their flip-flops or scuba booties…stepping in your dog’s poop makes your dog’s presence less enjoyable for everyone.
• Service dogs are of course welcome, subject to the above guidelines as well.

Discount options may be available for groups of 12 or more. Call or email for quotes: (979) 288-6118 or dive@divemammoth.com.
