Bayshore At Agua Hedionda

I am disappointed with the Agua Hedionda Lagoon (Also known in the area as Carlsbad Lagoon) — Yes, Stinky Lagoon for those who speak Spanish — This is such a BAD name, I wish it would just get renamed to Carlsbad Lagoon, which is so much more dignified).
In a more recent visit to the Lagoon, I noticed that a NEW SIGN has been posted that says that:
SWIMMING is PROHIBITED
hmmmm. So how exactly are we supposed to enjoy this lagoon if swimming is no longer allowed?
However, buying permits for non motorized vessels is still allowed: Paddle boards, kayaks, etc.
So, If I flip off and fall of my kayak or paddle board? Am I not supposed to swim?
At the entrance of the lagoon, there was a tent with a City employee selling day/​yearly permits for using the lagoon with non motorized vessels (This includes paddle boards, surfboards, kayaks, etc. We were also reminded that dogs must stay on leash, that nobody can swim (kids or people not paddleboarding or kayaking can bake in the hot sand).
It is no longer allowed to use inflatable toys (We had brought some foam noodles for the kids to play with).
In short, the outing to the lagoon was a disappointment. We had 2 very hot kids that were complaining that they could not swim and the annoyance that we had hauled the noodles and other floating toys, but were told we could not use them anymore since swimming is not allowed.
Carlsbad has so many rules, it is just an unfriendly city for its residents. Some rules just don;t make sense to me such as: No dogs on city parks (This rule still is baffling to me, why is it that a dog cannot go into a park? Are they going to be banning kids next from going into parks?
I sure hope that the City gets more complains about such excessive rules, so they can make some changes. Just for an example, Encinitas parks ALLOW dogs and even ALCOHOL to be consumed in many of the Parks picnic areas.)
