She is a member of veteran coach Punch Tremaine's training squad that has historically been given one lane to use for training purposes at the pool.
In a letter to the Otago Daily Times, Ruske said she was not able to train at Moana Pool now her coach is in hospital.
While Tremaine (79) is out of action, the 14 members of his squad have been accepted into John Cornfoot's training squad.
But they are not able to use Tremaine's lane at Moana Pool.
Dunedin City Council aquatics manager Steve Prescott told the ODT the council has contractual arrangements with other coaches and could not allow Cornfoot to use the lane without giving other coaches an equal chance to bid for the space.
"We have to be careful that we don't have too many coaches in the pool at any one time," Prescott said.
He is mindful that the public also has to be catered for within the limited pool space.
"We have to to make sure that everyone - the swimming squads, the public, and other water sports - get a fair share of pool space," Prescott said.
Cornfoot has been coaching masters swimmers and triathletes at the Taieri College pool.
Ruske complained the temperatures and hygiene at that pool had got worse over the last few weeks.
"The filter has not been working and the pool has not been heated," Ruske said. "I found it so cold the other morning that it was almost impossible to swim. It could have been warmer swimming at Lake Waihola."
Ruske claimed the condition of the Mosgiel pool could lead to injuries or sickness.
"It would be untimely if it happened before an important swim meet," she said.
Because of the deteriorating conditions at the Mosgiel pool, Cornfoot asked the council if he could use the Port Chalmers pool. Prescott agreed to this request.
"It is heated and filtered," Ruske said. "But it does not have blocks which are very important as I am trying to quicken my reaction time off the blocks. Diving off a slippery bit of concrete is not ideal."
Ruske also complained about the commuting time from her home to the Port Chalmers pool. It takes her 25 minutes to drive to Port Chalmers.
"The pool isn't appropriate for training and isn't nearly as nice as Moana Pool," Ruske said. "We need access to Moana Pool for training with or without Punch Tremaine."
Prescott said the lane would be kept for Tremaine when he recovers from his illness.
"If Punch's health does not permit him to continue we would have to allow all the other coaches in Dunedin to bid for the space," he said. "We also have surf swimmers, water polo and underwater hockey guys who would like to have that lane."
Prescott also has to weigh up the demands of the public who are also demanding more lane space.
"As much as I understand Aleisha's predicament I have to meet all the community's needs," he said. "We struggle because of the limited amount of water space we have.
"I can't make an exception for Aleisha because if I make it for one person I have to make it for everybody.
"We try to cater for as many people's needs as we can but I'm caught between a rock and a hard place. I have to be fair and equitable and I think we do that pretty well."
