gutters drain into the waterways. On rainy days, the gutters of the parks that are still connected to the Rivers of America allow for the river to rise to its normal level. Over-topping of concrete embankments happens frequently but has never posed a major issue. Originally, the Rivers of America required draining every 5 years in order to clean up sunken debris, scrub algae forests away, and maintain upkeep of the Mark Twain and Columbia Sailing ship guidance track. In January 2010 when the river was drained after 7 years of continual operation, items found in the river were numbered in hundreds of cellphones, pagers, walkie talkies, a computer tower, a prosthetic leg and half of a Davy Crockett Explorer canoe. To prevent the Jungle Cruise and other waters from draining as well, the underground tubes were plugged with air bladders. Any fish and wildlife found in the river were placed (alive) back into the remaining waters of the park. Any Koi fish found, were donated along with the Koi once kept at the Disneyland Hotel, to the Huntington Library. When the Rivers of America were refilled, the wildlife migrated back into the river. With its most recent refurbishment and the addition of a specialized pumping and cleaning system that would not disrupt the aquatic life, the Rivers of America would not need to be drained for another 20 years.
