According to Colorado Parks and Wildlife (CPW) experts few years ago an individual has dropped few fishes in the lake and over the time offspring’s of the goldfish exploded in the region.
Experts claim that these goldfish are not native to the lake and they may pose great threat to the ecosystem and biodiversity of the lake.
Other species found in the lake are tiger muskies, catfish, bluegills.
Tiger muskies are also not native to the lake but they are controlling the population of suckers in the lake ecosystem there by maintaining harmony. Hence they are not posing any threat to the lake ecosystem like goldfish.
The spokeswomen for CPW, Jennifer Churchill said that there are two ways to get remove the fishes; either give electric shock to goldfish so that they come up to the surface and they will be collected and used as food for regional raptor rehabilitation center, or they will drain the lake.
The lake falls in the jurisdiction of Boulder’s Open Space and Mountain Parks department even though it falls outside the limits of Boulder city.
Canon asks peoples not to dump any fishes into the lake, this will harm the lake ecosystem and it is also illegal.
Another incident occurred in November 2012, where 2,275 koi goldfish exploded the Boulder’s Thunderbolt Lake; in this case also someone has dumped the fish in the lake three years ago.
