Up to 100,000 fish die at Sparks Marina

Nearly every fish at the Sparks Marina Park has mysteriously died. Wildlife experts are searching for what has caused this major fish kill, which has claimed as many as 100,000 fish.

It all began last month, when about 3,000 trout, bass, and catfish washed ashore at the marina. Then wildlife officials kept hearing anecdotally that more fish were dying. So on Monday, they decided to take a boat out with an oxygen sensor and fish-finding sonar.

"Much to our surprise and chagrin, we ended up having a lake where we found literally almost zero fish in it and we still found some very low dissolved oxygen levels."

That's Nevada Department of Wildlife Spokesman Chris Healy. He says they don't yet know what's causing such a drastic decline in oxygen and why those depleted oxygen levels are persisting for so long in the 77-acre lake.

"We'll have to get the answers first and then we can start the work of rebuilding the fishery. It's just a little disheartening that we lost this fishery because it certainly was a popular one with local anglers.

Once officials can restore oxygen levels in the lake, rebuilding the fish population will take about 3-5 years. In the meantime, Healy says no major fish clean up is required because most of the dead fish sank to the bottom of the lake and are decomposing.
