|---|---|---|---|---|
| August 1996 | Lightning | Silverton | 4 hurt | no account filed |
| August 1999 | Flash Flood | Silverton | $10,000 | no account filed |
| July 2007 | Flash Flood | Silverton | $5,000 | Heavy convective rainfall concentrated just north of the La Plata and San Juan County line produced a massive flow of water, rock, and mud which traveled across the Durango to Silverton Narrow Gage Railroad track and dammed up the Animas River about one mile north of Needleton. Initially, the entire river channel was dammed. The river bed at that location was raised 8 feet on the east side of the channel and remained blocked on the west side of the channel. The debris flow covered about 250 feet of railroad track. The peak depth of debris on the railroad track was measured at close to 45 feet. The railroad track did not sustain significant damage, because the lowest several feet of debris on the track consisted primarily of mud. On top of the mud was a lot of rock material with some trees mixed in it. |
| August 1999 | Flash Flood | Silverton | $2,000 | no account filed |
| July 2021 | Debris Flow | Silverton | - | A debris flow occurred as a result of heavy rain over Ophir Pass in the Southwest San Juan Mountains. Social media footage showed a combination of rock and mud across the pass with cars having to turn around as a result of the debris flow. |
| July 1999 | Flash Flood | Silverton | - | no account filed |
