Louisville Drinking Water

All of Louisville's water supplies are from surface water that are diverted from two watershed basins: South Boulder Creek and the Colorado River.

The Superior & Louisville areas drains mostly into Coal Creek which flows into the St Vrain River SE of Longmont.

So, not likely that the water we drink will be effected from runoff of the burned area of the Marshall Fire.
