Monitoring/sampling wells in Larimer County

3,225 of the 20,919 well permits in Larimer County — 15.4% — are decreed for monitoring/sampling.

How this group compares

Larimer County holds 3.5% of Colorado’s 91,022 monitoring/sampling permits, while holding 3.5% of the register overall — so it is over-represented in this use.

Monitoring/sampling means not a water supply at all — a hole drilled to watch the groundwater. These sit on the same register and are not wells anyone drinks from.

What happened to these permits

1,167 of the 3,225 permits decreed for monitoring/sampling in Larimer County ended with a well the Division was told about — 36.2%. And 983 expired without one: 30.5%.

An expired permit is the trap in a rural sale. A seller can produce a permit that lapsed years ago, and a permit is not a water right — the two are separate, and a purchase turns on both. What an expired permit does and does not mean.
