Thank you for visiting this past week regarding the Platte Valley Pit (M-1989-120) located in
Section 30, T1N, R66W in Weld County just outside Brighton. The pit is operated by Aggregate
Industries.
The Groundwater Management Subdistrict of the Central Colorado Water Conservancy District
has operated a Wellfield at this location for augmentation of irrigation wells. We call this our
"Brighton Wellfield" and it contains a battery of six wells and pumps, approximately one mile of
cement-lined ditch, and electrical supply. About 15 years ago we were approached by the owner
of the property regarding gravel mining plans- We expressed concern over the effect of mining
on our wells, and entered into sporadic negotiations for approximately five years. In 1990, the
Weld County Commissioners approved the county mining permit with the contingency that the
mining company obtain an agreement with Central to protect our Brighton Wellfield. It took
another 10 years, but finally the Agreement was ratified in 2001.
We ran into trouble this spring as this was the first year the agreement was fully in effect. Water
was to be provided to Central on June 151, in the amount of 7 cfs offully-consumable water. We
did not receive this water from Aggregate Industries, and were forced to file a restraining order
against Aggregate on June 17`". A hearing was held in Weld County District Court on June 21st,
and Judge Hays ruled in Centrat's favor. (Ruling is attached.)
We have been working with Aggregate Industries to acquire the 7 cfs offully-consumable water,
but are currently only receiving 5 cfs. This shortage is being replaced with other augmentation
water supplies that we currently own, but could result in a shortfall of augmentation water later
this fall. This is a serious situation and could result in Central's 960+ member wells being shut
off by the State Engineer in the future.
