Ire: Proposed Fialdorson Gravel Pit -Groundwater impacts
Dear Mrs. Wiesner:
As pcr your phone request, this memo is to provide our observazioas and conclusions
regarding the proposed Halderson Gravel Pit on Spring Creek Mesa. The alliance of
Spring Creek Homeowners had previously requested my evaluation regarding the
proposed gravel pit. The results of the investigation ware submitted is an opinion letter
dated June 20, 2003, for review and submittal to the Montrose County Planning
Commission. 1 also attended the fast Courrty Planning Commission meeting and provided
testimony regarding the application. This memo is for the Alliance's use az the next
County Commissioner meeting, where the gravel pit proposal will be considered for a
Special Use Pettnit.
Tfie fallowing are conclusions from our investigation:
i) The proposed pit wilt be a Large diameter well; intercepting groundwater.
2) Groundwater intercepted by the pit will be derived from three (3) sources: a)
natural precipitation on the property, b) natural underflow from snowmelt and
precipitation surrounding the property; and c) irrigation flows thmugh the gravel
beneath the mesa into the pit, from both irrigation water application and ditch
seepage.
3) Imerception of groundwater will require a welt permit, application for water rights
for the consumptive use of groundwater, and a plan for augmertation for
replacement of the groundwater.
4) Ahhough the pit will be a "groundwater well", waters cannot be "stored" in a well
for augmemation purposes.
5) intercepting the groundwater in this pit will have a direct impact (dry up) the
Nation's springs, (orated immediately adjacem to the northeast corner of the pit.
These springs are adjudicated as absolute water rights.
6) Excavation of this gravel pit, and consequently disposal of excess water, will
change the subsurface hydrology of this area of Spring Creek Moss. The impacts
will include change in agricultural irrigation water application practices, in that
the pit will Create a "sink", drawing water from alt sides and lowering the water
table. This increased groundwater gradient will drain surrounding lands faster
