precipitation occurring during late spring and summer as afternoon thunderstorms, some of
which can be severe. The average annual temperature for the area is 53 degrees Fahrenheit (F)
with daily maximwn and minimwn recorded temperatures averaging from 73.0 F and 37.0 F
respectively. Daily summer temperatures easily reach highs near and above 100.0 F and winter
lows have reached into the minus 20.0 F range. The average frost-free season is 160 days.

There would be no effect on regional Dr local climate frDm any Dfthe alternatives.

3 .1.3 Water Resources

The Arkansas River, in modem times, has become a perennial river that has highly
fluctuating annual and seasonal flDws due to varying amounts of spring runoff derived from
winter snow-pack in the mountains, thunderstorms, and droughts. Today, the river is very highly
regulated for agricultural purposes and the John Martin Reservoir is a temporary storage facility
for the conservation of irrigation water. The Arkansas River drainage above John Martin Dam is
18,915 square miles.

The John Martin Project obtains potable water via a tank and pipeline system from nearby
water wells owned and operated by the Hasty Water Company located at the Hasty community.
The Corps connected to the Hasty Water Company system near the entrance to Project land. The
Corps constructed a delivery system and 20,000 gallon storage tank on Project land. The Hasty
wells prDvide gDod potable water and generally provide sufficient water for John Martin Project
use.

With no-actiDn, there would be nD effect Dr charige to the existing situation. CDloradD
State Parks' prDposal would provide engineering assistance and system upgrades for a service
line to the propDsed State Parks facilities. In the proPDSal, State Parks would prDvide a new
150,000-gallon tank, underground pipe, and prDvide fDr a new well. This would benefit the
cDmmunity by providing for an adequate supply Df water fDr IDcal demand. The Hasty Water
Company would provide the land necessary for the new well and tank, and for pipeline easement,
and would asswne the operatiDns and maintenance responsibility for the new facilities.

CDloradD State Parks' propDsal wDuld prDvide for some rehabilitation of the existing
Corps water line system in the Lake Hasty RecreatiDn Area and potable water would be supplied
to the proposed new visitor center, to 65 existing and to 35 new campsites in the Lake Hasty
Campground, along with the new campground buildings, to the State Parks maintenance
cDmpound, and at some future date (Phase II) to hydrants in the proposed new campground at the
Overlook Recreation Area. The three (3) Hasty Water Company wells currently do nDt have the
capacity to adequately supply the Hasty community, the Corps, and proposed State Parks' needs.
ColDrado State Parks has retained the engineering firm of Clyde B. Young for water development
feasibility and design work. In order to expand the Hasty water system as per Colorado State
Parks' proPDSal, Hasty Water Company members would have to apply for grant funding and/or
infrastructure loans that may not be readily available, and thereby, might be faced with higher
monthly water rates. Colorado State Parks is currently negotiating with the Hasty Water
