<br />the Upper reaches of the watershed where land treatment
<br />practices would have the most immediate impacts. This
<br />conclusion was reached after having completed an action
<br />plan in 1982 thai assigned work 10 the various agencies to

<br />forestry. wildlife. fisheries, and hydrologic data were
<br />gathered. complW and anolyzed, The federal land
<br />agencks. the Forest Service and the Bureau of Land
<br />Management. are accelerating their conservation treatment
<br />programs. Private and state lands thai can be quickly
<br />impacted by working in the upper range of the watershed
<br />are being assisted with 319 nonpoinl source funds as well
<br />as Colorado Stale Land Board funds, We are all working
<br />together to achieve common, and agreed to, environmental
<br />goals for the watershed,

<br />USDA AND EPA COOPERATE IN
<br />PRIVATE WELL PROTECTION PROJECT
<br />
<br />The U .S.Department of Agriculture and the Enviromnental
<br />Protection Agency will SOOn announce an inter-agency
<br />agreement to suppon a private rmal well protection project
<br />called Fann.A-Syst. The agreement will support an expansion
<br />of the Fannstead Assessment System. piloted initially in
<br />Minnesota and Wisconsin, for use nationally, The system,
<br />designed by the Wisconsin and MiIUlesota Cooperative
<br />Extension Services and EPA Region 5. provides a series of 12
<br />fact and work sheets to help fann owners assess how
<br />effectively their farmstead practices proteCt drinking water
<br />supplies, Fanners are given information on identifying.
<br />prioritizing, and reducing risks to their private wells,

<br />COLORADO WATER SUPPLY CONDITIONS UPDATE
<br />From the Office of the State Engineer
<br />
<br />Surface water supplies declined throughout the state during
<br />October, Except for the South Platte River basin which
<br />showed above nonna! supplies, the entire state showed below
<br />nonna! supplies, Generally, however, supplies have been
<br />adequate to meet demands, Statewide precipitation for the
<br />month of October was 83% of average ranging from a low of
<br />58% of avemge in the San Juan/Dolores/Animas basin to a
<br />high of 117% of average in the Colorado River basin. The
<br />statewide reservoir storage was 110% of avemge on November
<br />I, The San Juan/Doloresj Animas basin has the highest storage
<br />rate at 125% of average while the Rio Grande basin has the
<br />lowest storage mte at 88 % of average.
<br />
<br />The National Weather Service 30-day forecast (October 15
<br />through November 15) statewide is for above nonnal
<br />
<br />precipitation and below nonna! tempemtures, The 9O-day
<br />forecast (staning October I) is also for above nonna!
<br />precipitation and below nonnal tempemtures statewide,
<br />
<br />The Surface Water Supply Index (SWSl) developed by this
<br />office is used as an indicator of water supply conditions in the
<br />state, It is based on stream flow. reservoir stomge and
<br />precipitation for the summer period (May 1st through October
<br />31), Weight factors are applied to each of the measured
<br />hydrologic factors in computing the SWSI values for each
<br />basin, During the sununer period. streamflow is the primary
<br />component in each basin except the South Plane where
<br />reservoir storage is the primary component, The following
<br />SWSI values were computed for each of the seven basins on
<br />November I. 1991 and 1990:
