<br />In hllllary 1998, The Conservation Fund (TeF) eOlwcycd to the eWCB 16.38 cfi; of the SnmvtYt""
<br />Divide Dih.-+: to help maintnin instE\-;am flov./s on Sw)'..vm~1ss Ct'eek (se.e ,:Uacl1cd Inap), The tenns of the

<br />agriculture (using other w()ter rtghi's),
<br />
<br />In Iv[iJlTh 2001, stafr retained Spronk \Vater Engineers ("Spronk)') to prepare an engineering analysis in
<br />suppo!"t oCthe ch~mge, Sp:'()nk":~ :::n:llysis had three key findings:
<br />
<br />1) The h:ggl~d return flo\vs hOlTl irrigation actually' t?~n~?r~t instreanl f10\VS held by the
<br />Board on both the Roaring Fork River and SnC\VlnaSS Cre,';J(. Spronk estilnated ihat
<br />the return flow 8.ccn:;::j [on to the R.J3ring Fork avcr3ges 958 acre-.feet per year.
<br />
<br />2) Stream nO\\' analyses indic:1tc that the instrcam flows for SnO\VnlaSS Creek \vere
<br />generaUy fully satisfie.d, 1--1"o\,I.1(;\'c1", it is believed that fJo;,vs in the tate Stnnlller and [;11I
<br />Gould drop bc]c:.\v the C\VCB instrean: f10\V k',,ic!s, particulady in dry years, There
<br />\vcre no now shortages identified for the Roaring Fork instrcall1 flow' fix the study
<br />j1cnod (1914-1918 and 1991-1998).
<br />
<br />3) (\dditiorwlly, st,lff a:-;d SIJrGllk disCCVCTCd that a change in use of the d0118k'J right

<br />respect to operation of Green ~vlountain Rescl"\/oir, End the ch~nged vV8tcr right could
