Dry Gulch Reservoir: Trout unlimited files Petition for Rehearing with Colorado Supreme Court saying storage safety margin reserve constitutes speculation

From the Pagosa Daily Post (Sheila Berger):

In its petition, Trout Unlimited requests the Supreme Court to remove from its November 2 opinion its endorsement of a one-year safety supply reserve, stating that, “the Districts would add a volume of water equivalent to a one-year’s demand to the amount of storage they would otherwise require, essentially doubling the size of the reservoir.” Trout Unlimited also alleges in its petition that planning for a one-year storage reserve constitutes speculation.

A one-year safety supply is, by definition, enough storage to supply one year of demand in the situation that a drought or another catastrophic event prevents PAWSD from diverting water from its stream sources. For example, in the summer and fall of 2002, even with sand bagging, a very minimal amount of river water was available for diversion. Because there had been no runoff in the spring of 2002, reservoirs were dangerously low. Even with severe drought restrictions, the District was very close to “running dry.” In 2002, the District had no storage safety margin. Currently, the safety margin is provided by the recently completed Stevens Reservoir Enlargement. For the first half of the 2002 drought year, sufficient river water was available for diversion. Reliance on storage became necessary in late June. The Trout Unlimited claim that a one-year safety supply doubles the size of the reservoir is an erroneous statement, as some of the first year demand would be served through river diversions and some of the storage reserve would be supplied by existing District reservoirs. Future drought patterns cannot be predicted with certainty, and the District has implemented its one-year safety supply margin to prudently plan for that uncertainty. The water districts feel that planning for severe drought is not speculative given the long historical record of, and recent occurrence of, severe droughts in the southwestern United States.

The response of the Supreme Court to the Petition is anticipated to be forthcoming in the next month. Meanwhile, the Districts will hold a special joint meeting at 6:00 p.m. November 30, at the PAWSD offices to discuss the case and the necessary next steps to preparing for another trial with the District 7 Water Court.
