Try for a TB/TM Project

• Basin of Origin: fight to protect a way of life• Basin of Use: fight to meet a pressing demand• Projects become EIS and permitting fights if there is any federal nexus

• Projects are Water Rights fights– The court for appropriation is in the basin of origin – The court for a change of use is in basin of use– Newer requirement to notify in both basins (court ruling).

• Notice the word Fight here?

Recent TB/TM Proposals

• Big straw• Flaming gorge pipeline• Yampa pipeline• Union Park Reservoir• Moffat firming project• Windy gap firming project

Silver Lining in TB/TM Waters

• Right to reuse imported water 37‐82‐106 CRS• Thornton v. Bijou (right to reuse)• Dominion and control of the reuse water

– Never lose the interest in that reuse water even after a long time of non use.

• Those who became dependent on reuse water? – Intensive accounting yields water you thought you’d lost.

– Exchange, exchange, exchange…

Silver Lining –some tarnish

• Today a lot of reuse water leased for replacement of agricultural well depletions

• New Reuse projects (municipal) coming…what happens to that agricultural demand?

• There isn’t enough TB/TM to fulfill all needs• Are we hitting the limits on exchange potential

• When does water quality become overwhelming?

Where Are We Today?

• Fierce posturing about new TB/TM diversions• Negotiations (CRCA)• Additional Agricultural Dryup on east slope still needed– Alternatives concept (fallowing) a hot item

• Reuse of available TB/TM (shuffling the deck?)– Prairie waters project (poster child)– ??
