3. Hydroelectric Impacts
The timing of the flows at Navajo Dam is expected to be affected by the flow needs of
endangered fishes. The result will be reduced power to the city of Farmington and the
surrounding area. Although the reduced power is included as an impact in this analysis, the city
has no property rights to water flows through Navajo Dam, and thus the reported impact
represents an upper bound on impacts due to protecting fishes (USDOI, 1986).21 The dollar value
of the losses in power production are reported in Table 5-D-3. The data reported in this table
represent the direct impacts that were introduced into the regional I-O model to compute the
economic impacts associated with the actions taken on behalf of the endangered fishes.
4. Recreation Impacts
The dollar value of losses in recreational activity due to fish protection measures is reported in
Table 5-D-3. The recreation impact is incurred in each year of the study period from 2010
forward. The exclusion of potential gains in recreational activity due to increased river flow is
not included in this analysis; thus, the impacts reported represent an upper bound on the impacts
due to critical habitat designation.
The model was projected for the years shown in Table 5-D-3. The direct impacts occurred
throughout the study period. To introduce these impacts into the model the impacts for each
model year were derived from the data presented above. For example, impacts associated with
foregone agricultural production from NIIP Block 10 were projected to occur over the period
2000 through 2004. The model years are 2000 and 2005. Thus the NIIP related impacts were
prorated and the resulting direct impacts entered in 2000 and in 2005. These impacts appear in
Table 5-D-3 as direct supply reductions for the agricultural sectors. Similar procedures were
followed for the remaining agricultural impacts.
21 The agreement between the City of Farmington and Bureau of Reclamation states the following: "The United
States shall not be liable for any power losses, real or otherwise from its operation of the Dam and Project." (p.18) and
continues: "The implementation of this agreement does not in any way restrict Reclamation from making any future
modifications or improvements to the Dam or Project."( p.20).
