Construction of Cochiti Dam may have altered flood dynamics on the Rio Grande. Therefore, it may be more reasonable to evaluate the recurrence interval of the flood you identified in question 3, by only considering the flood record from 1974 to 1999

Recalculate the recurrence interval of the flood you identified in question 3, using only this shorter record. Show your calculations.
