commercial vegetables, potatoes, and home gardens. 



c. Declines in acreages of hayland, open pasture, and brush pasture. Pro- 

 jection of a greater decline in hayland than in pasture, and a continued 

 tendency to use pasture relatively more for young stock and dry cows 

 than for milk cows. 



A comparison of the pre- and post-construction "optimum" levels of 

 management shows that crop yields and carrying capacity of pasture would, 

 in general, be higher in the post-construction period.

Despite assuming full use of owned and leased lands in the pre- and post- 

 construction periods, respectively, and higher management levels, the de- 

 cline of 50 to 70 percent in acreages used for agriculture under the "opti- 

 mum" comparisons was sufficient to still affect substantial drops in output. 



Generally, however, post-construction outputs under "optimum" assump- 

 tions were higher relative to pre-construction outputs than was the case 

 under "actual" assumptions. This is indicative, for most of the areas, that 

 the "actual" post-construction level of management was low relative to 

 current technology. In fact, in some instances, per acre yields were actually 

 lower than in the pre-construction period.
