3. The Ecology of the Warm-Water Ponds in Utah. 



The project is designed to study the life history of the fish present in the small 

 natural warm water ponds, study of the limnology of these ponds, and to de- 

 termine what fish will reproduce naturally and produce a fishable population of 

 game fish.

1. Experimental Forests and Ranges (Watershed Improvement). 



The project aims to test effectiveness of several watershed improvennent measures 

 including: (1) Control of livestock grazing, (2) reseeding, and (3) contour trench- 

 ing for preventing the recurrence of violent mud rock floods during high intensity 

 summer rains. The study involves several watersheds and subwatersheds totalling 

 about 28,000 acres, some of which were intensively treated and others given only 

 protection from grazing. A network of recording rain gauges provides a record 

 for evaluating the depth-area-intensity relations of summer rains. Streamflow 

 records and observations of discharges are checked against the climatic record 

 and the treatment on specific subwatersheds. Since the improvement measures 

 were installed, channels have become more stable and streamflow more regular.

2. Study of Water Level of Fish Lake, Utah. 



Information is being secured to aid in the stabilizing of the water level of Fish Lake 

 to possibly aid in improving fish production and to determine the relation cf inflow 

 to total losses. This is a 4,200-acre extremely productive and popular trout lake.
