In such cases it frequently happens that the heavy flow reaches the point of delivery in the middle of the night, while the light flow comes in the period of daylights Equalizing reservoirs on such streams would tend to increase effective use as much as 500$. Out on the West Desert there are numerous locations where small reservoirs may be built to retain the runoff from melting snows and from torrential floods in midsummer* Where the water retained does not need to be held back for stock watering and where it is not of sufficient volume to Justify irrigation development for agricultural crops it would he possible to install automatic systems of delivery into die tribution canals where uniform streams might be spread over the range land thus providing the moisture required for the production of grass and other cover* Ihis would tend to improve materially the range condition and provide oases where now there is nothing but ba* Ten deserto |
