The Water Resources Commission shall establish gauging stations at suitable points on the various streams of the state to determine the daily and seasonal fluctuations in the flow of the water; shall make surveys and profiles to determine the fall of stream suitable for power development; and shall prepare topographic maps of the territory adjacent to the private streams of the state, so that the availability of water for power, irrigation or other beneficial uses may be determined and made known to the public. All such maps and information shall be made a matter of record in the Water Resources Department and the commission shall publish a summary of all such information in the most practical and economical manner for presentation to the public. The commission shall enter into such agreements and contracts as will insure that the surveys and investigations are carried on in the most economical manner, and that the maps and data are made available to the use of the public as quickly as possible.
