Interim report on the progress of an inventory of artesian wells in Florida: leading to the enforcement of sections 370.051 - 370.54, Florida statues

One of the causes of lower artesian pressure, water waste and aquifer contamination is the misuse and insufficient care of artesian wells. In 1953, Senate Bill No. 57, entitled "An Act to Protect and Control the Artesian Waters of the State" (see Appendix) became a law. This law was passed through the efforts exerted by leading members of the Senate and the House of Representatives, who understood the need for a wise and controlled expenditure of our most valuable natural resource. The State Geologist and his authorized representatives were designated by this law to enforce this conservation measure; however, no financial provision was included for the 1953-55 biennium. The proposed program of the Florida Geological Survey for this biennium did not include the funds nor provide any full-time personnel for the enforcement of this statute. As a result, little actual work was accomplished during these two years, although much time was given to planning and discussion of the problem. Realizing that this program could provide additional basic data needed in the analysis of the water-supply problem, the State Geologist sought and was granted by the 1955 Legislature adequate funds with which to activate the first phase of the enforcement of Florida Statute No. 370.051-054. Enumerated below is a summary of the progress made on this investigation as outlined previously: 1. Data have been collected on 967 wildly flowing wells in 22 counties. 2. Chloride determinations have been run on 850 of the 967 wells. 3. Of the 967 wells, 554 have chlorides in excess of the 250 ppm, the upper limit assigned by the State Board of Health for public consumption. 4. Water escapes at the rate of 37, 762 gallons per minute from these 967 wells. This amounts to 54, 377, 280 gallons per day. The investigation is incomplete at this time; therefore, no final conclusions can be reached. However, from data already collected, the following recommendations are proposed: 1. That the present inventory of wildly flowing wells be completed for the entire State. 2. That the current inventory of wildly flowing wells be expanded at the conclusion of the present inventory to include all flowing wells. 3. That a complete statewide inventory program be established and conducted in cooperation with the Ground Water Branchof the U.S. Geological Survey. 4. That the enforcement functions as set down in Sections 370.051/.054, Florida Statutes, be separated from the program to collect water-resource data and that these functions be given to the Water Resources Department, if such is created (to be recommended by the Water Resources Study Commission in a water policy law presented to the 1957 Legislature). 5. That the research phase (well inventory) of the program remain under the direction of the Florida Geological Survey. (PDF contains 204 pages.)

Final report on an inventory of flowing artesian wells in Florida: leading to the enforcement of sections 373.021 - 373.061 Florida Statutes 1957

This report published as Information Circular No. 21, together with the interim report published in 1957 as Information Circular No. 10, Florida Geological Survey, illustrates as completely as possible the situation that now exists among the freely flowing wells of the State.

Observaciones sobre las especies de truchas criollas.

The genus Percichthys (Serranidae) includes three nominal species in Argentina, trucha, vinciguerrae and altispinis. The authors of this paper examine materials from: 1: the Río Negro river in its inferior course, in front of Viedma; 2: lake Pellegrini, near Neuquén, where the rivers Neuquén and Limay meet and form the Negro; 3: Plottier, near the place just named; 4: Colorado river, in Fortín Uno; 5: Curacó river, a tributary to the Colorado, now cut into separate sections since years ago on account of the lack of water; this river normally would connect the Colorado with the rivers up to the San Juan where the « trucha » lives; 6: Luro or La Salada lagoon, formed by the Colorado river near its mouth; 7: Argentino lake, in the southern Patagonia. These fishes are known as « trucha criolla » or « native trout » although the old Spanish name was « perca », more appropiate. Percichthys altispinis Regan 1905 is a good species ; it has been re-found in the Colorado river, at Fortín Uno. An illustration of it is given, characters of four specimens and a note on its scales. P. trucha C. V. reveeals itself on close examination as a complex species or linnean species (linneon) ; with several combinations of characters, but even more materials are needed to establish if there are geographical races (subspecies). A new examination of the Chilean materials is required (former authors considered them jointly with the Atlantic versant or Argentine materials). Some of the infraspeciíic forms are prognathous, and low finned ; others, the contrary; the head may be normal, or conical and bony; etc. As to P. vinciguerrae its standing as a valid species is doubtfull; perhaps, with P. laevis Jenyns it is a southern form. In the same reduced habitat (lagoon, or isolated course) diversified forms are present; some show parallelism with those of other places ; it is supposed that they show ecological influences according to the year or season of birth or developpment. A thorough study of the scales is given, with epidological characteristics and general conciusions as to the method of measuring and comparing their « reading». There are some marked differences even in the same habitat.

A survey of river habitats on the River Lune

A survey of the River Lune using River Habitat Survey (RHS) was carried out at 103 sections in February/March 99, to which were added 37 sites surveyed between 1994 -1996. Summary statistics were produced on the distribution and extent of flow features (e.g. riffles, pools, rapids etc.), substrate types, tree and associated features and bank profiles. Information on land-use and management was also included in the analyses. A Habitat Modification Score (HMS) describing the level of habitat modification was derived for each site and compared to the whole reference network and to rivers of similar types in Britain. The HMS shows that more than 70% of the sites on the catchment are predominantly unmodified and very few sites are significantly modified. Highly modified sites are concentrated in the urban areas and on the tributaries.
