Development of the fishery resources could be advanced by the introduction of 
the following species: the crappie (Pomoxis o-maculat th 
motaguense), and the largemouth bass (Meropterss calaatdes},  CuaPoe (Chchlasom

This lake, about four hectares in area, was examined April 21, 1946. It is about 
ten kilometers north of the town of Chiquimlilla. The water has i 
. a high sulphur content 
and contains no fish. Because of the high sulphur content, stocking would not be justified.

Small Lake Near Huehuetenango 
On May 12, 1946, while driving from Huehuetenango to Aguacatan, we passed a pond 
about one hectare in area, located five kilometers north of Huehuetenango. Only the small 
gulumina (Profundulus ) was taken by seining. The site presents an excellent opportunity 
for the construction of an artificial lake of 25 to 40 hectares or more for the recreational 
use of the people of the city of Huehuetenango. Study of the site by an engineer would be 
necessary to determine the costs of development and the amount of water area that could be 
impounded. It is believed that fishing in the existing pond could best be developed by 
stocking with the largemouth bass (Micropterus salmoides) and the guapote (Cichlasoma 
motaguense ) . 
Lago Izabal, El Golfete, and Rfo Dulce 
Lago Izabal is located about 35 kilometers southmest of Livingston. It can be 
reached by boat from Panzés by way of the Rio Polochic, or from Livingston by way of the 
Rfo Dulce and El Golfete. The lake is about 47 kilometers in length, and 20 in greatest 
width. Its area is approximately 67,500 hectares, and elevation about 10 meters above sea 
level. The lake is oblong in outline with a relatively flat bottom that descends at the 
deepest point to 16 meters (Map No. 2). All of the upper end of the lake has a bottom of 
alluvial detritus deposited from the Rio Polochic. Marginal vegetation covers about tro- 
thirds of the upper shore line. It averages about five meters in width and consists of 
Chara, Potamogeton, Scirpus, Typha, Utricularia, and two or more species of Graminea. The 
south shore has wave-swept, hard, gravelly beaches for the most part, with little aquatic 
vegetation. The north shore is irregular. There are numerous coves, the bottoms of which 
consist largely of md. About four-fifths of the north shore line possesses a margin of, 
aquatic vegetation averaging four meters in width, and consisting principally of tules 
(Typha and Scirpus). 
The lake usually is subjected to strong wind action every afternoon. The wind 
may start blowing suddenly anytime between 1:00 p.m. and 3:00 p.m., and continue until 
6:00 p.m. Sometimes the waves become too high for the safety of boats of 7 to 10 tons 
capacity. 
Water samples taken from the lower end of the lake between 1:30 p.m. and 2:30 p.m., 
April 5, 1946, contained 7.1 parts per million of oxygen at 1 meter, 7.3 at 5 meters, 5.0 
at 10 meters, and 5.2 at 12 meters (bottom). On April 7, 1946, water samples taken in the 
middle of the lake between 9:00 a.m. and 10:00 a.m., contained 5.4 parts per million of 
oxygen at 1 meter, 7.3 at 5 meters, 5.8 at 10 meters, and 5.2 at 12 and 15 meters. At 7:00 
pem., April 26, 1947, water samples taken in the lower end of the lake contained 6.9 parts 
per million of oxygen at 1 meter, 4.6 at 5 meters, and 6.6 at 10 meters (bottom); samples 
taken at the same time contained 2.0 parts per million of carbon dioxide at 1 meter, 8.0 
at 5 meters, and 11.2 at 10 meters. 
Alkalinity tests made at the upper and lower ends of the lake at the time the 
other samples were taken showed no phenolphthalein alkalinity, or only a trace; and the 
methyl orange ranged from 76 to 100 parts per million, with the smaller amount at the upper 
end of the lake.
