The lake is connected to the river via a short channel. Lake micro basin is in the alluvial floodplain of the Napo River, in protected private lands.Although of being a lake associated with a whitewater river, its waters are dominated by the influx of several small blackwater creeks draining the forest.Grande Lake (Cuyabeno River)GL–0.00423 –76.18261 221Grande Lake belongs to the Cuyabeno wetlands system, and it is connected to other lakes through channels. It is a blackwater lake. There are several lodges for tourism along the margin of the lake and the presence of motorboats is common. This lake usually dries up during the dry season.Canangüeno Lake3 (Cuyabeno River)CL–0.04294 –76.19932 220Canangüeno Lake belongs to the Cuyabeno wetlands system. This blackwater lake is connected to Grande Lake through channels. The access to this lake is granted only for authorized research activities and for indigenous people inhabiting the area. This lake often dries up during the dry season.Delfincocha Lake (Lagartococha River)DL–0.59448 –75.24351 196Delfincocha Lake is a blackwater lake in the Lagartococha wetlands, on the right bank of the Lagartococha River.

It is the largest lake in the Ecuadorian Amazonia in terms of area. Although of being a lake associated with a whitewater river, its waters are dominated by the influx of several small blackwater creeks draining the forest.Cuyabeno RiverCR–0.00618 –76.17212 211Cuyabeno River is a left margin tributary of the Aguarico River. It is a narrow and meandering blackwater river that forms a complex wetland system in its middle stretches. Its headwaters are in the Andean mountains and before entering its protected area, it drains lands subjected to land use changes in the last decades.Lagartococha RiverLR–0.59750 –75.23869 196Lagartococha River is a left margin tributary of the Aguarico River. It is a blackwater river, draining a conserved and remote area of the Ecuadorian Amazonia. It is in a natural protected area and constitutes the borderline between Ecuador and Peru.Pacuya River3PR-0.53694 -75.57043 197Pacuya River is a right margin, blackwater tributary of the Aguarico River. Its basin is very well conserved, usually used by Cofan indigenous people as one of their main places to gather food, especially fish.表1. 2021年8月高水位期与2022年4月涨水期的鼓藻类（desmids）采样样点。 1. 湖泊所连通的支流或干流（母河）以括号标注； 2. 纬度（Lat.）与经度（Long.）以十进制度数表示； 3. 仅在涨水水文期开展采样的样点。 缩写说明：CL为卡南盖诺湖（Canangüeno Lake）；CR为库亚贝诺河（Cuyabeno River）；DL为德尔芬科查湖（Delfincocha Lake）；GL为格兰德湖（Grande Lake）；LR为拉加托科查河（Lagartococha River）；PL为皮尔奇科查湖（Pilchicocha Lake）；PR为帕库亚河（Pacuya River）；ZL为桑库多科查湖（Zancudococha Lake）。 样点名称 样点编码 纬度 经度 海拔（m） 样点描述 皮尔奇科查湖（纳波河） PL –0.47311 –76.45954 230 皮尔奇科查湖位于纳波河左岸普罗维登西亚港下游区域，通过一条短渠与纳波河相连。该湖的微型流域位于纳波河冲积洪泛平原内，地处受保护的私有土地中。尽管该湖与一条白水河相连，但其水体主要受汇入的数条源自森林的小型黑水溪流影响。 格兰德湖（库亚贝诺河） GL –0.00423 –76.18261 221 格兰德湖隶属于库亚贝诺湿地系统，通过渠系与其他湖泊相连，为黑水湖。湖岸沿线设有多处旅游民宿，摩托艇活动较为常见。该湖通常在旱季会干涸。 卡南盖诺湖³（库亚贝诺河） CL –0.04294 –76.19932 220 卡南盖诺湖隶属于库亚贝诺湿地系统，为黑水湖，通过渠系与格兰德湖相连。仅授权科研活动人员与当地原住民可进入该湖区域。该湖常在旱季干涸。 德尔芬科查湖（拉加托科查河） DL –0.59448 –75.24351 196 德尔芬科查湖位于拉加托科查河右岸的拉加托科查湿地中，为黑水湖，属于永久性连通湖泊。 桑库多科查湖³（阿瓜里科河） ZL –0.58954 –75.48291 185 桑库多科查湖位于阿瓜里科河右岸，通过狭窄渠系与河流相连。按面积计算，该湖是厄瓜多尔亚马孙地区最大的湖泊。尽管该湖与一条白水河相连，但其水体主要受汇入的数条源自森林的小型黑水溪流影响。 库亚贝诺河 CR –0.00618 –76.17212 211 库亚贝诺河是阿瓜里科河的左岸支流，为一条狭窄蜿蜒的黑水河流，其中游河段形成了复杂的湿地系统。该河源头位于安第斯山脉，在进入其保护区之前，流经了近数十年来土地利用方式发生改变的区域。 拉加托科查河 LR –0.59750 –75.23869 196 拉加托科查河是阿瓜里科河的左岸支流，为黑水河流，流经厄瓜多尔亚马孙地区一处受保护且偏远的区域。该河地处自然保护区内，同时也是厄瓜多尔与秘鲁的界河。 帕库亚河³ PR –0.53694 –75.57043 197 帕库亚河是阿瓜里科河的右岸黑水支流，其流域保护状况极佳，通常被科凡原住民作为主要的食物采集场所之一，尤以捕鱼活动为主。
