ID ?

They look like Crane Fly larvae, especially the ass end where it appears to flare out.



You can also google tipulidae larvae and get quite a few different species.
 
Thanks! I’m assuming they are terrestrial and were washed into the lake by a rain event?

The lake is known for its moth fishing during the summer.

They are classed as semi-aquatic.

Here is what Pat McCafferty says about them on pages 366-367 of Aquatic Entomology:

NOCTURID MOTHS
(Family Nocturidae)

LARVAL DIAGNOSIS: (Figs. 18.7, 18.8) These generally measure 30-70
mm when mature. Thoratic legs are well developed. Prolegs are present on
abdominal segments 5, 6, and 10.
ADULT DIAGNOSIS: (Fig. 18.9) These are generally large, somewhat
drab moths. Mouth siphon is well developed.
DISCUSSION: A few species of this otherwise large and important ter-
restrial family are miners and petiole or stem borers, especially if water
lilies. These particular species are sometimes known as "diver moths."
The Yellow Water Lily Borer (Bellura gortynoides) mines leaves as a
young caterpillar, then becomes a petiole borer. Within the petiole, larvae
are submerged in water and must periodically back out in order to expose
specialized posterior spiracles (Fig. 18.8) to the air before submerging for
another few minutes, Larvae swim to shore to overwinter in dry protected
areas.
Host plants of the semi-aquatic noctuids include water lilies, water
lotus, water hyacinth, arrowhead, pickerelweed, burreed, rushes, cattail,
and bulrush.
